I got these great M2 two weeks ago to be my home reference audio, (future home studio also)
I was totally following the book, I got one
Crown I-Tech 4x3500HD to power them.
The good result
: out of box they sounded just perfect! all the details, the accuracy, nothing is more or less. They are the great speakers to spot any recording imperfection.
The bad
: the
amp fans are unbelievable noisy, they are 52db without any load @ 3ft distance and 60db in front of it.
I placed the amp in a closet, in order to minimize the fan noise, which actually did. Then I was able to do an actual 2 hours of listing.
Here are my results, (mixing board was set to 0 unity gain, I-tech amp is set to -25db) beside the sound is perfect, after about 1 hours of listing I felt that this is more than enough. my ears got tired. They needed to get rest after about 1 hour of listing in this volume.
There is noticeable too high distortion or THD, to be used for long hours of listening.Now I decided to return the amp, and look for an alternative amp so I can enjoy listening to the M2.
I will try to get 2 Crown I-Tech 5000HD to see if things will get any better (Which I doubt).
After several phone calls with JBL pro, they advised that I can use any amps I like with BSS Sound web London, but the amps has to be no less than
1200 watts per driver. To me this is next to impossible to find any Hi-Fi or even Studio Amp even close to that number. The only option is use a touring amp like
Crown's,
Lab Gruppen or similar...
Even
Bryston highest wattage mono-block is only 1000 watts, and it cost about $12000 each mono, which will be $46000 for the 4 mono's!!! I think this is way too much.
Even Mark Levinson will cost somewhere close to that with half of that power.
I am sure there is something I am not able to understand, but I really need to find the amp that can handle these monsters!
I need help please
My previous home system was
JBL Ti5000 with Musical Fidelity A5, they sounded very nice (not as perfect as the M2) but I was able to keep listening for several hours with high volume without getting tired of listening
