6550/kt88 or el-34 tube?

The speaker sensitivity 89db. Impedence 8 ohm. 13x19x8(2000cft). Listening level - low to moderate. Mostly classical and jazz. I have a sansui receiver 100w on loan. Sony scd-c222es cd player. It is too bright for my taste. I like to set up a nice system with my new speakers.

The speakers are 3 way and have 8 inch woofers. I think I go with 6550/kt88. I have just read reviews on Tube Audio Design TAD 60. I like an integrated amp and everybody seems to use this amp with a preamp. I think this can be used as an integrated and I like what I have read. There are too many choices. It's like being in a candy store and I can pick just one. Thank you for your inputs.
