Amps Choice for 87DB sensitivity Bookshelf

Thanks a lot for the recommendation, appreciate!

I've try both of Pass & ARC, they are powerful amps with high-caliber.

However, from aesthetics side, their blood is not suitable for Pawel in some way...

From my initial understanding, Pawel may need aliving flexibility, speed & transparent with high requirement on capacity of voltage swing & moderate current output. I don't know if I am right on the character, but still waiting more recommendation...

Try a Pass XA-30.5. It's an over achiever and bettered our X-250.5 everywhere except percussive base. We used ours until we purchased our pair of XA-200.5's.

An XA-30.5 can be purchased used inexpensively and resold for little if any loss. You can always set up the Pass XA amplifier model line and get improvements with each higher model.

For a pre-amplifier, I used an Audio Research Ref 5 SE. Pricey yes but worth it. Only sold it because we went all digital and no longer needed a pre-amp.
