I spoke with Jeff Rowland in person over the phone. He confirmed that the amplifier cannot have a problem and would either work or won’t. The DC problem described above occurs only with class A/B, not D. He also suggested to work on the acoustics of the room. According to him, there is no reason to service the amplifier.
He also confirmed that under powered amp will “blow” drivers, not over power, which also confirms some of the above sayings. The JR Continuum 250 delivers 500w per channel at 4ohms and should be enough for the w/p’s. Listening over 85% is a source of damage to the speakers.
This brings me to the conclusion that I need to get that mic and find a way to work on my room acoustics.
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

@lendivf refreshing to have a manufacturer that is pragmatic and no deal in vibes and feelings. YES, it is a learning experience but getting to know what your room/speaker synergy is like in Room EQ Wizard takes out the mystique of many issues people attribute wrongly to other things. Good luck but also man, you listen too loud. your hearing must be shot (a visit to check your auditory health is also something to look at) |
@kofibaffour thank’s for the advise. As a dentist working with a succion unit blowing in my ears 12 hours a day for the past 25 years, no doubt, I’ll end up with a hearing device one of these days. I must admit that I’ve always liked the loud listening, but moderately compared to some guys. |
My Boulder 866 comes out of mute when it’s out of standby at 33 out of 100 on volume scale. You can barely hear anything. Listening at volume 60 is absolutely normal. Pass labs gear is very similar in thar you end up listening at volume 50 and up. I used Audio research Ref6 preamp with Pass X260.8 and going beyond 15 on volume was loud and that’s due to ARC having higher gain. So as I said earlier each amp and preamp is different. You can’t say going above 40 signifies a problem. Also, when I had the PS Audio DSD MkI DAC going into preamp using balanced cables I found that it was noisy if set to 100 or preamp bypass on DAC. At 97 on DSD DAC it sounded the best. |
