No Pain No Gain?


I am wondering if anybody has some useful advice as to the true function of gain settings and their sonic effects other than volume control. I have a ML 32 which has the possibility set set gain for each input at 0/+6/+12/+18db and an EMMlabs CDSA-SE cd player that has a high/low gain option (I believe +14/+18db). What would be the optimal setting? Or is it totally based on personal taste, or is this functionality only really for matching volume levels for several differing sources?

Any helpful comments on this topic would be greatly appreciated.

Mr Tennis, I'm no bodybuilder, but they would argue that the opposite holds true for them, no pain no gain :-)

But the Emmlabs unfortunately doesn't come with a no gain option. The lesser the gain, the higher you need to turn up volume, the more you get distortion and/or noise. The best result for my system for now is high gain setting on the CDP and 0db or 6db on the pre-amp, depending on the CD recording. Great that I can change that easily by remote.

If so, there's something definitely wrong with the S/N -- the system noise floor is veru high, or gain stages, or...
I strongly suggest you check it out.
As far as the ML No. 32 is concerned, I don't think that either the gain setting or the input offset affects the sound. I believe that these controls are used to match relative levels of each input. I don't think the different settings engage different number of stages of amplification; they just set the selection of the resistors in the stepped attenuator. So, for any given volume level--whether set by going +6 on the gain and -6 on the offset, or just increasing the volume knob by 6db-- the same set of resistors are switched into the circuit.

By the way, I do miss the incredible flexibility and terrific implementation of volume/balance control of my Ref. No. 32 (currently relegated to back-up status).
Greg, I was not referring to my system's noise floor, which is very low. Only if you put your ear on the tweeter and turn the volume past 3 quarters you start hearing a little hiss. If you sit back 8 feet, you can't even hear it anymore. I was referring to theoretical S/N. Anyhow, I don't think the ML is faulty in any way.

Thanks Larry for your explanations. You're right about the matching of inputs, and currently I have only one. So much of it has to do with my perceived comfort of volume level and where the "dial" sits.
