In Reply to: How does the preamp affect sound quality? posted by gipher on December 6, 2001 at 12:31:09:
A very interesting subject, so you see I've kept the title in the re line. A good match for your amp would be the Adcom GFP-565 preamp, which has a very good, very quiet, phono preamp. I just bought one used for a second system. Not bad at all. Where do you live? If in SoCal, you could borrow mine to try it out.Now, w/re my friend Doug's comments, I wonder why, in the year 2001, some ee is unable to design an op amp that would sound like a tube? Ought to be doable.
In theory, the best preamp should do nothing. That is, if you use the variable out on a cd player, you should not be able to tell if the preamp is in the circuit or out.
Problem with that theory is illustrated by a strange review of the budget priced Anthem Pre2L preamp in The Audiophile Voice magazine some months ago. The reviewer said cds played through this preamp sounded different from cds played through his "reference" Carver preamp, but more like he remembered a real life performance to sound like. He couldnt decide which was correct. (No brainer here for me.) To go further, I have a Pre2L, and a cd played through the variable out on a Denon 1650ar cdp (this is in my second system) and through the Pre2L sounds different from a cd played on the Denon directly into the amp. So the preamp is adding something to the sound coming from the cdp. Problem is, it sounds more like real life than the cdp alone. Same effect with the Audible Illusions M3a (maybe more so, but I really couldnt tell much of a difference in the midrange between the AI and the Anthem).
So, a very interesting question, how does the preamp affect sound quality? Depends on the preamp, I suppose.
