Hi Myles
I have them on separate 20A lines right now but I have a very slight hum. Are your amps with the GAT quiet?
Hum or power transformer hum?
Thanks Myles.
Do I have to reverse the speaker leads with the GAT and ART combo? I assumed with this combo I would not have to.
Myles
Thank you for reminding me about the phase. I thought it sounded a little funny but now it's what it should have been. While I swapped the speaker cables I took the opportunity to put everything on one circuit. The hum is gone. I must have a ground issue. It was not very loud but now it's gone. Thanks.
I absolutely love the GAT and ART combo. it's incredible.
Nope the GAT is a single gain stage so it inverts phase. Thus need to reverse the right and left channel (+) and (-) leads.
Myles, my Concert Fidelity pre is also a single gain stage. Do I also need to reverse the leads? Thanks
I'd check but most likely.
Anyone had a chance to compare ARTs with Ref 250 ?
IMHO you can't compare them. You should either compare the GAT+ARTs versus the REF40 or REF10 + REF250.
Of course the other issue is that the ART is solely single-ended while I believe the ARC is only balanced?
Although the ARC 250 has only XLR input connectors I think it can be used with SE -> XLR adapters. Some older models could not be used that way because they lacked the input inverter, but AFAIK the new models have a FET balanced input stage that can accept SE signals. ARC however advises user to use them in balanced mode.
