For Past & Present Sonus Faber Stradivari Owners
I have them in a 13'x19'x10' room, 6' from back wall, 8' from tweeter to tweeter. Initial they created a lot of echo because of their height. Custom made absorption panels from floor to ceiling took care of that problem. They are driven by First s... 
Input voltage and your poweramp
They're GamuT M250 monoblocks. I have 2 pole main coming into the house. Circuits on 1 pole measures 116-118V. The other pole measures 121V. Moving the amps to 121V sockets didn't make any difference. Also tried an UPS with voltage regulation. Gam...

Samtse, I am using First Sound Presence Deluxe 4.0 Mk II. I am hoping to upgrade their higher end 3 box preamp.

Hi Nico_g. Nothing wrong with PASS, but in my system, I just love the Gamut sound. I am using tube preamp with the Gamut. The PASS, even with paired with PASS pre-amp, sounded like ordinary electronics. Yes, the M250 is better than the D200 in all...

I hate to send them back, but I may have to do that. When I was listening to the cello suite late last night, in between the notes I could hear the transformer hum. My listening position was 12+' away. Sound meter on top of the mono-block chassis ...

shortly after my last post, the amps started making that loud noise again, though not as loud as last friday morning. i put a sound level meter on top of the amps. it measured a constant 61db on one, 59db on another. it sounds like the transformer... 
Gamut M250 MK3
yes both amps made that noise, though one was louder. it's been 2 days since that incident. each morning when i turn on the amps, i could hear the same kind of hum, but at a very low level. i had to be right next to the racks to hear it. as the am...

Granted that there might be DC in electrical network, but there it has never cause any amp to hum this much. I've live in this house for 10+ years. The D200 was connected via the same AC cords to the same outlets for 1+ year. I am trying to determ...
