I have had this amplifier for over 2 months now, could not be happier. Absolutely great product! You mention there's a slight buzz coming from the tweeters when putting your ear next to it, I think this has more to do with the tubes rather than the amplifier itself. I have not tried it without inputs - here is the thought - but it is the same kind of low level buzz as I get from my Musical Fidelity m8s-500s, which I consider normal. Another amp, FirstWatt F5t is dead silent. I tried Tungsol 6L6 STR tubes for the output stage with Psvane 12AU7S for pre/driver and this combo is absolutely silent. Lovel sound as well. After few weeks came back to the original JJ tubes, as I find those somewhat more soulful, more fun so to say. Also tried it with other speakers; JBL L90's, Focal Aria 948, Paradigms, Visaton La Bella, etc., could not tell which ones I liked the most, they all play quite nicely. Anyways, great review and comparison. Thank you for doing it.
Love Brunoco. The amp sounds real great with Devore O/96. Also with Mon Acoustic PlatiMon speakers. I wonder how their 300B amp sounds like versus 6L6PP.
@@supergiddy3 300b has wider, taller sound stage. Brighter upper midrange and more air on the top end. Has a bloom to the sound. Terra sounds darker and has better control over the bass and goes down much deeper. I would say 300b’s bass is no slouch either, still very good.
