I played my Yamaha s2300 through a Proceed AVP2+6.
It sounded pretty good.
Recently, I bought a Sony SCD XA777ES used, here on
Audiogon for $1,600. I bought it for my younger brother
for his birthday. Actually, I bought him that and a
Denon DVD 1600, which plays DVD's and DVD-A's. Since
I bought them both used [$300 for the Denon], I had to
open them up and throw 'em in my rack to make sure they
worked properly.
While the Yamaha s2300 sounded pretty good, the Sony
is MAJOR upgrade. Whole different ballpark. On CD and
SACD. I had a hard time putting it back in the box, but
I had to because it was a birthday present.
For less than $2,000 -- and in two boxes -- my brother
can play just about any 5" disc in one box or the other. He has CD and SACD playback that is reference quality.
The Sony was rated A+ by Stereophile and received a golden
ear award from TAS. The Denon has scored highly in both Secrets of Home Theatre and TAS shoot-outs. It is free of the "Chroma bug" and is a nice DVD player. It's DVD-A playback is about the same as the Yamaha s2300.
If you're willing to buy used, willing to go to two boxes
instead of one, and willing to spend another $1,000, you
can get WAY better sound than either a Yamaha s2300 or
a Denon 2900, you get similar DVD quality, and between
them, you can play any format.
If you have any problem finding a Denon 1600, The Panasonic XP-50 will also work in that set-up. It is also a highly
rated DVD player with DVD-A playback.
The other nice thing about this set-up is that when you
get the next urge to upgrade, you can have the Sony modified to take it to even higher levels. Most of the
mod guys have mods for the Sony and the mods have been
well-reviewed. So, in a sense, this set-up is also future-
proof.
