Topping A90
Nov 14, 2020 at 1:22 AM Post #916 of 1,442
Now, that is a disappointment since the Abyss is not push to its potential in terms of power. Always thought the HPA-4 is also a beast when it comes to power and transparency. Does the A90 on medium and high gain provide sufficient power for the Abyss than HPA-4.
The A90 can handle the Abyss PHI without issue. With the Benchmark I would have the volume at 100% and it was still not enough. And this was after increasing the gain via the DIP switch internally. But the Abyss is a special case. Amps designed for it have 6 to 16 watts of power. I ended up using my Benchmark AHB2 amplifier directly from the SpeakOn taps to the Abyss. That 100 watts at 8ohms became 17 watts or so at 47ohms.

It was at 433$ yesterday at shenzen audio, from 499$, for 11.11 shopping day offer. Probably will get such discount for black friday too.
I really would like to get an amp pre amp like this one, this isze, etc... But that volume knob, it's such a huge facepalm... why would anyone want such a flat volume knob? since when anyone ever liked a flat volume knob?? I would get me a schitt magnius, but that one is much worse then this one on several levels, very bad single ended, no function switch, gotta unplug the hp....

Any decent alternative to A90? Has anyone been able to remove the knob?? thanks!!

THX AAA 789 is pretty similar.

A90 much better input out put options, and maybe a90 is real balanced, 789 is not really balanced, certainly not for preamp outputs for sure already, no xlr output, only rca. I want XLR outputs for my speakers.

No you're right, the A90 has more option in terms of connections. The knob is pretty much the only weak point of this amp. I think it's well worth the money.

Think most folks choose the D90
Bifrost 2 would be a better combo. Using all Topping was a bit fatiguing. Very clinical.
