Which amp with Wilson watt puppy 8

@lendivf 

Yes, the Jeff Rowland continuum 250 seems to be a high end amp.  It is also rated favorably at 4 ohm.  On paper, it should work well with the W/P 8.   However, it is quite dated, so, you need to make sure it is running properly.  Any hum ?  Check the DC at the amp terminals and make sure that it is less than .05 volts or 50 mv.  Note:  I was running my old Adcom 585 LE in my home theatre and it started sounding distorted.  I checked the output terminals and the left channel was outputting 5 volts of DC at idle !!

Yes, I can vouch for the sound of a the pair of Mc275s with the W/P 8.  This will definitely sound good.  I like the earlier suggestion of McIntosh amps.  Both Tube and Solidstate McIntosh should sound good with those speakers...  Also, depending on how much those W/P 8 have been played on high volume, to make sure it is inspec, you might want to change the 3 resistors underneath the "Watt".  You can buy the resistors from Wilson.  It is an easy change.  I recently changed all my resistors and I believe it was a good move.

OP- since you already have the Wilson speakers, just ditch your current amp and get a Pass X250.8 and Pass Xp-22 or a Cary SLP if you want some tube sound, then, a pair of good speaker cables and start there. play around the positioning of the speakers in reference to your listening position. 

we have tested many class d amplifiers including Ice, hypex, ncore and a few others none of these amplifiers were as musically engaging as our better class a/AB amplifiers

so the first thing we would recommend is trying a new integrated amplifier 

particularly a hybrid design 

our owner Dave Lalin personally owned wp 3 and fives and setup dozens of pairs of wp over 20 years at sound by Singer,

so give us a call we can assist you.

Reading the above comments and other discussions, I’d say you need to whip out the checkbook. As said here, your Class D is dated. It’s time to face the music and write if off. If you’re not in position to bring out the checkbook in a big way sending it in for possible refresh/repair is your last option. My bias opinion is to go the Pass Labs route for it appears to be a good match with Wilsons based on multiple readings on this forum.  It’s a safe bet but not adventurous. Tubers have a good argument to go the tube route or a combination of solid state pre amps, amps and tube. This is the fun part deciding which direction to go. You need to get a handle why you are blowing speakers. Abnormal. Usually its the ear drums that blow first.
