High output voltage DACs, preamp input concern
OK, thanks for the link and comments. Good explanation.  
What was the first power cable that you noticed a difference in the sound?
Unfortunately never actually, maybe I thought so initially, but I was skeptical of the placebo effect. I’ve owned Nordost, Pangea, Shunyata, Wireworld. I am currently running aftermarket Cullen cables. They are very well-made, reasonably priced, b... 
ARC Ref 6 Tube Microphonics
@tokushi thanks for all the suggestions I will definitely try those. I’ve kind of just gotten used to it at this point. I also have a BAT preamp that uses the 6H30 and does the same thing.   
ARC Ref 6 Tube Microphonics
@lcfpimentel No, other than the chime the preamp is very quiet. I do notice though after a few hundred hours on the new tubes and when they’re warm, the chime is reduced. Also it was much more pronounced when I was running it with the Hegel amp wh... 
ARC Ref 6 Tube Microphonics
Yep, I switched from the Hegel to another amp that I have, a Benchmark AHB2, which has an input impedance of 50k ohms and the chime was still audible but very much reduced such that one would not consider it an issue. Speakers are Harbeth 40.3XD ~... 
ARC Ref 6 Tube Microphonics
@hsounds Thanks, I will try that, also I wonder what ARC is charging for a 6 -> 6SE upgrade??  
ARC Ref 6 Tube Microphonics
@tattooedtrackman It sounds like a small high pitched cymbal hit due to the vibrational shock of the relay transmitting via the PCB I suppose. It only happens when coming off of volume 0 when the relay kicks in.  
ARC Ref 6 Tube Microphonics
The single ended connection between the Ref6 and H20 appear to be much more cooperative at 300 ohms / 50k ohms.   
ARC Ref 6 Tube Microphonics
Interesting, I am using the Ref 6 connected to a Hegel H20 and then to a pair of Harbeth 40.3XD. I believe the H20 has higher than average gain at 32dB. Also the output/input impedance matching of the Ref 6 and H20 appear to be just barely OK with... 
ARC Ref 6 Tube Microphonics
Thanks for the detailed response. When music is playing, I don't notice anything out of the ordinary and I love the sound of the preamp so maybe I will ask ARC about some of their selected tubes and just live with it. Appreciated.

Patrick shipped out the order today after another email, sounds like he has been way too busy, oh well, it's just cables, hopefully he can catch up with the demand.  
Cullen Cable
Well so far we are coming up on one year since I placed my order and no cables yet. I am waiting on 3 XLR interconnects and 2 power cables. I email Patrick every month or so, if I remember, and he always replies and is pleasant and says they will ... 
Joseph Audio Perspective2 vs Harbeth SHL5+
@prof Thank you for such a detailed analysis, I own a pair of Pulsar 2 Graphene and a pair of Harbeth 7ES-3 XD and I could not agree with you more on their characteristics, in fact, you described things that I regularly hear with the Harbeths but ... 
Cullen Cable
I have not and for a $1200 order placed 2 1/2 months ago I’m getting a little concerned I understand and trust his reputation online but.   
DAC diminishing returns
@yyzsantabarbara I thought about adding a second AHB2, would be interested to know opinions on the improvement over a single stereo. Agree on the DAC3B, was too bright and hard sounding, put it in the system a number of times and it never stayed i...
