Amp for use w/ REL Stentor III?


Hi all,

I recently took delivery of a REL Stentor III sub (damaged in shipping, thanks UPS!). Unfortunately, unlike the pic on REL and Sumiko's website, there are NOT dual left/right input jacks for either XLR or Neutrik inputs! I am told that this pic is of a prototype and this feature never made it to production. Major bummer...

The problem is that my amp (Ayre V-5) is balanced differential output so it is impossible to hook up the REL as a mono summing sub. I have called Sumiko and Ayre and neither had any bright ideas except to buy another Stentor(!). So my question is: Are there any amps out there that are as pure as the Ayre (corny, I know, but it IS a really good amp) but with common grounds at the speaker binding posts? I prefer SS and balanced inputs if at all possible. Equipment is Wadia 830, MD Etude, ARC LS12, homebrew monitors of flat 4ohm load.

Thanks for your suggestions and happy holidays!

Thanks for the suggestions. I tried using the Ayre's RCA and XLR grounds as suggested by several people including Sumiko, but to no avail (hum from the REL). I've escaped without damage so far, but don't want to keep messing around until I blow something up. From talking with Sumiko, it sounds as though there were circuitry problems getting the separate stereo inputs to sum properly, which is why they're not on the production units. And the REL only has a mono RCA input, so no dice there either. Maybe this will be solved on the MkIV...
Y's can be used for splitting, but summing is more difficult and I personally wouldn't try it, certainly not without some inline resistors at the very least.
