Audio Research Ref: CD8

What I've Learned: I spoke with Leonard at AR and asked him if this upgrade is a sonic improvement. He advised that it addresses a specific issue: if the existing two tubes in the power supply drift apart in their values this can cause noise. By going to a single tube instead of two tubes, this is eliminated. Because AR is covering this at no charge, I would imagine that they see this as correcting a problem.

Great to hear that the CD-7 upgrades gives a nice sonic improvement. I'll be sending mine in soon.

Man, that's good news. I'm excited about the better bass that the CD-7 update apparently provides!

Ossocao-

Thanks for your perspective. I was plaining to send in my CD-7 for the PS update today, but now I'm not so sure whether to do this or not... Most people on this Board have said that the PS update improves sound, especially bass, but you clearly say otherwise. Should I go forward with the PS update?? I don't want to do this if it will make my sound worse!!
