Would increasing the gain in the amp give more weight to the sound? Any negatives?


I have an integrated amp with passive preamp section and I feel that the sound is not full-bodied enough. The separate phono stage has 42db of gain and I use MM cartridge. When I play cassette deck, the sound is just right in this respect.
I talked to the designer, and he said that increasing the gain is theoretically possible, though time consuming.
And if I do want to increase the gain - by how much? The amp is 120 watt/ch/8ohm, speakers are 89db efficient, 8ohm.

Try reversing the polarity of your speaker cables. You might discover that your system is reversing the polarity, and by flipping the speaker cables, you suddenly hear a richer sound. My system needed it. And, the one before that did too.
Genez has hit on a good point there, but it could be just one channel that's out of phase with the wiring in the cartridge/arm/or even the PH1. Just try reversing the polarity of one channel first.
