ARC LS26 power cords, interconnects, tweaks

I just purchased an Audio Research LS26 preamplifier. This is my first tube component and now my system could go fully balanced if I invested in xlr cables. I am very happy with the overall sound of the LS26. The separation of details and fuller sound in the midrange is an incredible improvement in many ways. Tones sound so natural and true through this preamp. That said, I do not feel I am getting the full level of performance it is capable of. My former pre was a solid state edge g1. There was a sparkle in the treble that is not there with the ARC and while the midrange is certainly fuller it sounds very slightly veiled especially on voices. I am sure this is just a tweaking issue as it really does sound incredible. I would love to hear from other owners who have experimented and what you've learned.

I currently own all Tara Labs RSC interconnects terminated with RCA. My system is:

amp: spectron musician 3se mk2 (isoclean superfocus power cord)
preamp: arc ls26 (shunyata taipan power cord)
cdp: resolution audio opus 21 (shunyata taipan power cord)
loudspeaker: audio physic scorpio: spectron remote sense speaker cable / purist audio new elementa advanced

Thanks

Hi there,
Audphile is right, get at least 400+ hours on your LS26 before making any judgements. Mine has, and I'm still amazed at how un-hifi it sounds, and how it just lets music 'appear' in my room.

No way that the LS26 can be making vocals sound veiled. It must be a system interaction. Try borrowing some different inteconnects and see if that changes anything.

I find the LS26 sounds a little more dynamic if you use the high gain setting. Balanced cables will be a definite plus if the associated up/downstream components are balanced.

I have my preamp on a spliked mdf platform. I use Daikom footers (like Aurios)under the pre for isolation.

I have never felt the need to try different PC's yet, it sounds so good 'as is'.

I'm using a Cardas Golden Reference PC (with Oyaide plugs and receptacles) that used to power my Krell preamp before I bought the ARC.

I'm using the incredibly transparent and musical Gabriel Gold Revelation I/C's. They are the perfect match with the LS26.

Relax and enjoy!
Cheers
Mick
