I recently gave my WES - originally El_Doug's WES - over to Jack for implementation of his latest "revision".
Something to do with 4 filter chokes.
As far as I know, replacing the old ones with upgraded new ones.
A $750 job.
I had asked Jack to look into the inside of the amp while doing the revision to see if there was anything else
that could be done to improve its performance.
Jack's answer: there was nothing inside which needed upgrading.
But he did move a few wires around.
I had spoken to Jack about the fact that I found the Stax SR-007 mk I unlistenable through the WES.
Too dark for me to hear the full range of highs present in the music - highs which were noticeable to me through
other set ups - even with my very pronounced hearing loss in the high frequency range.
Jack said that the 007 was a dark phone, but that a change of tubes might help some.
When I got the revised amp back home, I discovered that, even without any tube changes, the SR-007s
were now quite listenable.
The highs were there and, as far as I could tell - please take into consideration my paucity of critical listening
skills and substantial hearing deficit - nicely balanced with the rest of the tonal range.
I am writing this report so that others who have the WES may have an idea of the value the new revision may
make in improving their enjoyment of the SR-007 with the WES amp.
Particularly since there have been reports on this forum indicating that several WES owners had found these
phones were unnaturally dark with this amp.
(And I haven't found a discussion of this)
I am wondering what changes others who have done this filter choke revision may have found in the sound - in
general or in whatever respect - of the new improved WES.
