@@matldn2697 I had SCM 40's before. They have really gone up in price £3200?. I paid £1500 in 2012

@@cp070476 True, but I am looking at Wilmslow audio, as there are some amazing speakers there. Also I am thinking of using a Chord 1200C power amp.

Darko Audio said that being an audiophile is a journey, with the "fun" of always having to upgrade. I did the opposite, after a decades-long hiatus from hifi. I spent a few weeks doing my research, then landed on the Adam Audio S3V monitors (got a killer deal on them at a local Guitar Center) back in April 2022. Ever since then, I've been watching all the "journey" videos, subscribing to many audio channels, just to affirm if I made the right decision and wasn't too rash (after all, there are hundreds of speaker manufactures out there). I can now say that I saved a lot of money and headaches, and perhaps had a little luck on landing on these awesome speakers from the start. Also, there is no "junk" between the speakers - just our fireplace, which keeps the wife happy. I have a DAC underneath one of the speakers mounted in the stand, and a cable running from the sofa to the DAC, which I hook my smartphone up to. It's a great feeling to have a 21st century upgrade in audio!

Anton Chigurgh thanks Anton. That’s great to know about the timespan. I’d love to go longer sometimes, but editing well and in an engaging way kind of limits things. I totally agree about your comments re bad in bad out with these speakers. Thanks again for feedback!

I have ATC CA2 mkii preamp and ATC P2 amplifier, I'm thinking about the ATC40 passives, but I'm also wondering if trading the P2 in toward the actives is worth it. I assume some increase in quality, but also could I just get passive and be as happy.

Thank you Caroline. I didn’t have Hegel then tbh, obviously these are actives . I’m offering advice on patreon or PayPal as I need to make this work. Links in latest vids. Best wishes Simon

Good one, enjoy!

@@13thnotehifireviews7 The only glitch which I experienced was a year ago when one of the Bass units started to fail, an ominous slight rattle when playing a certain Organ CD, fourth movement of Widor’s Organ Symphony No.5 showed this up. The dealer Orange and Lemons from Clapham picked up the speaker and replaced the faulty unit and since then, no problem.

I liked the atc sound but I think you need a really good room set up with the flat response. My room is a little small and so I prefer a smaller floorstander and one with a little bit more treble then ATCs. That’s not to say it isn’t a fantastic speaker with the amount of realistic timbral information going on.

@@13thnotehifireviews7 The only problem, if you can call it that, is the brutal honesty of the speaker, you play a sub standard recording and it will sound just that and more. Play for example a half speed mastered vinyl disc such as Peter Gabriel’s So or any of the recent Tony Visconti David Bowie reworkings and the SCM40s just sing! Play the 2018 so called CD remasters of Curved Air’s first three albums and the over the top compression and digital clipping sounds dreadful.

​@13thnotehifireviews7 can I ask what are the dimensions of your listening room , did you have any boom or room modes

Tom Peluso thanks Tom, really appreciate feedback. Cheers Simon

Thanks very much!!! No pre amp with the RME - straight into the ATC’s. Obviously they will benefit from much better DACs, just didn’t have anything better at the time. Ideally you’d want to use a really great pre amp straight and/or a DAC onto the ATC’s. Maybe something like a Chord DAVE which is a very good pre too. Or better still dCS Bartok. Or maybe something cheaper like a Hugo TT2 would be great too. A Bryston BP17 cubed (BP17 3) pre amp I tried was terrific and that would be what I’d try with something like the dCS if money was no object. Not to say these ATCs don’t sound terrific with a modest DAC like the RME though. I suppose it’s a question more so of getting the most out of them. They do need good space and set up too.

@@13thnotehifireviews7 thank you for replying (so fast)! I am wondering if their cda2mkII would be a good choice (I have auditioned the combo and its great but still..) vs the ca2mkII with rme (or Qutest ? ) I am afraid that the budget is up to those dacs! Thanks again!

GoldenEars Thanks for your nice comments again. Naim are a difficult firm to deal with and unfortunately they ignore all but the very established magazines where they know the review will always be positive. That said I did think the Nova worked ok with pmc twenty523 when I briefly heard it together in a Sevenoaks. Not enough to say buy it because I didn’t a to b. But naim to me are one of those brands where you don’t get that much for your money. £4300 for streaming, an 80w amp doesn’t seem like vfm to me. Especially as those pmc’s love power. Instead for a bit more I’d look at the Hegel h390 or lower price/power like h190. You can run Roon off of the hegels I think and since so much of the sound is due to the quality of amp and power, it makes sense to go with most gutsy you can get. I suspect you could get a Hegel h390 at the same price as that naim and it will sound infinitely better. Maybe then add a cheap Roon server too if you’ve not done roon - I can heavily recommend. This Hegel h390 is definitely one I want to review so watch this space. Message me on my website if you want more info.

