Re: Bypassing Output Caps in Preamps

Assuming the current output coupling cap is properly sized I don't think paralleling (aka bypassing) with another cap will make a significant enough different in the bass.

"Bypassing" usually means that you are paralleling the existing cap with a relatively small cap, maybe .1 of the original value or so. This is done to help out the high freqs. Even doubling it to move the -3db down probably won't do much assuming its big enough to start with and it may actually hurt - its entirely possible to have too much IMHO. Whats the input impedance of the next stage and the output impedance of the phono pre?

IMHO you may be able to get enough of an improvent to suit your tastes by *slightly* tweaking components in the RIAA curve circuitry to tip the lf response up a db or so. Try it and see. Another variable is the cartridge - some do LF subjectively better than others in any given system, just like tubes can. Maybe this is worth exploring too. -jd
