Hello!
Can anyone tell me, regardless of price, whether it would be better to buy a Yamaha AS301 or the FosiAudio P4 (preamp) + Topping 300mini (amp) "combo" for sound quality alone?
I definitely need the output to connect the active subwoofer! That's why I was thinking of pairing the P4 with the Topping.
Many reviews from those of you who have purchased this or that model, beyond the measurements that I have always given great importance to, reveal that class D amplifiers are more suitable for desktop systems and cannot replace class A/B amplifiers for driving floorstanding speakers with subwoofers! (My satellites have a sensitivity of 84db!)
That's why I need some guidance!
 
Wim Amp Pro - flexibility you need and sound quality too. (Unless you need more than one RCA in)
 
Nowadays, Amplifier class and sound quality are unrelated.

But if you need to drive inefficient speakers to high SPL, then doing so using Class A/B Amps will be several times more expensive, both in acquisition and running costs.

To get the most out of a 2.1 system, an Amp with DSP for sub integration and room correction is essential.

To that end, a WiiM Amp/Amp Pro/Amp Ultra is highly recommended.
