Audio hobby is a journey. If you agree to that, it may be a good idea to find an amp that allows you to experiement various things of a tube amp. Then you can gain knowledge and develop your own preference. Treat it as a stepping stone to reach your audio nirvana.
If you agree with the above idea, I would recommend the following requirements for choosing your tube amp:
1. Manual bias: This is a key feature that I look for in an amp. In fact, my Counterpoint hybrid amp allows me to adjust the biases of the output bipolar transistors too! You want to experiment biasing the output devices at, below, and above the recommended value. For my KT88 monoblocks, I'd like to adjust the biases at 15% below the recommended value, which gives me more delicacy and finess.
2. Ultralinear or Triode switch: It allows you to adjust the output tube mode, ultralinear or triode.
3. Enough power: it allows you to try various music. The bass guitar in Jazz music does need power!
There is a Rogue M120 that is just listed for about $1K. It may be a good start for your journey.