GoldenEars what did you think of my recommendation out of interest. Any concerns and thoughts?

@@13thnotehifireviews7 how would the bartok sound directly into these, another component you highly praised, and would that be a true 1 box solution or would a good pre amp such as atc s pre amp boost sq, and still be becessary cos the bartok pre amp is only so so?

Thank you And for lower volumes...I add a pair of RELs T9...and a pair of RELs Tzeros But only for listening on lower levels of volume That is ... All the best from 🌞 Croatia👋

On off button on each

keeperofthereign no worries, glad you liked it. They were very good.

Hi" This is Charles Presently IAM Using old Generation Passive SCM40" So if i upgrade to New Active Scm40 will Shows Tremendous Difference or Just Marginal Difference

Jeevan Motors can’t answer as I haven’t tried, but I think you will prob hear a big diff

As far as preamps go, and basing your budget off the price of the ATC speakers, your best "all around" bet would be for the PS Audio Stellar preamp. Its solid state and has an incredible DAC built in. If you insist on tubes, go for the Rouge Audio RP-1. Both of these units retail at around $1600, and feature an IR remote control, something not commonly found in hi-end preamps. Both companies are revered amongst the audiophile community and the chances of dissatisfaction are exremely slim!

I think you have to weigh these speakers up on lots of things other than treble response. Things like integration of drivers and authority etc. They are excellent speakers although personally I prefer speakers which have more treble - the PMC twenty5 23i speakers with a Hegel H390 would be superb for me.

It’s what subwoofers are for.

@@rogermatthews2760 I'm confused (and always have been) . Why do subwoofers not have to match the "main" speakers? To me this seems perverse and illogical. Matching the same manufacturer's subwoofer to their speakers seems a no-brainer?

That’s what I thought. Trying a rel sub atm. Another way is matching the sub with the main amp with high level connection - running off speaker terminals and not rca output of amp.

@@TheManunderwater When possible, there is a case to be made for using the same brand main and subs, if only because the manufacturer has developed them to work together. Yet, the vast majority of sub owners aren't using the same brands as the main -- and not talking about problems doing that (presumably they would). Are they all "perverse and illogical" fools? That's the question it would have been better to research and think about before posting. I won't claim to know all the reasons why, but one obvious hypothesis is that at least in most cases our hearing is not sensitive enough to pick up any low end discontinuities. This would be all the more the case when the main speakers are allowed to run full range and the subs come in only within a very limited range, e.g., ~44 Hz with my 40A's. In that case, the two are cross pollinating so to speak, their differences effectively impossible to tell apart.

Haven't tried tbh, but I think ATC regard the active version as better because of all the benefits you get with an active crossover. I prefer a speaker a bit more incisive as you need really good rooms to make these shine I feel.

Thanks for the very prompt heads up. I was thinking of getting the SIA 150 coupled with the SCM 40's. The alternative would be to purchase the actives and a separate preamp which would be more expensive. I also don't like the idea of amplifiers integrated with the speakers. B&O also use active speakers and they are even more expensive. My concern is that it seems that one needs to play the ATC speakers loud. I live in an apartment and I am not into playing music loud. Just wish for crystal clarity in my jazz, classical and easy listening music.

@@huangjin800 you shouldn’t be concerned about amplifiers in speakers , it is often always the much better design. See my article on active speakers on my website if you read the atc review there are links to it. You don’t have to use massively expensive pre amps with these speakers. They are very responsive to the pre amp but still work really well.

@@13thnotehifireviews7 Thank you for your kind reply. I will read your article. Although it is noted that to do these speakers justice they should be played loud; something I am not keen on doing.

@@huangjin800 I didn’t find playing loud was a pre requisite for good sound at all.

Richard De Gannes really don’t know tbh as I’m not ATC and just reviewed one speaker , best to ask them.

Hello Richard. If you have a chance go straight for 100ASL or even 150ASL. I auditioned 50ASL and considered to purchase a pair. A friend of mine got 50ASLT but very soon upgraded to 100ASLT. In terms of dynamics, both are excellent, but you may miss a bit of bottom end with the 50 and may decide to add a sub later. Don't let the size of 100's to fool you, they don't need a huge listening space (most of the studios using either 100 or 150 are rather small in size), moreover, 100's may perform better than 50's when you need to play them at a lower volume. In any case, you can't go wrong with ATC. Regarding the pre-amplifier, I auditioned with the Audio Research LS27 tube preamp, I was very satisfied with the result. I hope that helps.

