What to update first: pre or power amp?


So, I am seeking all opinions on this (if you read the Asylum you will see the same thread). I am looking to upgrade the sound of my MartinLogan Aeons by going from Rogue Magnum (66 and 88) to the CJ Premier 17/140 combo. However, I am not sure I can do both at once, and my only local CJ dealer doesn't stock the 140. What do you think would make more of a difference in the system: upgrading the pre from the 66 to the 17LSII, or upgrading the power amp from the 88 to the 140?

Since, in my opinion, the amplifier is by far the most underrated component in any system, I would ensure that that part was taken care of first and then match everything else to the amp.

-IMO
I am in the exact opposite camp as Stehno........Oh well such is life. The pre-amp has always had the biggest impact on my sytems performance, all things being equal, except for perhaps the speakers. However, having said that either component you upgrade (amp, pre-amp) is going to have a pretty significant impact. You mention your dealer does not stock the 140 does he/she stock or have as a demo the 17 and if so will he/she let you bring it home for a demo. No disrespect intended to Stenho we all have different experiences.

Source first. If you don't have a good pre-amp, your amp and/or speakers (no matter how good) cannot make up for information that does not get to them. This has been proven, although some will undoubtedly disagree.
