IC's between Power Amp and Pre Amp


I am looking for suggestions about IC's to go between Musical Fidelity A3CR Power and Pre Amps. I am looking to upgrade to approximately $300 to $400 level. Any suggstions or warnings will be appreciated. Thanks

What speakers and speaker cable will you be using with them? Is there a certain type of music you listen to more than others? And, what aspects of sonic performance are the most, and least, important to you?

Are you using the copper Spectrums for all connections? Did you use the X-2s in the same way - between all components? I was thinking of trying the X-2s but too many return charges. In what way did the Spectrums surpass the X-2?
Thanks for any info.

Paul, hi.
I am now using the Spectrums for all connections.
At first I had one pair each of Spectrums, Quattro Fils and X-2s. I tried each pair with each other pair in each position. (Sorry for the awkward phrasing: it's late).
I found the X-2s to be tonally "light" (less full bodied than the Spectrums - not that the latter are in any sense thick or slow: they are in fact neutral and quick). This was the only drawback I found to the Oriteks.
Both ICs are highly transparent and resolving of low level detail and ambient info.
Will try to post a review within a week.
