Which has a greater effect on music,int.amp or CD?

then you will probably prefer the YBA line, cd & integre. Also they do synergise VERY well. I have found the YBA a better, if more expensive, proposition. Especially when listening for longer periods of time -- i.e. living with the components. Good luck!

Thanks for answering, Matty. I was just checking to see if there were any confounds to your previous statement.

Joel - IME, warmth and detail are not opposites, they can coexist. When under a certain budget though, they are often opponents.

I am pressed for time so will have to make my comments brief.
I think both the cd player and amp will have equal influence on the sound, but the sound of each should be balanced for optimum voicing.
I am a former owner of an ARC Complete Int Amp.
If by "warmth"; you mean the natural reproduction of the timbre of instruments and voices (without some form of electronic glaze or haze), then I do not think the ARC will do it. You may disagree so by all means listen to one.
That said, I believe there are few ss amps, short of something esoteric and expensive like Rowland that will do what you wish.
I would strongly recommend that you at least listen to a tube amp before making your final decision. It doesn't have to be an expensive tube amp. If money is an issue and you still do not want to try tubes, I would suggest getting an NAD integrated amp and getting a better cd player and Harmonic Tech cables. The NAD won't be quite as transparent as the ARC, but I think it's tonal balance will be more to your liking.
Listen carefully and have some fun. This is supposed to be fun.

Matty....I doubt having both the Complete CD and Amp is "too much". They were designed to go together as unit. If you like the YBA sound, then they should be perfect together.

HD- the 'truth' of the recording can turn in to lies by the time the speakers get a hold of the signal. Ever play the game, telephone? It is more complicated than this (as in this thread), but good components lie less than bad ones. Good components play telephone better.

It may have been a bad idea to post this. I am not debating.
