Isn't this the market they are going for, not those of us that only dream we have that kind of money for one component.\:\(

Eric, a lot of manufacturers don't release the rise time data because its more definitive than slew rate which some manufactuers can fudge. Axiom's rise time is very high at 8 microsseconds to reach 500W. Also keep in mind not many amps can reach 500w. So the fallback is slew rate which is much lower at 50v/microsec in the Outlaw 770.

Er... just to clarify... "very high at 8 micro" is negative, suggesting that it is commonly UNDER 8 microsec. Was that what you meant or was it the other way around?

Actually, they are very consistent. Most (if not all) of their products is anywhere from 30-60% of the price of their competitor for an equivalent product. With the capabilities of this product (working out of a single 15A circuit), it IS less or around half the price of those McIntosh and all products .

Thanks for the catch Eric. I meant to say the rise time is "very FAST at 8 microsec". Rise time measures how fast the amp goes from 10% of rated power to 90% rated power. It's like accelerating a car. Other amp manufacturers don't usually post that stat so slew rates are more common. I mentioned in the OP that the Bryston has a slew rate of 60V/microsec and the Axiom slew rate is >80V/microsec, while the Outlaw has only 50V/microsec.

Excellent, John. As you may have surmised from other posts, the arrival of the A1400 on the market is about to make me accelerate my 2-year plan for a high-quality power amp fairly soon (because the A1400 is less that half what I would have had to pay for what I want with even more power/flexibility).

So it is nice to confirm that the A1400 is as good as I thought it was, based on those data. Since I only listen to classical music (SACDs/DVD-a in preference) most of the time at -7db, or even sometimes at "live" volume, consistency, speed and power are my most important parameters. That is why I can't wait for that 700W/4Ohm and 8 microsecond!

It's still is a LOT OF MONEY!!! But, I am the type that buys once for a long time, so it is not too bad... \:\)

Eric. You are going to love how the A1400-A makes the music sound more natural and transparent. Classical music tunes are usually the most carefully engineered recordings with the highest dynamic range. If you want to "be there" the way the engineer intended, you need to be able to cleanly reproduced those peaks and transients. We keep talking about dynamic headroom and I remembered an excellent article which Alan wrote that I highly recommend reading again. I especially like the way he describes how important dynamic headroom is when reproducing piano and orchestra.

I have the Outlaw 770 and the A1400-A sitting one on top of the other in my HT right now. I have gone back and forth and the A1400-A is more revealing, with more transparent highs and slightly tighter bass.


When you stated that the Axiom sounded more trasparent and detailed than the Outlaw, what volume level in dB were you refering to? Or is that true at all volumes?
