Which amp with Wilson watt puppy 8


Hi there !

i live on an island with no audiophile shops around. 
I arrived in 2011 with a Jeff Rowland continuum 250 and Sonus Faber Cremona m speakers who were a great match. Unfortunately I blew the speakers a few times, then upgraded to columns, blew them also twice. I guess the amp is too powerful for them, but this time Sonus Faber was unable to provide me replacement tweeters and speakers, which is an enormous disappointment. I will never buy anything from them again. I ran through the web and found corresponding parts that I changed myself, but they seem to sound much higher in the trebles and lack bass, especially at high volume levels, (above 55%) . I tried swapping the cables, but it didn’t change anything. 
I now bought a pair of Wilson audio watt puppy 8 that arrived this week from a NYC store. I hope them to last lifetime. 
They have cost me around 11.5k$ door to door, look great and tough, but need to be driven above 60 % of volume otherwise nothing comes out of them, especially bass !
I also get the same sharp treble sound, which is very disappointing.
My problem is to find the issue : 

1/ room acoustic

2/ change my class D amplifier for tubes or transistors

3/ find better cables

4/ me turning old ?

what should I do next ? what amplifier would you recommend with this configuration (watt puppy 8, MIT Avtr 1, ps audio direct stream mk1, aurender n10, musical fidelity M6 CD) ?

thank you

Thanks to ya’all! Lots of useful information. Thank you @lanx0003 for your master class in physics, sorry I didn’t catch all of it, although I have a PhD 🥸.  
Maybe you could send me more details in private (with a physics/maths lesson😜)
Decibel X is a nice simple tool. I did a little test drive. 
First, it happens so that the sound is nicer using my ps audio DS’ preamp in direct mode. 
Second, I can go up to 100 on that preamp and the speakers will follow no problem. At 100, I get +- 90dB coming out. (I tried a few seconds very gently, I can already see a few 😲 and 🫣’s out there). 
Going back through je JR, that level is reached at 80%, which means there is another 20% extra dangerous power (or whatever you would call it), and the speakers would go above 90dB …(I didn’t try) That is the accidental range on this amp where any driver would be damaged, especially tweeters at high frequencies (I saw them smoking last time, the membrane literally melted while pushing the volume up with a test tone) 

Seems like Pass Labs are very appreciated by WA owners. Looking for PLb’s,  found a pair of Chord spm1400 mk2, and Mcintosh 12000 with good discounts. I wonder if anybody has tried those. 

Something is certainly wrong. I drive my Wilson Alexia's with a pair of Conrad Johnson's big LP275M tube mono blocks (eight ST120 tubes in each one) with fabulous results. I can play Pink Floyd's Dark Side of The Moon, or AC/DC Thunderstruck at levels that are well beyond sanity, or the ability of artwork to remain on the walls of my listening room without any notice of distortion.

I have acquaintances that have terrific performance with WILSONs paired up with a full cradle-to-grave MARK LEVINSON system with those  beefy mono blocks .

@OP I would not pair a Chord amp with W/P 8. Chord's house sound is the antithesis of, for example, Pass. It will magnify all the weak points of the speaker. The Pass XA series amps do work very well with Wilsons including those that use the Focal ti tweeter.

BTW Quick comment on Wilson resistors. They will protect drive units to a point. But if the speakers are massively overdiven on a transient or with a short, at least the tweeters will fry before the resistor has time to blow.

OP looks like you’re deliberately trying to push the electronics and speakers to their limits. You will end up melting the resistors on the Wilsons in the best case scenario. Is there any logic behind this? What are you trying to accomplish?

It appears that the OP might consider another hobby. Needlepoint perhaps? Doesn’t sound like this high end audio thing is really a good gig for him.

100% true.   It happened to my Wilson - Focal 1" inverted titanium coated tweeters. I did something stupid.   Wilson repaired them for $400 each - back in 2019.  Great customer service!  Had them back in 2 1/2 weeks.   Re-installed them DIY.  All is copacetic again.

@steakster - glad you got sorted out and +1 to Wilson.

@OP - were you Nigel Tufnel in a previous life?
