Another bump to the thread. I have been auditioning some 7308 / E188CC tubes with the Garage1217 adapter. Thanks to Brent Jesse I have been experiencing an expanded soundstage, richer sound with less grain. My previous tubes are the WE 396a and my former favorite, the TungSol black plate D-getter. The WE was a little to soft for me, but I have a nice 6SN7 tube pre, which the combo might be too much of a good thing. But the 7308's are just a great addition to my modded Orchid. Thanks 213cobra for getting the idea started here.
MHDT Orchid TUBE ROLLING
Interested in hearing about tube rolling experiences with the Orchid and other MHDT dacs, namely, the specific comparative sonic characteristics of the various 396a, 5670 and other compatible tubes used in the output buffer. My only experience is with the WE396a that Linear Tube Audio installed in my new Orchid.
