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!

You can't go wrong with monoblocks. Here is a pair of B&K 200.1 monoblocks for $1500.00/pair. One of the better bang for the buck monoblocks available. No affiliation with ad. Very potent amp with warm/neutral characteristics.

Power Rating: 8Ω----250 watts

As Sufentil (my old friend) wrote look for the Sanders amps. Innersound was his, some of the Coda amps were clearly his and now he has his own line. These are potent amps for made for much tougher loads, -you'll be cruising.
I have heard nothing but good thing about the Wyred 4 Sound amps I think by Cullen Circuits. If you can find one at your price the H2O ICE amps were a power sensation a couple of years ago. Same for Spectron but they are prolly too much$$ even used.
You can buy a new Wyred 4 Sound ST-500 for $1499. These amps sound great and put out 250wpc at 8ohms and 550wpc at 4ohms. I have the integrated STI-500 and love it.
Threshold S/500 currently advertised on this site for $1400 with 250 @ 8ohms and 500 watts @ 4 ohms. Maybe I should buy it. That's a lot of amplifier for the money.
