Good to hear that. Is this the unit you got, and is the frequency control effective/fairly accurate?

At the end, I found this DIY kit:
Velleman Kits K1803: UNIVERSAL MONO PRE-AMPLIFIER – Velleman – Wholesaler and developer of electronics
...and it performing good. Its gain is set by trimmer.
Currently I have it set at approx 30%.
Now its enough to set TPA3116 amp's volume knob to about 30-40%, to achieve the same volume level like it has before, when it was at 100% volume.

That Lusya preamp not arrived yet. When it arrive, I will have some preamp for the future projects at least :-)
I have order another TPA3116 amp with it, this one is PBTL mono only. Not like the previous one, which you can configure by soldering pads to 2x50W stereo / 1x100W PBTL mono.

And it have better sensitivity of 500mV. I am curious how it would perform without Lusya preamp, or with it.
