Vandersteen Model 5, 5A 5C Owners

I am interested in hearing from Vandersteen Model 5 Series Speaker Owners:

1) Have you had your speakers set-up with the analyzer program/test tones?

2) If so what improvements did you hear?

3) What amplifier(s) are you using with your model 5s?

4) Do you prefer tube amps or Solid State Amplifiers and why?

5)  Are you using the speaker spikes?  On carpet, floors, etc.

6)  What speaker cables are you using?  Bi-Wire or Jumpers?

7) What other speakers would you consider auditioning at this point if you wanted to change speakers?

Thanks and Happy Listening.
