Looking for a new tube preamp


Currently using a Cary AES DJH preamp with various 6SN7 tubes & NOS EZ81 rectifier. This is an excellent sounding preamp with point-to-point wiring. Looking to upgrade. Would prefer very realistic uncolored preamp, even better than what I have. What can you suggest? Running a McCormack DNA-1, driving Von Schweikert 4.5 speakers. Silver interconnects and speaker wires, multiple turntables and CD/SACD player. I've read some good things about the Shindo Aurieges. Not sure if its output impedence is a good match for the McCormack. Also thought about Modwright. Upper spending limit is under $4k new.

I'm using a DNA-1 Deluxe in my system. Check out Mapletree Audio Design. I recently had the DR. build me a custom line 2 and it sounds just like what you are looking for.Uses 6SN7 tubes with a 6x5 rectifier. Two chassis design.Custom is less the $1500.00

From SAS website:

•Changes in amplifier input impedance, 20k ohms to 100k ohms, will change the tonal balance, especially in the bass/mid range. The 11A has an adjustment to compensate for changes in amplifier input impedance. No other manufacturer that we know of has this feature.
