I the newbie have a question critical to my developing system.

I have a pair of NHT ST-4's and am looking for a good, powerful amp, maybe adcom, to match it. Currently I have a tecnics tuner/receiver/amp (yuck, spitter, gag, etc) .. I am considering keeping this and using it as my pre-amp, since it does have an A, B or no speaker option.

That being said .. what kind of a qaulity hit am I going to take using this technics as my pre-amp if I have good speakers and a good amp to go with it?

I don't understand the purpose of a pre-amp and that is of certain -partially- why I am asking this question.

I'd rather have an adcom gfa-555 with a cheap pre-amp setup than say a gfa-545 with an adcom pre-amp, does this strike you as logical?

Thanks- John
