... when you crank up the volume with Ety4S, something you can't do very much with something like OPA637 or AD744 class A. After a certain loudness level (pretty loud actually), a lot of recordings, even of decent average quality, become too grating.
I heard that exactly and wondered what was going on. I had not read
anybody mention this before. Still the SM-3, OPA637 (etc.), and
Ety's still sound good together (I agree to their above shortcoming), and
there are still other opamps that outperfom. What Great Options!
My SM-3 came with the NE5534 opamp originally. I liked the NE5534 alot, but
it was too warmish for my likes. But the BASS, I have never heard my ETY's
with that much bass ever!
My Question: How does the NE5534 Class A biased sound in comparison? You
said that "Once again, class A biasing seems to burn away a good amount of
veil and haze. Transparency improves as well as detail. Treble becomes less
soft and bass more tight and slamming."
* Does the TREBLE Highs Brighten significantly?
You should try the AD8610. I liked the AD8610 alot for vocal music, Beautiful
Vocal Resolution! But IMO the bass was not resolved as well, boomy bass shy
with the Etys.
Jon L, where did you get your AD744 at? Analog.com or Digikey? (Sample
Availability?) I have to try the NE5534 Class A biased, and AD744 Class A
biased in my SM-3 now.
