Hello, I have owned many McCormack products over the years including DNA 0.5 Deluxe amps, TLC and TLC Deluxe with EPS (External power supply) preamps, and an ALD preamp with the SMc Audio B+ upgrade. I have also owned the DAC1 Deluxe and SST-1 CD transport. Ok, I am an admitted fan. I think the equipment is not only an exceptional value, it is also great equipment regardless of price. Steve McCormack really knows his stuff and has been very helpful whenever I have needed to contact either Steve or his coworkers. Professional and courteous. All of the preamps are very good, very even handed and open. My personal favorite of the above mentioned models was the ALD with the SMC Audio upgrade. Virtually holographic, dynamic, with very real sound. I can still remember listening to Lenny Kravitz 5 and having it sound live in the room. The impact and depth of the kick drum comes to mind. I have used these preamps with Vandersteens, NHT 3.3's, Mission Cyrus speakers, and Klipschorns, all with great success. McCormack gear and Vandersteen speakers seem synergistic. Good Luck!
