+1 on the Ultraverve from Dehavilland. I bought one used for less than half your budget and immediately sold my Primaluna preamp. The Ultraverve sounded much better than the PL in my system. I rolled many tubes in the PL but to me the key is the UV is a 6SN7 based unit. It made a big difference from the 12AU7 PL. Bigger, more natural sound, yet all the detail is there and more space between instruments. PL makes good products, gets all the reviews, and served me well...but Kara Chaffee’s product is much better in my system. She is great to work with on new and used gear. If you have a problem, questions, etc. with your gear, there is nothing like speaking directly with the person who designed, built, wrote the manual for, and shipped it! Just my opinion.
