Hi all, I have my amplifier assembled but am having problems with ground loops/buzz. I've started another thread if anyone would like to help. Thanks

Hi everyone, my Akita has been in use for more than 40 hours, what do you say is enough to judge how it sounds?
Unfortunately, due to the covid-19 block, my family members are all at home, I can rarely listen at high volume 😀😀😀

Hi, I'm sorry I can't help you, try writing to Vitaly privately so he can help you

Think about First Watt 😉

Sorry, I don't like listening at high volume with efficient speakers, they only bring headaches.

Vitaly, if I wanted to use the amplifier as a power amp, I just exclude the potentiometer, right?
Can I use the Topping E30 as a pre?

Salvation! Nerone, The volume at home is managed by the dac ... So potentiometer fully!!!

Dac ak4497.

 

[drMordor]

OK, but digital adjustment degrades sound quality at low volume levels

Thanks, tomorrow I'll try with the pre E30.
I can't wait for your amp to arrive to see how you connect it to the vu meters 🙂

So what's the best solution?
A tube preamp?

 

[drMordor]

Good pot)))
to - 30db in digital, -30 to silence potentiometer

I can't understand, do you mean that a good potentiometer similar to the one already mounted is better or should I install another one?

 

[drMordor]

already mounted very simple pot.
Need use step pot
10-50k, not more

 

[nerone]

Alps RK27?

 

[drMordor]

It's not bad too

Would you have to use linear or logarithmic potentiometers in this case? And if a 10 to 50K ohm?
For example, in my ICEpower 125 I have not installed a potentiometer and the volume is regulated by a tube preamplifier.
I am satisfied and have not made any changes to date ....
