Folks, I feel morally obligated to tell you that this model, and probably the series, is really good sounding in every way.
I use it with Infinity Kappa 5's and 24 bit pc DAC. (DAC upgrade on list)
My upgrade path has been: Musical Fidelity A220 class A (for many years)
Then to a Marantz PM - 7200 . The Marantz was overall better and super fast, but has some character to it's sound. A good character though..
The A220 would improve with a better op amp..
The Sony TA-700ES is gonna be HARD to beat folks, it hits about 4 or 5 audio nails square on the head!
Clean, Detailed, Flat response, uncolored, powerful, extended soft highs
As I continue to listen, it keeps amazing me with the low level details - extra background voices, the buzz in blues guitar - my gosh, this is a good one! Sooo accurate.
Leaves me wondering if the mosfet models sound better!
They are very serviceable too! I found the transistors to all be within 2 mv at idle!
I removed the phono board because it crowds up the pre driver stages, and put binder clips on a few stand alone transistors that run kinda hot.
removing the phono board seemed to improve the sound slightly.
The only weakness may be that there is no thermal protection, and the power supply is large for output stage. Further, there is no fuse between the output stage and supply caps - this is hit and miss from what I've seen on amps. I would rather have fuses after the caps.. perhaps it helps the sound quality in some small way like it is..
That's being picky, I know, but the output stage should not be the weak link in my experience. I can't believe the 800ES has the same output stage, but has added another transformer!
I like the Thresholds having the transformer as the weak link. Safe, and I have yet to see a broke one for sale.. (don't think I will unless it's excessive user error!) LOL
I keep a close eye on it and it's well vented, being my desktop system!
I'm an audio nut, and have heard many amps. This is one good integrated. All the knobs are solid aluminum!
Gotta give respect where it's due!!
Now I can't help but wonder how the mosfet models sound!!
This is an 87 model folks, and beat out a 96 model (A220) and a 2004 model ( PM-7200 ) in sound quality and power.
The PM-7200 was closer in sound quality, but the A220 was closer in power.
Maybe the A220 would do much better with a better op amp?
One more thing about the sound, it has a deep depth to it, while the others had about 2-3 feet of depth, this one sounds 10 feet deep, if that makes any sense.
