Anyone using NITES on their CD player??

What kind of CDP are you using? Instead of buying a PC just for the sake of it's reviews, get the CDP in your system & get used to the sound first & then decide what direction you want to go with PC changes.

I would also recommend AC upgrades before PC upgrades, which include but are not limited to dedicated lines & upgraded outlets. Filtering is another aspect too.

Spend your money much more wisely!

I recently tested a bunch of PCs, including the Nite. I liked the Nite a great deal, but it really sang on my amp (Spectron Musician II--the Nite was bested only (and only very slightly) by an Elrod 3s). For my Granite 657 tube CDP, I preferred, by a wide margin, the Omega Mikro Active (red in my case) from Walker Audio. The OMA PC is delicate, but I haven't found that to be a problem for me. They have a 30-day test period. I second Driver's observation that PCs are system dependent and you need to try them out.

No, I haven't tried the Nite on my cdp, but have heard good things about them. I also have the Granite 657 cdp and have found cords make a significant difference. While the DIY cords I have tried provided some improvement, they are not in the same league as the better cords. I wish they were, it would save me some money.
The best of the lower price cords I have tried on the cdp is the Syn. Res. A/C Master Coupler which is found regularly used for <$150. The latest cord to provide the best improvement in my system on the cdp is the Music Timbre, from W Enterprises NW. It is made from a gold/silver/copper alloy wire.
The Silent Source Signature, also from Walker Audio, is highly recommended by a friend who still uses the Omega Mikro as his favorite.
Another friend swears by the Foundation Research LC-1.
There are so many choices it can get confusing, but one good thing is most companies have trial periods so it's virtually risk free.

I have several Nite power cords. Ended up using them just about everywhere, except my Marantz SA-1 front end. There the BMI Shark sounded best.
Cheers!
