If it’s broke fix it!
Hi,
I want to use my newly acquired QUAD 34 - late grey example with CD input - with an AT VM740 or 150sa, which share a body.
I normally use a 33 preamp and the sound is great, bright and detailed as I like (405/ESL).
Same with my other preamps, valve or transistor, there’s little difference.
Now the 34 makes LPs sounding dull, as if treble was partly erased.
By default the load is 47k/200 pF (styroflex).
I tried to reduce the capacitance by just lifting the cap, with the cable from the turntable being about 100 pF.
A tiny bit better but still veiled and therefore boring. Even bright records are dull.
CD and radio sound fine, however.
Any advice welcome
