Amp suggestions please...need some power


Looking for a SS amp that can comfortably deliver 250-400+ish wpc into a 4 ohm load and can be had <$1500 (used OK). I own PSB Stratus Goldi and by comfortable I mean the sensation of doing 60 mph in a Ferrari - you ALWAYS know its there if you need it.

My system is evolving from an integrated to separates and will probably mate with a tubed pre. My media is 50/40/10 vinyl/digital/FM and I prefer a sound that is more warm than analytical but do enjoy drive and detail.

On my list -

Bryston 4Bst
Parasound Halo a21

If you have a recommendation of a synergistic, tubed preamp, I'm all ears. No phono needed, remote is nice but not mandatory - budget <$1500 (used OK).

Any and all input is appreciated.

Thanks!

If you want to be able to mate with a wide variety of tube pre-amps, choose an amp with a high input impedance, say 50k Ohm or greater.
Sunfire SRA or Sunfire 300. Side by side compared with Wyred but liked more sunfire(only if connected balanced though)
I had Goldi's and used a Rotel RB-1090 which will deliver over 700W to your PSB's and they will love every watt. It was a great combo. After my first RB-1090 I walked the upgrade path to Nuforce and even the hallowed Parasound JC-1's. Neither was that great with the Goldi's. I ended up buying another used RB-1090 after I sold my first one (duh) and was much happier than when I had the "better" amps. I spent good money and effort to find that the grass was not greener on the other side. The only reason I don't still have the speakers and amp is I moved to a much smaller home and that combo was ridiculous in my new small hifi room.
I do like that Rotel RB-1090. And if you're sitting down - also consider something like Emotiva. The XPA-2 is 300W/ch into 8ohms & 500W @4ohms for $709 shipped, and if you're willing to stretch the budget just a little then a pair of new XPA-1 monoblocks gives you 500W/ch @ 8ohms or 1000(!)W/channel @ 4ohms for $1658 shipped. I know they're not nearly as esoteric as the other suggestions, but these are all amps and they should all be just pure clean power w/o coloration, right?
