In Reply to: RE: Follow-Up on Earlier Post and Some Notes on Sony HAP S1 (long) posted by oldmkvi on February 12, 2017 at 10:22:12
I believe what was happening is his CDP only had variable output and it was turned all the way down. The HAP was fixed output.
That's why the mismatch.
OP can confirm?

Yes I read your post.
I wonder what the input sensitivity on the Int Amp is.
My Mac 6900 is 2.5V. His must be 0.5V to be too loud w/Sony.
There's no reason to even use the CDP, except as a transport/Coax/Opt anyway, with the S1.
I would suggest he remove the attenuator and just live with it as his only source.I'm glad your suggestion got him going-

You're right. From what I can find about input sensitivity for Classe products circa '90's 00's it is low.Which would still be okay but in his CAP 101 the db increases are incremental and at low volume are quite large over a very short range before they taper off to .5 dB steps.
So with the HAP at 2.5mv fixed output he is hitting full volume very quickly.
Fancy volume circuitry and read out display. (Can't just put a resistor across the pot!)
But looking at reviews as recent as 2014, that old discontinued integrated can still hold it's own.
Essentially he is using his passive variable out set low on his CDP and now has a variable passive on his HAP. Maybe not the best sonically, but more flexible. (Sorry I keep repeating myself!)
I'm in the same boat with an '80's pre, but have learned to live with essentially 4 positions on my volume control for line source. 16 steps or so with phono.
Cheers!
