Thanks Rodge827 for the suggestion. I should start building my own amps. Unfortunately I have too many hobbies as it is, maybe in a couple of years if and when I can afford to retire.
Goldeneraguy, I borrowed the 845-G SE's some time ago and I thought they were wonderful with my Merlins, although I bought a Joule instead. It would be interesting to hear what the 845s do for the Hornings. I have Thoress preamp thats the best audio component I've purchased in a long time. It's what led me to picking up the Thoress amp as well.
Charles1dad, true the 300b is hard to beat but I've never owned a 2a3 or 45. Can the Hornings handle 4 watts? I've heard that the Hornings sound better with more watts than even my 8 watter. And of course there's the sound preference. I love the sound of a 45 tube and I've been seriously contemplating a Deja Vu 45/2A3 (another Audiogon-er put this amp in my head when I owned my previous efficient speakers). As for the Berning ZH270, I've had this amp for almost 10 years. In those 10 years it hasn't seen a lot of action. I also owned a Joule VZN-80, which I far more preferred. The reason why I've never sold the Berning is its just a friggin' 10lb amp! I can bring it with me when I go listen to someone else's stuff. If youre interested, it's going on the market soon.
