Pull your boards! ALL of them!
Posted by: lp12 on 23 February 2004
Recently upgraded, 32.5/Hi-Cap/150. Replaced 150 with a pair of 7 yr old 135's.
I was floored by the increased level of detail BUT was agitated by the thinner sound I was getting. The bass went deaper but was less satisfying....
I was beggining to worry that the 135's were just this way (I have heard that they are not as warm as the 250, and I can say they are not as warm as the 150, 200 or 250/2 which I tried). Out of panic (ok, very mild agitation)I decided that I would upgrade the two boards in my 32.5 that can be replaced with 72 boards. I opened the case to have a look at them, (I am inquizitive)the old boards that is before calling Naim to order the new ones. I then put the pre back together and thought for the hell of it I would try the Tape input...
Tape input did not sound as clean, BUT it was a a bit more pleasing in that it was not as bright..... I then went back to the Tuner input and the clarity came back AND the lower levels of brightness were still there.
I opened the pre again and pulled all the boards on and off about 5 times each and then re-assembled. BANG! Brightness be gone!
This may be old hat to some but I would ABSOLUTELY recomend (for older pre's) to do this as i suspect it cleans the contacts much like disconecting and reconnecting DIN's does.
