Xtant or Arc audio??
Percy, Retro and the rest,
Other than subjectivity, why do you think Mc is better than either Zapco, Arc or Brax? Can you hear the difference? You opinion is merely subjective, trust me. If you beg to differ, I suggest you contact Richard Clark (of Autosound 2000) and take his challenge and let me know how it goes.
As for build quality, Zapco is built like a brick $hithouse. The damn thing is over engineed all the way. As for Zapco being thin (according to Vel) in the sub frequencies, call John Borges over at Zapco and show him in print (I haven't seen what was typed) b/c I think he will have a nice lawsuit for the libelous statements......

Ira,
Too many "loopholes" with the autosound challenge. No test tones and no modded amps as well as a whole bunch of other "no-no" stuff involved. My stuff would be instantly disqualified as I've changed out the parts internally. You can do a search on the topic of the autosound challenge- it's somewhere in there. As for Velodyne, don't go too fast on the lawsuit button! They (Velodyne) tested the amps in real life situtations and the Zapco didn't perform. It's documented in their instructions. Though they didn't say which amp was tested that was from Zapco.
Now as for the numbers, Mc is THE only company that I've seen that will do better than their specs. Auto Sound & Security as well as Car Stereo Review has said this in their full lab reviews of the Mc units. Even Brax (though they are great amps) didn't fare up to the lab/real life measurement vs their "claimed specs". Since '96, Mc is the only company that I've seen that will conservatively rate their amps. Reminds me of the old Buick GNX...we're only good for about 240+ hp. When in reality it put out much more than that!
If you have any amps that test AT or BETTER than their claimed spec, let me know! I had high hopes that Brax would be able to do it, but unfortunately, it didn't. It's still a great amp, despite the advertising.
"Do what you say, say what you do". So far Mc has met up to that challenge as well as Velodyne. Less than 1 percent distortion for a sub throughout it's operating range - and a large format British magazine tested it to be true.

Something with not enough amplification below 30hz....Even if the Vel could run with Zapco I'd still stick with Mc. Very high channel seperation numbers as well as signal to noise ratio. I have still YET to see an amp that will beat the Mc on channel seperation and real life signal to noise/distortion numbers.

In actuality, Zapco is too strong down low and, additionally, due to the way the Velodyne system works, it is incompatible with Zapco b/c of its inability to handle the input signal. (had a cell phone conv. w/ Bill while I was shopping with wife this weekend and the rapid rate @ which my wife was spending $$ distracted me from the conversation) If you want all the techincal mumbo jumbo, call Acevedo at 732 291 8808
Now, if McIntosh is so damn good, why the need to mod the amplifier? Seems many a world champion has taken Zapco straight off the shelf, installed it in their car and won world finals.
Lastly, if Zapco amplifiers "don't amplifiy the low frequencies well enough", why did Earl Zausmer choose Zapco amplifiers to power the subwoofers in both of his BMW 5 Series installs, both vehicles winning the World Finals when it really meant something to win the IASCA finals........ Remember, his car was in "Time" Magazine. Also, I am using a 9.0 for sub (full range class D amplifier) and did not boost any frequencies in the sub at all, as a matter of fact, had to cut all sub frequencies (sealed enclosure) and the car still is capable of low to mid 140's (on my SQ setting, muting the mids and highs) if I let it go there. Only two 12" woofers in a sealed enclosure built for SQ, go figure.

Actually, according to Zapco literature, independent testing results of Zapco amplifiers (in general), and Bill Acevedo of Sounds Impossible (shop owner, builder of numerous IASCA world champion and/or top 5 cars (at finals) tuner extraordinare, Zapco dealer and an individual who has experience with Velodyne subs in cars), your statement about Zapco and Vel being like oil and water is 180 degrees out of phase.

***Remember what my system goals are - if I can push the limits, I will in a SQ system. Anything that is really good can be made even better. It's just like owning a Lexus...if it's really that good "out of the box" then why bother to modify? Truth is, even the "best" electronics can be made better. They just have to do it within a price constraint, while we, the final consumer, can bump up the performance if we choose to do so. A simple mod that makes quite a bit of difference...Black Gate Capacitors. Cleaned up the processor that I'm using by ALOT - quite obvious to the average joe too. You can ask Peter Lufrano of The Autophile about this one.

I do push the limits of SQ in my car - ask Manville Smith of JL Audio who listened to it at IASCA finals and rated it higher than 3 out of 5 expert cars (0.5 points from another expert car) and better than all the pro cars he listened to but two of them. I think he is fairly independent (hell, I don't even use JL audio products and some of the other cars he listened to did and, were either presently sponsored and/or previously sponsored by JL Audio and I rated higher)
***They do this in Japan also. Many McIntosh amps running around - very few Zapco. From what I see, Japan is much more picky about sound quality and the extremes.***
Japan has vastly different listening criteria to the US, I don't have all the time in the world to get into it but, trust me, they set their systems up differently and, as a result, are looking for different listening cues than we are - dont' believe me, ask Harry Kimura

His attitude has nothing to do with his amplifier choice for the low end reproduction. Don't cloud the issue. As for his choice of Milbert, Earl was a very different kind of guy and his Milbert was just an extension of that. As for judges in his back pocket, get real. I competed against Earl (in Zone 3) for two years, 30 + shows, and then saw him at numerous other shows for years after. Spoke with him all the time too. Used to be very friendly w/ Earl. He didn't own any judges, his car just sounded that damn good (from one seat). BTW - you do know that "warmth" in sound is distortion and/or coloration, right?

Percy,
Send the info to Ira Senoff c/o Mail Boxes Etc 302 Mercer Mall, Lawrenceville New Jersey 08648. It is my brother's store. Let me know when you are ready and I'll get you an amp or two to play with - or, if you really want a challenge, go to an IASCA competition in your area (where are you living?) and let me know how you stack up.
Ira

Hi Ira!
I'm trying to get a Brax (Platinum) amp from Peter Lufrano to put them up in a match/comparo but he hasn't gotten around to answering me. He knows it's a writeup for Clublexus. It'll be a subjective listening test between Mc, Zapco and Brax. Should be interesting! All high end stuff.
I put the manuals away somewhere...I forgot where! But I will keep your address handy for mailing in case I find them. You know the old saying...when you're not looking you'll find them.
Peter sent me some info on the Vel correction circuit. I'll look for the email and PM it to you.
