Interconnect suggestions for Audio Research Ref 5SE?


Recently acquired an Audio Research Ref 5SE to replace my LS-16.

Had been totally pleased with the open organic sound of WyWire Diamond interconnects with the LS-16 but find the Diamonds to be rather bright with the Ref 5SE, emphasizing the mic and the very top of female vocals.

Have reached out to thecableco.com for a few samples from their library....Shunyata Alpha, Cardas Clear,...amongst others.  I also have a pair of Nordost Valhalla 1's coming from another vendor for consideration.

Really excited about the 'grunt' and more forward sound the Ref 5SE brings to the game as it helps with presentation on the Grand Funk, Allman Bros, John Mayall, etc. I listen to...along with the acoustic, jazz, and classical....that make up my primarily vinyl collection (Audio Research Ref Phono 3, VPI Classic 4, Proteus Transfiguration)

But, so far, am missing the open organic clarity I guess the LS-16 and Wywire brought to the table. 

The Cardas and Shunyata seem a little recessed, the Nordost Frey seemed a bit recessed and analytical. They all resolve the brightness but seem to be holding back everywhere else.

I've been going back and carefully leaving the various cables in place for at least a few days...

looking for suggestions... Kind regards, and thank you in advance!

Given what you said I suspect the Valhallas you have coming in may be an improvement.  Are you using XLR interconnects, and what length?

No experience with Audio Research, but I would definitely add Audioquest Thunderbird XLR to your audition list.  You're on the right track.  Bringing in multiple wires for audition is the way to go.  I went through the same process about 4 years ago.  Happy listening.  

Thank you for the responses! 
 

Have been listening to Synergistic Research Atmosphere Excite for a few days now.

Dropping the Cardas Clear back in today and will listen to those again now for a few days.

my understanding is Audio Research prefers balanced interconnects. So that’s what I’ve been doing (except for phono cable of course)

I’ll mention this Acoustic Zen Silver Ref. II as a potential option as I own it and it excels in exactly the areas you’re looking to improve yet still offers good tonality and natural sound especially for a silver interconnect.  At this very attractive price if it doesn’t work out you can easily sell it for little/no loss so very little risk to try and could potentially save you $$$ if it works out.  Best of luck in your search.
