What are your go to LP's for evaluating new gear or new tubes?

I will check on that. I'll try most anything once. Cd's can usually be found for just a few bucks. I will not call you names. :)

I have several Von Karajan recordings. Most are on good labels. Haven't started listening to them yet but I'll get to it. Thanks for the suggestions.

I found Pat Metheny in my Cd collection. Not really sure how it got there but I'll give it a listen. It does get mentioned here and there.

I will have to check out some OS and AP re-issues. A lot of re-master stuff was terrible but this is different. I guess this is why people stream, it's so easy to check something out without buying it. Thanks for the suggestions.

Have some October Project on my watchlist. Thanks

Just picked up Op 3 test records 1 and 2 on ebay. Vinyl. Looking forward to having them.
