thanks everyone
I'll go through this thread with Richard
I do have multi weights for the triplaner and Richard and I are going to try this first- I also have the sb with the shim under the cartridge
Richard was over and said I definitely don't have an amp clipping issue - although some of the amps power is being robbed when feeding the low freq outbursts
there are some minor warped records that cleary set off pumping in the speakers, and some other's that it's so minor (but stil probably mucking up the low end) but probably still there
I want to get all the clarity out of my setup and maybe this is the limiting factor
as for suspension - I have the Silent Running Audio platforms and stand - and a very heavy platter - floor concrete - about as isolated as I can make it
it could be a room mode - I have a 14 by 27 room
long wall setup - at listening area - null against wall and reinforced 2 feet in. I've tamed slap echo with echo busters but no low freq suppression. CD's sound fine.
Table slightly forward of speaker ports which are 3' from back wall.
Perhaps if I placed the table closer to the wall on my seperate Billy Bags stand.
I'll try covering the speaker ports as well. Ports 2 2" at bottom of speaker. Jim Salk has not encountered this before with his speakers, then again, few owners with analog
Richard set this table up with a scope and the results are stunning other than the 'pumping' problem - which is there but only strong on high voumes and minutely warped records.
If this is truly a port / room issue then I'll have to look at placement of either the table or speakers. I'm a bit concerned that a subsonic filter might just mask a problem rather than correct.
Thanks
Tom
