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.

The TAD 60...A great value and extremely versatile..can be had for around 700 used..hard to beat
If you can go a little higher, pick up that used RM9 on Agon right now. Trust me, you won't do better at that price.

thanks to all. I will also research the ones set forth in your answers.

Can anyone comment on the ones I mentioned by any chance?
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 :)
