Carver Raven 350 Amps

Good to hear you got it sorted out.  Bob was saying he provides the XLR input for people who only have XLR outs.  Similarly, the 4 and 8 ohm outs are also tied together but when he provided a single for those two he got a lot of questions.  The 2 ohm is separate as it internal requirements differ. 

Like I said, oddly enough connecting via XML makes mine quieter.  Probably, the RCA out on the DAC is generating the little bit of noise.

So yours are dead quiet now?  Even if you put your ear up to the tweeter with nothing playing?

I really like those, very nice.  I went with quilted sapele on mine, can't wait to get them.  Also, I have an SS7 center coming in the same finish.  At 23% complete right now so likely still be a few months out.

I went searching for you on audiocircle last night and found your post (assuming it is you) in the thread with the guy who is using the 305s with his SS10s and came from an AVA 600R.  Looks like multiple people are enjoying the pairing of these amplifiers with SoundScapes.  This is good to know.

erichgs,

Yes dead quite. If there is any noise I can't hear it. 
BTW, I also placed rca non shorting caps on the rca inputs. Perhaps that's what took it to zero noise.
Everything matters...

Now to experiment with input tubes...

The Benchmark DAC3 has jumpers to attenuate the XLR output.  I moved the jumpers from the default position (0db) to the middle setting (-10db) and now I am noise free as well.

OZZY, where did you buy those rca caps

erichgs,

I have moved my jumper and output settings on my DEQX premate to its highest output settings and still no hum. 
I can't tell you how satisfying it is to have discovered the source of the hiss. It was amazing that I missed something so obvious for a week.

smokenjo,

They can be purchased from  many places. I bought mine off of EBay from a guy located in Michigan, they are of  very high quality and with fast delivery. Now remember these are caps not shorting plugs. I have used them on all of my unused rca and xlr input/output throughout my system.
