Power cord to add ease and tame treble.

Like a few have mentioned... A power cord is not going to solve your problems.

Here's part of what I think your problem is...Your preamp is not a good match for your amp. I believe Stereophile reviewed your preamp and the most useful part of those reviews are the measurements. Take a look and I think you'll find that your Pass amp does not have the optimal input impedance to mate with the Hovland.

Also, you may find that your JMlabs are not the right choice for your taste and room. The BE tweeter is an impressive piece of technology, but sometimes great individual parts don't make a great whole - just like combining a bunch of "recommended" components doesn't always make a great system.

Thanks for your posts, guys. I mean it.

Mike in NC. No room treatment. Room has heavy curtains both side wall with couch & heavy rug on wood floor. I am happy with the midrange & base balance now. Room treatment has more effect on low midrange + base?

JMCgrogan. The ridge st. cable was no brighter than Au24, Kimber 3033, which are slightly warm. I really like this cable as it adds a lot of focus and front to back layering to the speakers. The diva be has silver-copper wiring so may have some synergy with silver speaker cables. ( Copper would do too if that is the logic.)

Bigkidz. Nice to hear from you. Its is a dedicated circuit that are shared with a few lights in living room which I turn off. Friend can bring a PS audio P300. Would give it a try.

Jond. Had cx-7 into pass x1 both xlr & rca. No sig. diff for me.

Tried the toe in & out. No fix there.

Guess i should try power conditioner or wolff pc or harmonix pc.

Bigkidz, may be i need an Audiologic MXL DAC.

Thanks guys

There will be no fix until you address power filtration...

Glai,

I beleive my original question was, have you tried the Cardas Golden Reference speaker cable?

Cheers,
John

As Big_Kidz and The Psychic allured, you may very well be hearing what noisy untreated AC does to the sonics when the lines are not properly conditioned. But of course, everybody using electricity has dirty/noisy AC.

If you do not have dedicated circuits/lines, then you are also probably getting a double-dose of dirty AC since your digital source would be injecting much digital noise back into the AC (supposedly digital noise is bi-directional) and may very well be carrying over to the amp and/or preamp.

Even if you already have dedicated circuits/lines but no proper line conditioning, you still have AC noise coming into the house and the digital noise will still make it's way back to the service panel and then into your other components from there.

Lastly, I'm not familiar with the sonics of the interconnects or speaker cables you mention. But there are some to many otherwise decent ics and speaker cables that actually induce much grain and hash. So common is it, that this grain and hash is often times mistaken for digital hash from inferior cd recordings.

Other ics and speaker cables will minimize or eliminate this grain or hash leaving you with a much lowered noise-floor and a very pristine, articulate, and significantly improved musical presentation.
