I love Japan especially Mt.FUJI, SUKIYAKI, and PARTS. This channel is for DIY PC, Loudspeaker, and Tube-amp using high-end parts from all over the world. Enjoy!
As you know, if the feedback margin is small, the sound will deteriorate. It is possible to increase the margin by increasing the mass. However, this causes problems with resonance at a certain natural frequency. Just like the dispersion of standing waves, this problem can also be avoided by dispersing the natural frequency. By the way, the SL1200 has this idea in the player itself.
@@seaslyd Many years ago I was experimenting making legs from concentric pipes. Brass on the outside, copper on the inside, filling the space between the tubes with molten lead and the inside of the copper tube with some very soft silicone. Each foot stepped on a square piece of thick cork sheet. I was not satisfied until I discovered legs made of "sorbothane" (a hemisphere that continued into a cylinder) in a light gray color. I replaced the previous legs - expensive to manufacture - with the latest ones that were pressed on the square pieces of 1 cm thick cork. Since then even with the amp at full power at a party nothing mics up, nor does the arm/head/needle bounce (even with the cover open)
@@gamiwv I think that in many cases the limiting factor for the sound quality of an analog record player is the "howling margin". Improving the installation environment tends to make it more inconvenient to use. The SL1200 for DJs is an analog player developed for use in harsh environments, so it's perfect for me.
I like both very much just from a sound perspective! Each has it's own benefits. From a musicality standpoint I prefer the TRP-006 though. The musical performance touches my heart somewhat more with this. Did you already try the OPA892 or OPA891?
1:52 ~ 3::09 vs 6:01 ~ 7:17 the 2nd sounds to me more "attractive" but then again it is just my personal taste. Maybe this comparison but driving SEAS BIFROST (if you still have them) ?
By the way, my impression of this conversation is that you are a friend from 100 years ago. My videos are not for sale, they are just a hobby. I have plenty of space in my office (I am old but healthy and still working) and BIFROST is on standby.
@@seaslyd Nice sound lovers. We are friends in this way even if I turn 69y.o.(only) at the end if this month. In Greece was not permitted to work (officially) after 67y.o. so I'm in "retirement", but I remain an engineer.
After listening to the video 5 times, I definitely prefer the one with the OPA2828 (2nd version). It is more balanced as I hear it from my system. In the first version, I hear the consonants "ch", "t", "S" overemphasized (they are scratching my ears. As if the diaphragm that smooths them out has not been placed in front of the microphone). It is possible that the first version has a somewhat wider stage presence with the singer vaguely placed somewhere on the left.
Nice sound ! Paper woofer (with fabric surround ?) . If so, could stand for 40+ more years sounding equally nice. What is the IC of the power amplifier and the double triodes of the pre-amplifier ? Let me listen the video for one more time (at least !)
@@seaslyd Valuable chain of reproduction ! Μore than 45 years ago I was using E88CC (a radar IF tube not so difficult to find ) on a (mono) PHILIPS amplifier (6L6 output SE). I remember how hot the amplifier was and in our summer parties I had two small bedside table fans to cool them (as it could be done with the temperatures we have in Greece)
@@seaslyd Somehow you tempt me to take down boxes of "old stuff" (tubes) from my attic and try to build with E88CC (cascade mode) a per-amplifier at 90V ~100V Va
i had seen this speaker at 15~16years ago. From korea audiophile club. tad unit tech. oak 50years barrel of suntory wisky(no wood sticker wrapping) It make me save a holding worth. Of course jbl is better. But i surprise. Even small size , it have a nice mood about Something missful feeling like nostalgia. very good sound color,matching with tube amp . 3d stage some less. But forward position from woofer and soft silky tweeter. accurate rythm. Expressed harmonics of instrument. Not wet misty but good sun at morning. correct vocal and stringed instruments. it is a such like well maked fullrange speaker. eazy damping. good control phase difference. I kept hear these and i was enjoy. very good muisc list. Thanks.
You must be a very skilled sound engineer. Accurate and precise understanding of the situation. Gentlemanly behavior. A highly educated and trained intellectual. I use the influence that sound and music have on human vital signs. My goal is to stimulate the subconscious of my clients to relax them and increase the safety of my work.
Very nice components selection especially capacitors. My only "remark" is that I will place a metal sheet shield between the PS and the amplifier (somewhere side by side to the 2 red capacitors 5:40 ) but again it is a matter of experimentation. I hope it is a diy amplifier (so all the credits to you)
I selected the parts and built it myself. I paid particular attention to heat and long-term reliability. The mil-spec foil resistors and silver-cased wet tantalum capacitors are of the highest quality, and are of the grade that can be used in aerospace and nuclear plants. The solder is Nassau and Kester 44 silver additive. This is a boutique amplifier with point-to-point wiring.
006mf : NEVER muddy. Never hazy. Super clear background. position of instruments is very accurate. . it make sound more "Lively stage and Fun" Flat tunning. Fun+Monitor sound. muses05 : normal hifi, high and low band both good. best vocal of these. but little lightly dizzy. almost good. but little unrest cause of too much greed&energy. 1622 : eazy . thick. powerful. but i dont like this. no stage. no clear. not separated mass. no emotion.
I'm glad you listened so carefully. Like you, I can hear distortion and noise in the left channel in the "Hotel Suite" section. Few people can clearly hear the difference between monolithic ICs and discretes these days. Your analysis is the same as my impression on the ground. I'm not sure if I was able to present it clearly in this video. You are a well-trained expert and I respect you very much. Thank you for your comment. I wish you happiness.
@@seaslyd I'm sorry in midnight and thank you for your friendly answer. I'm as excited like a child for your reply. I did not meet the same person anywhere. As a technician, you have a great skill, but maintains a transparent and consistent attitude on a humble and accurate standard. It's great as a technician, but I feel like music and I feel like the right person. I hope you flow as you want. Thanks to you, thank you.
I cannot completely separate analytical facts from tastes and preferences regarding my impressions of sound. I am very interested in what qualities of sound stimulate the emotional center in the hypothalamus. Your impressions and analysis are very helpful.
Здравствуйте, ваше понимание очень правильное. Мне тоже нравится 3. У него хороший и точный звук. Но если я сравню ее с другой песней, то могу получить другой результат. Я тоже согласен
I can't really spot difference. My objection is for the "electric piano" and the non very distinctive positioning of the singer (somewhere to the left in the most of the recording) . Generally very pleasing sound
