Interconnects for Pass Labs X260.8

@jjss49 thanks but hard to imagine these cables approach the resolution if the AZ Absolute Copper. I swapped the DAC to pre with AZ Silver Ref II and it toned down the heavy bottom end so may be you’re onto something with your silver recommendation.

in my experience well made well balanced cables of silver or silver plated copper invariably provide a little more air and sheen up top compared to straight 100% copper cables... this assumes the maker is not doing some tricks with insulation/dielectric or shape of the cable (like nordost ribbons) to suppress the bottom end and fool the ears into thinking the copper cables are super resolving up top

of course, as always, ymmv

I was going to suggest the AZ Silver Refs, but you’re obviously already familiar with them so is there something holding you back from trying them between your pre and amp?  

@soix yes…I don’t have the XLR shorting pins..my silvers are RCAs. So I’m only able to try them between dac and pre

@moto_man mine are actually the original Sabrinas. But I don’t think that matters much. I might give the alpha v2 power cords another shot. These X260.8 amps are drastically different from the 30.8. They have full control of the speakers. And the bass now is much better than it was with the 30.8. I’m starting with the XLRs first. 
And yes, I’m tweaking the room acoustics to tune the room to these amps. It’s a process…

Why not just try these Silver Refs, and if they don’t work out just turn around and sell them for little/no loss.  That’s what I’d do anyway   Best of luck.