@@all2088 Thanks for reaching out. My listening space is 19 ft long x 13 ft wide. I would like to get the 100 ASLT (Active) with the ATC SCA2 Pre-amp. Do you think that Active speakers can be used for Home Hifi. I read where they said that ATC speakers are very neutral speakers, what are your thoughts on this set up and how do you think it will sound. Thanks.

@@all2088 Do you have an email adress to reach out? Thanks.

@@richarddegannes2928 Hi Richard, sorry for my late response. Personally, I would suggest going for an active version of ATC. Apart from saving on power amps and interconnects, the major benefit is their ability to play any genre of music equally well. There are few very good demos on RU-vid, for example, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5mw9wjuE_6k.html. They have few videos with both active and passive versions to compare. Obviously, ATC pre would be the logical choice, unfortunately, I didn't audition ATC with their own preamp, but you have a variety of preamps with XLR inputs to try or even a DAC with line outputs like FCS for example Bartok. You can also check the following system as a sort of reference: instagram.com/edmund_vinyl?igshid=11uez1mecpyau

It might overkill in your room .. is better to get the 19A or 20 A pro .. even SCM 7 with a good amp will really impressed you .. by the way 19A and 20A uses SL driver , while the 20A using reference tweeter same as the 50s , 100s .. 20A is a better bargain

I thought they are ok, but like most speakers they perform better when you turn it up

I think they, atc, rate the active version more. The only thing is when trying other speakers and particularly room correction kit, these don’t quite have the flexibility and adjustability of some gear with such a flat frequency response. You really need such a good room to use them.

No not atm. Pmc, kef and monitor audio I have currently.

Nothing special re xlr. Which pre amp is how long is a piece of string tbh. You might want to try ATC amplifiers as a starting point.

Maybe the Atoll ST300 Signature Streamer-DAC-preamp? Gets excellent reviews and is relatively affordable. Dual Burr Brown DAC offers an organic quality while being detailed.

Have to watch whole thing.plenty pics online too. Cheers

better get down the gym and get rid of the double chin then. lol

Probably not, but "on paper" actives are always better as the amps are perfectly matched to the drivers. If i was starting over, I'd go active in a minute. As I have $ invested in a good amps, and such, I will stick with that. For the quality, sound, and the fact you don't have to buy amps, those 40A are a steal in the audio world. They cost about the same as my 803D's.

@@willbrink I use a DEQX and 6 channel amp and tri-amp the passives whilst dialing in the room acoustics. This setup can outerform much more expensive passive systems

Thank you

I think in the U.K. about £7k and approx 10k USD. Contact ATC for prices.

@@13thnotehifireviews7 thankyou! what pre amp match atc40a is well?

The new pmc twenty5 23i are much better vfm speakers imo. So bigger models in that range too. Check my vid out and subscribe....

@@13thnotehifireviews7 Cheers Ill check em out subbed earlier thanks.

Subscribe to Patreon too if you like, as all reviews now going on there.

John sweda I suppose that might depend on whether the cabinet interact too. Tbh that’s all academic and the point is space. Sorry these are not mine, they were from ATC and have gone back but I could put you in touch with a dealer if you email me on my website.

I prefer speakers with more bite. Forever how impressive Atc is they can be bland with treble

Self evident….They have no purpose for the acoustic design or for us.

I’m a traditionalist in hifi and not too fond of subs. But you definitely do not need a sub with these ATC’s!

I think you need a decent sized room

Thanks for the advice. I’ll check out the 19A’s. Really heard good things about the SCM19v2 passives and expect even more from their active cousins

@@13thnotehifireviews7 can you define what you mean by adecent sized room? What would you consider to be the ideal room size for these ATC scm40s?

Yes because it looks like the Matrix Audio has an analogue pre amp with xlr outputs to the ATC’s xlr inputs. Personally I’d spend a bit more on upstream components to get best from these speakers, ideally. The RME I used worked well but they are responsive to the DAC and pre amp. My pick of the gear I’ve tested would be a Bryston pre amp.

13th Note HiFi Reviews Thanks for the reply I currently have the scm 40 s . Are these in a different league to the 40s ? If my budget was £12000, that’s £7000 gone on speakers leaving £5000 for pre amp, streaming dac and streaming bridge. Was thinking of the G2 AURALiC, matrix audio, as my front components but that’s a,ready £7000. Any suggestions?

Go on my patreon for further advice I’d say. We’ll thrash it all out
