Amplification for Wilson Watt Puppy 7s or 8s


Putting together a new system and would like feedback from those within the community who own Puppy 7s or 8s in particular. I am trying to narrow my choice regarding amplification from the following. Would appreciate your feedback regarding your experience using these in your system:

VTL S-400 Reference; VTL 450 monos w/ VTL T.L6.5 preamp
BAT VK 150SE monos w/ VK 52SE preamp
VAC Phi-200 monos w/renaissance preamp
E.A.R. 890 monos w/E.A.R. 912 preamp

My listening room is 25"L x 17'W x 12'T . I listen to all genres of jazz, blues, house music, classical, gospel and spoken word. Yes it is eclectic but I truly love all forms of music. From time to time I will turn the volume up quite high but this is the exception, not the rule.

I hope to acquire most, if not all, of the components pre-owned but well taken care of. If I need to buy new, I will as a last resort.

OK Guys, I've had 3 hours with the McCormack DNA-750 Mono-Blocks (750 watts/ch into 8 ohms, 1000 watts/ch into 4 ohms) in my system, which consists of:

Conrad Johnson CT-5 Pre-amp
McCormack DNA-750 Mono-Blocks (Demo for a week)
McIntosh MVP-871 (Upgrade Company Modified) CD/SACD Player
Whest PS .30 RDT Phono Stage
VPI HW-19 MKIV TT w/TNT Platter/Bearing
JMW 10" w/Ortofon Jubilee
Crystal Cable and Transparent Audio Cables

Not sure how many hours are on these or if they are fully broken in yet, but they have a very smooth controled sound. Maybe not the last word in detail, but smooth, effortless, and tight/punchy bass. No solid state edge or grain. Very organic sounding, at least compared to my Spectron Premier. They develop very little heat, but are larger than the Spectron Musician III MK2.

My goal is to compare them to the Spectron Mono-Blocks and be done. Comments/questions are highly recommended regarding these high powered work horses.

Thanks,

Samhar,

I don't know if these have the current to control my Watt Puppy 8's woofers. They need to go into a fairly well ventilated cabinet(WAF), so I prefer amps that don't generate a lot of heat. I believe the DNA-750s operate in class AB and the Spectrons are digital, so neither generate much. The McCormacks were played pretty hard for about 3 hours last night and were barely warm to the touch. McCormack/CJ claim they only need 15 minutes to warm up. I cannot confirm that yet. But they created a very involved musical environment within the first hour. A second glass of wine may have also helped.

Again, I am initially pretty impressed. Plus, I found them for quite a bit less than the Spectrons.

Thanks for your responses,
Lubes3
i know you are close to nailing this down but thought i would throw out another to consider. as much as you seem to like the speed, detail and efficiency of the spectron you may want to look at spectral. dma 250 would be a great match or even an older 180. for the maximum, depending on budget, dma 360 mono's which wilson uses in design and has for many years. you will not match the speed and accuracy of these amps, no way no how.
Lubes3 sounds like you've found what will work for you great!!!

FWIW I've heard the WP-7 with the Jadis 200 in a word fantastic. The WP-8 impedance drop to 2 ohm might be too much for the OTL's good point.
