accuphase compare to mcintosh

Fremer might've got too excited and exaggerated it a little but I would think that most likely that Greek thing is really great even if they use junk grade parts; probably not. And his vote is not quite like everyone else's.
You say NASA grade parts? NASA itself has so many failures in addition to successes that you know what? I don't want similar grade parts in my amp. Military grade would do just fine.

Audiozen,
Does NASA use a lot of audio parts? To NASA, NASA-grade parts means reliability, not necessarily sound quality, and the best grade of parts is effectively a certification of existing processes and manufacturers, establishing provable reliability and consistency of manufacturing processes and supply. If you read NASA parts procurement guidelines, you will find that they in fact specify use of parts up to and including 'mil-spec' parts of a grade called MIL-STD 975 Grade 1. If you care to read that giant PDF file, you will find capacitor specs starting about 20 pages in.

I think, if you dig through both docs, you will figure out that any audio manufacturer which went through the process of finding good-sounding capacitors and matched them would probably end up with better-sounding and more appropriate capacitors than those taken out of a NASA engineer's parts box. If you read the guidelines and the MIL-STD 975M file and come up with different analysis, I'm happy to be corrected.

The term NASA grade absolutely has to do with the quaility of parts and the rigid extreme conditions they can experience, it does not mean the same parts that are used in control panels in space ships, but the type of dielectric materials used in transitors, capacitors, circuit boards and their skin material. When combined, these type of materials and parts are much more efficient when dealing with severe heat and severe cold and have much lower defect rates and higher tolerance values. NASA is a term that reflects the type of high quality over the years that the military and aerospace apply to parts that result in the highest quality for communications, sound and observation. For example, Solen, Wima, Blackgate and Vishay are considered NASA grade quality and classification but are not used in military or aerospace programs but for high end audio products only. Again, its a classification term that applies to quality only. Besides, we are getting off subject, this thread is about Mcintosh and Accuphase.

IMO, being a current McIntosh amp owner and having listened to Accuphase numerous times.Accuphase hands down,no comparison.What I do like about Mac is the re-sell value on the secondary market.

So what.

He gets one vote like everybody else.

Not that I agree one way or another with anything that MF has to say, but I would say that not all votes are created equal. Listening to many pieces of equipment over many years is a valuable part of having one's opinion matter more - in theory; though it does leave open the question of whether you have the same listening tastes and preferences, but all things being equal, depth of experience and exposure does lend more weight to a person's opinion. In fact I value your opinion to the extent that you have many years of experience with various pieces of gear --- that is worth something.
