And perhaps the damping factor of ma7200 is not very high due to the autoformers, don't you think so ?

MC generally are not High Damping Factor amplifiers
Do you think it will be a big problem with CW IV speakers.
I have also read that the damping factor was not high on this McIntosh amp and that to handle bass frequencies, it is better if the poweramp has a higher damping factor.

Sometimes it's not because it is beautiful that it sounds good 😜

Please, no fight ..
I only asked what amp for my CW IV.
I have tried some, and each are different .. Valve amp or SS.
It's a reality that our klipsch speakers do not need much power (because of a high efficiency) but sometimes, woofer (15 inch) need a little more power that some tubes (valves) can give. It's my opinion. I have tried SE 300B amp, push Pull EL34, those amp i have are not enough powered or better said, do not go to wide in the bass frequencies ..
My integrated amp Audio Analogue Maestro Grand integre drive the CW iV much better.
If i ordered a McIntosh MA7200, it's also to see the two big blue eyes and to test my first McIntosh .. I have listen here and there that Mc amps work fine with Klipsch speaker. I think, it can't be so much people that make bad experience with Mc Amps .. they are not all liers ..
But please, no fight. Everybody has it's own ears .. and we do not all like the same sounds ..
Someone i know has CW III with Air Tight tube amp, and another with KT88 Jolida, and it sound very good ..

it will come by ship (it's too expensive by plane because too heavy).
the dealer had only one left, i ordered one hour too late, he has to import one other for me.

From France.
I will get it in two month if not delayed.
It will arrive near christmas day

yes i have some amps ... collected during a few years (over 40 years).
I also have Proton AA2120, Hiraga 8W class A Monster (DIY), Yves Cochet AL2 (EL34 PP - a french tube (or valve i do not know how you call it) amp maker).
I tried Topping D Class amp, a little Musical Fidelity, a SAE 2200 power amp, a very old NAD 1020 preamp and some more.
Over 40 years of trying to find the good sound ..
In speakers, i had Onken with Iwata horn - jbl 2440 drivers, jbl 2405 tweeters, Fostex FT90h, T925, FT65, .. B&C drivers, Atlas sound pd-5vh when i tried to make La Scala clones, ect ect ..
now i am trying to have a simple and good working hifi system .. with Cornwall IV speakers, McIntosh amp, an old Sony CDP-X7ESD cd, a little Logitech squeezebox Touch streamer, a Topping dx7s dac that i will not more use when i will receive my McIntosh MA7200 amp.

i never had McIntosh amps .. it will be my first one .. and where i am living, no possibility to ear or try one in a shop near to me.
So i decided to order one, and i will see or ear what it is able to reproduce sound on my Klipsch CW IV speakers ...
Now, i have Hiraga 20 W Class A power amp with Kaneda preamp, or Audio Analogue Maestro Grand Intégré amp, or Vincent SP991 amp with Vincent Sa93 preamp .. or a very old 300B Pro (maison de l'audiophile) amp ..So i will check if the McIntosh is better than all the others.
If not, i will have lost over 10000€, more than 11000 $ !!

Manual says 40 over a wide band which is fine in the real world.
I have thought it will be more than 40

Do someone know the damping factor of a McIntosh MA7200 ?
i wanted this kind of amp because they have output transtormers
I also have 300B valve amp, sounds good but not in the bass section.
I have a french EL34 PP valve amp, sound a little better in the bass.
I know that speakers with high efficiency do not need much power .. all of my amps sounds differently.
Now, i just wanted to try a McIntosh amp .. Have i made a bad thing by ordering such an amp ?
-
Yes Shakeydeal ... i ordered a MCIntosh MC7200 .. i hope it will sound good with the CW IV .. even if i do not need 200W power amp.

i have two models of K77 tweeters. One with a round magnet, the second with a square one ..
Are these tweeters very different ? Which is the better one?
What is the difference between these ? year of product certainly but what other ? Which is the most recent product ?I have numbers on both .. one pair has 824 9946 743 on the other 824 0137

If so then why T4A which has 1 dba higher dumping was used instead of the T2A autoformer?
it will be hard for me to find T4A autoformer ..

Please, could you tell me which horn you use with the de120 driver ?

Plane wave frequency response: 110 - 4,100 Hz

The driver also provides terminals direct to the voice coil. The units are finished in gray, baked epoxy and mounts to large format horns that terminate in standard 1-3/8"-18 male coupling thread.
Specifications: • Power rating: 40W @ 16 ohms • Plane wave frequency response: 110 - 4,100 Hz • Sensitivity: 110.7 • Impedance: 16 ohms • Voice coil: 2" • Dimensions: 5.125" H x 4.375" W.
Highlights
- Powerful driver for large format horns to deliver powerful sound reproduction
- Extended frequency response to create the optimum intelligibility
- Great for indoor and outdoor use with environment resistant construction

Just now, mboxler said:
Sounds like we are in agreement. If the Atlas is only flat to 4500hz, and the AL3 tweeter filter has a steep 6000hz high pass, then there would be a hole in the 4500 to 6000hz range.
Yes, it seems to be that problem

k-401 diy (wood horns with the same sizes)
i also have the original k-401 - not better than my wooden self made horns

Clones of La Scala, with Peavey FH-1 bass bins ( Eminence Kappa 15c inside), Atlas sound PD-5VH squawkers and B&C DE10 tweeters.

you know what, i will let my McIntosh amplifier arrive and plug it to the 220 volts sector, and connect the speakers, and then listen to what he has in the body ...
