Audio Research Ref: CD8

I just sent my CD7 away for the upgrade. I think my player had the previous "lifeless" upgrade that was referred to above where a raised board was installed to hold the two 6H30 tubes. Perhaps a version 2 from the original. If this is the case, I cannot wait to hear the latest version and the associated improvements on an already great player. I will post my findings when it returns. Better sound and more reliable? Who could ask for more from a great company like Audio Research. I, for one, say continuous improvement is a good thing....

Mbudinich, my player has the same kit of yours. Did notice something too: I have days that the player sound great in other lifeless. Does the same happened with you?

Ossocao, I don't think I have experienced days where the cd player sounded better than others or any inconsistencies. Perhaps there is something else wrong with th player or elsewhere in the audio chain. Have you received your upgraded player? Has this corrected the issue?

Hi,
I have fitted myself the two tube upgrade kit to my old CD7 and did not find it deteriorated the sound - truth is it did not change, compared to a good set of matched 6h30.
Later a close friend also had it fitted to his player by the distributor and considered it an improvement. As he was listening to an unit with defective 6h30s in the power supply immediately before it is not a good case.

Owners using RCA units immediately noticed the hum noise when the tubes were not matched, people using the XLR output only noticed a much poorer sound.

My CD8 is still burning in ...

Can anyone post pics of the upgraded CD-7 with 5881 tube installed ?

C'mon, don't be lazy ! Support audio community !

I have already done my part and posted images of the CD-8 ...
