No, not really. If anything he was trying to convince me that buying the ATI 6007 would have very low diminishing returns for my money. I don't remember too much about the rest. The conversation was a long time ago, probably a few years now.

Probably one of the most ridiculous things I've ever heard. What did he want to sell you instead?

ATI was started by Morris Kessler. Mr. Kessler has been building and selling solid state audio amplifiers since 1967. He founded SAE, one of the most respected brands in the "golden age" of stereo and he has designed for Dynaco, Crestron, Adcom, Integra Research, B&K, Aragon, BGW, Theta Digital, Outlaw Audio, Hervic, DataSat, and others.

ATI is one of the best amplifiers available at any price and will drive any ribbon, AMT, electrostatic, or dynamic driver manufactured today.

The impendence of the GoldenEar Triton as shown in the Stereophile measurements is about 5 ohms and the phase angle is about zero degrees. That's really not a hard load for an amplifier.

https://www.stereophile.com/content/...r-measurements

ATI amplifiers, like about every other transistor power amplifier (don't know about Mc's with the output transformers), have an output coil of copper wire (an inductor, positive phase angle) in series with the output. This coil is in parallel with a resistor. In ATI multi-channel units this coil is usually mounted against the back of each channel, close to the outputs. In many pictures of the inside of transistor power amplifiers these copper coils are visible.

This output inductor is installed specifically to offset any capacitive (negative phase angle) loads at higher frequencies.

There is no reason that ATI amplifiers should have trouble with the load presented by the GoldenEar. ATI amplifiers have a generally similar design to many other class A/B amplifiers. If anything, they are more conservative with more protection built-in.

Yeah, I thought so. I don't really know why he said that but I didn't make sense to me at the time but I decided not to question it at the time and decided to look into at a later time, but slipped my mind. It's not the most ridiculous thing I've ever heard. That goes to a young man at a Best Buy Magnolia that told me thicker gauge speaker wires would have MORE resistance than thinner ones.

Is the monolith 11 worth the price premium over the Yamaha ax-5000?

It depends on whether you need/want the extra power in the front 3 channels. If you have harder-to-drive or less sensitive speakers, then yeah maybe.

Being in sales myself (real estate broker), it always shock me what some salesman can pull out in front of clients to try to make a sale. Mind bending!

b curry,

I totally agree on the ATI amps.
I now have Classe' amps currently and soon, hopefully will add Atmos and then going with the ATI Amp. for the 6-in-ceiling Triad speakers.

Just been investigating this amp. The MONOPRICE site says it is not available. Out of production? Or does this amp go through recurring periods of being sold out? How long has it been since it was last available, if anyone knows? Thanks...

I am fairly certain that the amp goes in and out of stock due to availability from ATI.

Thank you for that quick response, Jeff! Much appreciated. Know of anywhere else to shop for one? -- AMAZON and AUDIOGON have nothing to show. I presume from your comment, they are made by ATI, so is there an equivalent model about the same price from ATI directly?

Actual ATI amps are better built and more expensive. The AT4007 (200 watts per, seven-channel) is a fully balanced, differential A/B and a bit over $6,000. Their AT527NC (200 watts per, seven-channel) is a class "D" amp and it's just north of $4,000.

Listen up, studios! Dolby Atmos Lite™ print-outs must stop!!

Wow! OK then. Thanks so much for your response, Dan. I just had my Plinius Odeon go south on me. I see I can still buy a new one for about $17K, but thought I would just get a smaller, perhaps back-up amp on the cheap. I guess I wait for availability...

Outlaw Audio has two somewhat stripped down ATI signature class AB amp sisters with fully balanced topology at a cheaper price. Not quite as inexpensive as the Monoprice amps, which are based on older ATI models to keep the costs down, but not in the stratosphere.The Model 7220 with 220 watts per is $2799

Thanks for the help, brotherman! Really appreciate your guidance in narrowing down the options, otherwise it is almost just too daunting to search and weigh and consider. I think this comes down to spending a huge chunk of money for what sounds the best (the Plinius), or going for something that would mostly fill the bill. I have two Odeons, the Odeon that went out of whack was just for all the rear channels, so maybe the difference will not be quite so stark with a lesser prospect? Anyway, much to deliberate in the middle of my desperate plight -- I just lost part of my world! Again, thanks Dan!

All the Monoprice Monolith power amplifiers go in and out of stock. Lots of people seem to want them if that tells you something. The two power amplifiers that go in and out of stock, or have lead-times that I see are the Monoprice units and the AHB2 power amplifiers from Benchmark. The Benchmark units are in a different, elite league (one member) of performance, and cost more. Lots of people want them as well.

Just register on the page for the Monoprice model you want to be notified when that model comes back in stock. Monoprice will send you an email when the unit is in stock. Go the site and buy the unit. Pretty simple. The units normally come back in stock quite quickly.

Monoprice has the best deal on ATI "flavor" amps.

Outlaw no longer appears to be competitive on ATI made amplifiers. For example: among other design decisions, the Model 7220 has fans, which add moving parts, internal accumulation of dirt and dust, and potentially noise, to a normally quiet and reliable type of product. It is also expensive for the value received IMNVHO.

There are dealers who sell ATI amplifiers at discounts. Do some shopping if the ATI units are of interest. It's hard to beat the Monoprice units however unless you need over 200W per channel at 8 ohms.

I doubt you will hear much difference between these less expensive amp alternatives and the Plinius and Odeons. A lot of it comes down to the placebo effect. You paid x amount of dollars and of course it sounds better (it just HAS to) when it's usually not the case.

Thanks for all that help! Really appreciate that you were willing to put the time into composing all that -- and from halfway around the world no less! (I'm in San Diego, CA, stateside). I actually did already ask to be notified by Monoprice, and regardless of what I may do about the Plinius amp that went wrong, I may just pick up a back-up to drop in if I get it repaired, then something else goes wrong. Thanks again!

Well, certainly wouldn't mean to bat a hornet's nest, and I'm sure there is something to: bucks equates to more favorable evaluation, but I've compared side-by-side, even to the highly touted Krell 5 channel of years ago. There wasn't a contest. And I've owned one of the other multichannels, I think also made by, or using the ATI model, but can't remember the exact brand -- think it's available from Southern California (but might be wrong about that).

Whether I've tricked my mind, or really did hear differences, sometimes profound, in all the forty or so multichannels and other amps I've owned over thirty years or so, is not something I need to consider any further. I've never heard a better multichannel than the Odeon. YMMV, of course, thanks so much for your help, my man, Dan!
