I would bet 100 euros the gain will be below 10 dB lol.
Annnnnd... you just lost 100 euros.

There is a high and low gain switch on the rear panel. I saw a comment in an ASR post saying he was willing to bet 100 euros the gain of the LA90 must be below 10dB "I would bet 100 euros the gain will be below 10 dB lol." So let's examine the high gain Dashboard:

The same can reach 120, and in the power curve that follows, we can also see that there is almost no difference in the performance of high and low gain!

So 2x90W in 4 ohms for this ultra-silent amp. Desktop users rejoice, living room users look elsewhere.

And from a local supplier - no worries about warranty support. Admittedly not integrated, but I have MiniDSP flex already on order which will be my preamp.

This one is not for me I think.

Do you know of something similar to the miniDSP flex but with BALANCED inputs and outputs? Does this come with a TRS balanced option?

Topping offers with its LA90 a powerful and efficient amplifier, which can work both in stereo and mono mode. In the first case, it is capable of delivering a power of 2x90W under 4Ω (1% THD+N), in the second it will be able to provide a power of 180W under 8Ω (1% THD+N). Moreover, the LA90 provides a combined balanced input connector, the device being able to be connected as well in Jack 6.35mm as in XLR.

Topping dominating the low power value.

Next time when he wants to publicly humiliate me perhaps he should do it while measuring power at 5W or 1W instead of arbitrary power outputs at 25W and 50W.

He is obviously maximizing the noise part of SINAD this way.

Eitherway i’m very impressed.
If you feel offended, then I apologize to you. A big reason for using 25W to measure at high gain to achieve 120 SINAD is that the signal generator of the APX555 can only generate a signal with a SINAD higher than 120 at the corresponding amplitude (slightly more than 1VRMS).
