Help needed for my setup...

[Bapt44]

Good day everyone!

I do apologize if it has been already discussed but I really cannot find the answer to my question....

My setup was as per the following:

Turntable FLUANCE RT81+
Peamp FOSI audio box X2 tubes
Amplifier FOSI TB10D
Speakers KLIPSCH R51M

About a week ago and out of nowhere I started to get a huge humming/buzzing sound that was getting louder when turning the sound up. I changed the RCA cables but no changes at all so I took the decision to just change preamp and amplifier.

I just bought and received amy preamp FOSI X5 but I am struggling in choosing the amplifier. I was thinking AIYIMA A07 Premium or AIYIMA A70 (given Amir's review). I am just using everything to listen to records in an office and I do not need a lot of power, just something to give me a good sound quality for under $300. What would the best amplifier be for my need and my budget according to my gears?

I'd appreciate any help in choosing, thanks a lot!

I took the decision to just change preamp and amplifier.

Have you checked which devices are causing that huge humming/buzzing sound?
Try connecting another sound source to the amplifier itself and see if there are any anomalies.

At this moment, if I turn on the FOSI TB10D with the preamp FOSI X5, that humming/buzzing song is here and awfully loud. If I bypass the preamp by using the integrated one from the turntable with the FOSI TB10D, it is much better. Still that buzzing sound but not until I reached a certain point when turning the volume up.
