I seen a few people place them among the higher tiered amps, but isn't each Glenn OTL customized specifically for each owner? Won't that make each of those amps vary drastically from each other?Or is the customization just cosmetics?punit, placed his on par with Woo WA22, Bottlehead Mainline &Cavalli Liquid Glass in his list awhile ago.
The Teton sounds a lot different from the Glenn OTL, the Glenn has more dynamics, more bass, and a warmer sound than the Teton, it is not as fast or as transparent as the Teton, the Teton has more refined treble as well. The Glenn amp is more forgiving and I believe its a slightly more powerful amp as well.
Valhalla 2 - had to say it, it's the only amp I have. But the HD800's sound damn good with it to me.
Try mods on the HD800 if its too thin and diffused sounding. Some people are using HD600s and HD650s instead of HD800.
Sorry, but I owned the Oppo HA-1, and I could not stand my HD800 with it for even 30 seconds on pretty much any track except for the mainstream pop songs. It is one screachy sounding DAC/Amp, but I'm pretty sure the DAC was at fault.
