Your dream has come true with the new model

@@sheldonunrau8818 I guess you are referring to the MC451?

@@adrianlow2114 No what you said is not wrong but you are only talking electrically and leaving out acoustics part of it. A lower impedance places more demands on the amp and yes draws more current. If one has some low efficiency 2 ohm midrange drivers yes those will draw more power to drive. My statement is more of an all things being equal statement. That link I provide will show what I'm trying to say if you go read it. I also have books here at home on this. Each time a given frequency is halved in order to play at the same volume cone excursion goes up by FOUR. (yes four not two) This is one reason woofers need to be larger. Power requirements as we go down into the low bass goes up (by a lot) and like wise as we go up into the midrange and highs the power requirements go way way down. Trust me that 75 watt mc275 would be more than enough power for most speakers but if the crossover is say around 350 - 400 hz and up probably not only has power requirements dropped by magnitudes (remember the cone doesn't have to be pushed as far) but the amp itself having all the work below 400hz removed suddenly becomes much more powerful because higher frequencies are not having to ride on top of lower frequencies. Really the impedance factor you brought up is a different issue and nothing to do with this.

Arian sorry I'd like to explain better but have to go to work. The thing is it isn't just electrical like you said. Mechanics of the woofer come into play and other things. It takes more power to push a woofer further as frequencies go down. Also the midrange amp ACTS like a much more powerful amplifier now not having to do the lower frequencies because all higher frequencies ride on top of lower frequencies hence limiting power to what ever the demand of the lower frequency signal is. Please follow the link I provided in my first reply.

@@adrianlow2114 I don't know if you can run across it anymore but I just picked up a book off my bookshelf: "How to Build Speaker Enclosures" by Alexis Badmaieff & Don Davis. Copyright 1966 so I'm showing my age here. This book has a section on power and cone motion with frequency which is where I get some of this. They wrote this a long time ago but still not wrong.

​@@adrianlow2114 There are a number of reasonably priced, efficient speakers that are very efficient. I have an open baffle, 15 inch full range speaker that works and sounds awesome. It is 97 db efficient and I drive it with a 2 watt, high quality amp. It is much better sounding than the electostatic speakers I used to have.

Art Anderson I’ve been looking for a suitable open baffle speaker to replace my decades old mirage m3s. What open baffle speaker do you have? Thanks.

@@Scottlp2 It is the Caintuck Audio Li15 speakers. www.caintuckaudio.com/Lii_15.html.

Adrian Low thanks Art and Adrian

I would agree with you. For that kind of money, I would expect uni-block construction as well as point to point wiring for much of the internals. I was looking at the Pathos Logos amp for 5K which looks to be better build quality as well as has point to point wiring and larger capacitors. My problem is that they are based out of Italy so good luck with reasonable service if you need it. At least McIntosh is American and has a great reliability record, stands behind their products, and would seem to be fairly easy to service.

I remember when I got a MC 275 at a garage sale for $60. 2nd best deal in audio I ever got.

Rogue Pharoh integrated amp is excellent, it's 3500 USD build like tank, awesome sounding amp comparing to MA352

@@babydove I also looked at Rogue, my only concern is resale value. Will continue to consider. Thanks!

Tube amp i do hear it is warmer And round

How is the mc611 driving your stella? I opted for a different choice, i am having the focal maestro driving it wirh the dagostino progression and i got the 2 focal evo subs which are the one used in stella.

nezar le pro The MC 611s work wonderfully. Just interested in improving mid range and highs if possible.

Yeah...I feel for ya' man. I bought a new chainsaw and mine went bonkers. Guess she couldn't understand the necessity of limbing old trees that had already damaged her car to the tune of $1500.00. Oh...and if you want stereo...you'll hafta' buy TWO of those amps at $17,500 = $35,000 Ooohh...gotsta' win me a lottery.

In fact no, its 35000 since you need 2!!!!!

@@Wised1000 Didn't I just say that?

@@Ian-iu2tl 🤣🤣🤣

$35,000 U.S., drop in the bucket for a millionaire. They wouldn't bother with these, they already spent over $350,000 U.S. on McIntosh's 1200watt mono blocks and McIntosh's top speakers. You have a very hard time imagining what it's like to have millions of "dollars" don't you.

@@Mark-lq3sb -- Millionaires don't get that rich by throwing away $$$. Maybe the silver spoon types do that, but not the folks who worked their way up who I've met. Moreover, the Kii Thee will outperform any all-McIntosh system -- but of course if you look at Mac stuff as an investment, it does tend to appreciate and lasts forever if you take care of it, so if performance is secondary to resale value and status/prestige I see your point.

I do agree with you, I will never afford anything close to what this equipment costs, or even a Kii Three system for that matter. However in the ultra high-end world, these amps are actually a bargain... I know that sounds crazy, but you can spend $250,000 and more on a pair of monoblocks. I am curious to see how they perform, because honestly this is a really good idea that Mcintosh came up with.

@@chadisrc -- My hope is that some time before I die (I'm 72) lower-cost implementations of the Kii Three's innovations will show up, e.g. something less lavishly appointed, with PBTL-configured TPA3255 amplification instead of pricey NCore modules and analog-only inputs would be fine with me.

@@editorjuno A super headphone setup can be pretty great for sub 10k. Look into 'ear speakers' like the Raal SR1A

Misleading? Buddy, you've been involved in too many crash tests.

That's my favorite type of night lights.

@@TheMrgonzalo05 I have an old Mc amp. I should sell it on given that it has been surpassed. But, God, sometimes I just sit there with it on as it's just such a thing to look at. lol
