Sub $500 Hypex or PFFB Amp for Kef R3 Meta? (USA)

[iTenth]

Looking to get an amp to power R3 Metas. I plan on sitting 15 feet away from them. I've looked at getting a Wiim Amp Ultra and according to SPL calculators, they should be find but i'd be maxing the amplifier.

Many of the Hypex amps end up being >$575 with Cheapest Nord AMP and Audiophonics being around $550.

I’ve looked at:

Topping PA7

I’m mainly looking for a transparent amp that’s not load dependent. It seems with PFFB being introduced into the budget amplifier market, they are now rivaling many more expensive Hypex Ncore Amps.

Not interested in buying a Fosi or Aiyima.

The plan was to pair it to a minidsp HD then Wiim Ultra or Wiim Pro. If it’s not possible might just get the Wiim Amp Pro or Sonos Amp.

What inputs did you use on which SPL calculator? I find it difficult to believe that the Wiim Amp Pro (there's no Ultra that I'm aware of) would have any difficulty driving the R3 Meta to meet your SPL needs unless there's something unusual in your requirements.

For example, to get an average of a bit over 80dB at your listening position, which is quite loud, you're looking at needing 2 watts:

At the Wiim Amp Pro's full 120W @ 4R, you can get a bit over 100dB for a dynamic range of about 18dB, which should be sufficient for just about anything:
