I have a pair of Preludes and they are wonderful, very musical speakers. I am currently using them with a TAD-60 amp and TAD-150 Signature preamp, but I have tried the Preludes with other equipment and found them equally impressive. They are very efficient, 91.5db/8ohms, I believe, and therefore tube-friendly. Lovely midrange, surprisingly low and tight bass for such a small speaker. Highly recommended, and Mikhael Shabani,the owner of Renaissance/Morel USA, is a great guy.
