I have a Transcend "Push Pull" EL34 amp, and I believe it's upgrades are close to a Level 2. Since it is 1.5 years old, Aric didn't label them the same. It is the same unit that Terry London reviewed for Stereo Times (which was upgraded before it was sent to Terry); and he added more when it got back to him after the review. You will love the amp, my other tube amps were boxed away once I got the Transcend.
Aric supplied the Transcend with Sylvania "Bad Boy" 6SN7. I also have RCA VT-231s that I bought from Brent Jessee, Ray Tubes 6SN7 "Select", and Linlai E-6SN7s. My audio room will be finished late may or so, and I'll start tube rolling again.
I too have kept my CODA S5.5, and like you I ADORE it......an amazing amp. I run both amps from Aric's Motherlode XL preamp......amazing combinations.
