Looking for a first Tube Amp for under $1000


What would you turn to? I've read some very positive comments on the Onix SP3, Jolida JD-502b and the ASL AQ1003DT. What would be a good first amp which is easy to use (setting bias)? I mainly listen to rock and jazz and the amp would originally be played through a pair of Bose 301-IV speakers.

i use a modified 502b that i bought from an agon dealer. easy to bias, other than unplugging outputs to components it is a 2 minute job at most. new ones have built in biasing option i believe plus remote. has worked great for me and has 60 wpc which is plenty. fwiw, if you are serious about sound you better trash those speakers before you can appreciate any decent amp, regardless of tube or solid state. i hope you are already aware of this :)
Veroman,

oh yeah those Bose speakers will have to go sooner or later but one thing at a time. I'm strongly considering the Onix SP3 because of the offer that comes if you buy their combo amp + speakers. I'm guessing those speakers are probably better than the Bose.
Over all the new economical Chinese manufactured tube amps showing up on the scene today I would recommend a restored Dynaco ST-70. It will meet your wattage needs and give you a sound that few new tube amps will approach, very musical. They have legendary iron and with today’s modified power supplies and caps are excellent. There are several very reputable builder/dealers on AudioGon worth considering. I concede that buying a new retail product is virtually a "no brainer" yet, with a little research and education there are IMHO some greater Hifi choices out there than these. You get what you pay for and that’s not just in “cash” currency. LOL

Happy Listening!
Thanks R_f_sayles! Dynaco ST-70 is definitely one of the amps I've also had an eye on. I see them on eBay a lot but I'm nervous about the quality of the mods and refinishing. I guess I need to figure out who are good resellers if I'm going to consider used amps.
