Dynaco PAT 4 Pre-Amp ....Why is it Bashed??


I just bought this Dynaco PAT 4 Pre-amp.
AMP : Paired it with Emerald Physics Class D  100.2 SE amp
and 
SPEAKERS:  Mark Audio full range P12 
 I am puzzled why  there are so many negative comments  being posted regarding this pre-amp sounding harsh and bright.
It sounds good to me...clear and detailed.
Any PAT 4 Users .....comments?  ( in stock condition only)
thank you

The PAT-4 was first introduced as a kit along with the Dynaco 400 SS amp. I built many of these on the side while i was working at Bendini building tube amps and i sold them as complete units. I remember back then that depending on who did the build that units could sound different from each other, i estimate that i built and sold over a 100.

Personally i never liked the way they sounded they had what i considered what was to become the classic SS sound that we lived with for several decades.

Anyone  know anything about Frank van Alstine? I have a chance to buy a Pat 4 restored by him and am wondering if that rings a bell with anyone here.

I am tempted to buy a Dynaco PAS3 and ST70 built by Kenny Russell.  Kenny's units are beautifully built and to the extent you can tell via computer, sound great.  Check out Kenny's webpage at: GetDynaco.com  .

This reviewer is very low key and I appreciate his reviews.
