The 3020 mentioned above does have a good reputation. However, I think that you can get the same circuit--possibly for less--in the 1020. I've heard some people who have had a 1020 claim that when they upgraded, they had to spend over a $1000 to get something that's much better.
Cheap Old Preamps
I'm helping a friend look for a cheap (under 100$) old (tubed would be great but not necessary) preamp, and was wondering if you all had some ideas for what to look for (probably on eBay). I've been tracking some Dynacos, but the tube ones tend to exceed our budget. Are the SS daynaco preamps just sucky? His sources include an AR/XA TT and a really old Cambridge CDP. Amplification is a 40 wpc (I think) SS McIntosh amp (model unknown). Thanks.
