Jadis amps and pre-amps still competitive?


How does Jadis amps (Defy7, JA 200, ect.) and pre-amps (JPL MK2, 80 MC), compare with the more popular amps of today from VTL, LAMM, and Audio Research. You don't hear much about them anymore. I remember that they were highly regarded when Mr. Victor Goldstein was the importer.

Treja, I have a Defy7 MKIV and would like to try the JJKT88's, doees the "JJ" refer to the brand of the tube? Or is it part of the designation of the tube, as I never heard of "JJ". Can you please clearify. Thanks.
How would something like the Jadis JA-200's compare to Audio Research 610T or CAT JL3 ?
