if only you actually understood anything you wrote

Dunning-Kruger is affecting you Mr Wayne. By all means, do your reach around word salad with zero data thing and point out my technical errors, given you audiophile knowledge.

Please post up a square wave response of your favorte class D amp ..

That is your burden Mr Wayne. You have no clue what it represents anyway, but amuse us. By the way, which LP music do you own that produce square waves?

 

[a.wayne]

BTW Before your usual tap dance and deflection name one of your favorite Class D amps , one you actually use ..

Ahhh, she sings ....

what about the same break down on class D specs , must be a reason for that thin metalic, non natural sound ,

Go ahead educate us ...

We're not seeing any square waves or errors in my explanation above Mr Wayne. Having trouble reaching around today?
We actually have (again), actual equipment model numbers.

Running out of google knowledge their maestro ,

1.still waiting for your personal recommendation on a class D amp ..
2. Similar breakdown on class D specs , anything funny about those squarewaves ..

3. Compare the MC275 squarewave output to your favorite class D , notice anything ..? Whats the importance..?

help out nuh ...!

AJ, The Specs either means something or they don't, its not a buffet , maybe David just prefers the sound of his toob Mac , like you and Class D bass ..!

The irony huh ....

Campion college followed by the USF EE program and the last 20+ yrs work in engineering, provided that knowledge Mr Wayne. Other than your posterior, where do you get yours? :lol:

1.still waiting for your personal recommendation on a class D amp ..

Sure, right after you tell us your favorite square wave vinyl LPs. Albums names, vintage etc.

3. Compare the MC275 squarewave output to your favorite class D , notice anything ..? Whats the importance..?

This is your audiophile pet peeve Mr Wayne. As such, reach around and tell us Mr Wayne, expose your actual technical knowledge. Be sure to cite exactly what is audible about the visual shape of square waves, citing all the relevant AES controlled listening test papers. Oh wait, you're not an AES member are you? Hmmm. I wonder where the source of your audiophile knowledge originates?

Please note I provided David very specific data about his amp/speakers, not just hand waving word salad innuendo.

This has been a fun thread to read.

I also have the MC 275 along with some other McIntosh amps like the MC 602 (a beast!) and the MC 2301. I have owned a bunch of other amps, mostly solid state. The MC 275 has a sound of its own. It is colored, but I think in a good way! If you like it, stick with it as you won’t find an amp, solid state or tube, that sounds just like it.

To your original question, I do not know what objective characteristics make the MC 275 sound like it does subjectively. My guess is the usual
measurements don’t tell the story.

good to know i ll keep it in mind ! thanks for sharing your more advanced experience

to AJ soundfield:

this goes well with what W9TR was saying: the 275 is kind of unique in the "special effects" it produces even among other mc....
I thought I red everything about this amp at the time of purchased, certainly came across this Jon Atkinson article and could not understand the graph at the time: just got the conclusion, which meant : GO FOR IT! to me.....

I will come back to this reading in full depth... I do not touch all the knobs every second while listening (as some others do), as I finally got back to listneing to the music and not the units, but I still enjoy to understand new thing about my hobby: for this thank you so much ! especially if there was football on TV !

as for the 4430 crossover i just redone the same as JBL without the switch for biamping, and placed two input one for the tube amp and one for the SS, in order not to have to unplugged speakers every time I change amp... just have to be carefull not to have them on together....
Found on the very very good LANSING heritage forum, all the values (thanks to the regretted Zilch RIP) everyone have access to the R value of the inductances etc...it was fun to do and I got more "hifi" type of response with the jantzen components; I even was able to find the the special wirewound rheostat at the exact value specified by JBL for almost nothing (https://www.amazon.fr/gp/product/B01482HK6W/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) .... now with the new pots and some placement experiment for the speakers, REW has nothing to say on my FRC after 400 Hz....
that s just it

Who won ?

 

[jahjahlove]

Big uppercut there Mike ...

really ? in primary school may be....

 

[jahjahlove]

Please note I provided David very specific data about his amp/speakers, not just hand waving word salad innuendo.

you are the only one who did yes, or tried...; and i thank you for this....

Please guys i had no intention of starting a conflict of person here, let s stay gents....

Thing is some people tend to think that because science cannot explain everything nowadays (in general, not Hifi), science is rubish...
in France we call this "throughing the baby away with the water of the bath"....

that is forgetting how science is working, and how humble is the scientist facing the world of complexity.... this certainly doesn't mean science is useless of course, and certainly even less a reason to stop thinking

Hi David,

Yes, I can see from JAs measurements why this would be a popular amp. It will impart some tube "warmth", but not have the excessively flabby bass, nor extreme EQ (reacting to speaker impedance) "effects" etc of a very high output impedance, say, some typical SET. Warm, but still dynamic and tonally balanced. Different strokes for different folks...as always!

I do not touch all the knobs every second while listening (as some others do), as I finally got back to listneing to the music and not the units, but I still enjoy to understand new thing about my hobby: for this thank you so much ! especially if there was football on TV !

that s just it

Ok, so made bi-ampable with switch removed. Ironically, the impedance of the 4430 is quite tube amp friendly, nominally highish and constant. Sounds like you just need a more powerful version of the 275!
Zilch and I were kindred spirits, we corresponded on forums and agreed on just about everything, since he actually knew what he was talking about, unlike my friend Mr Wayne. (btw, you probably don't realize, Mr Wayne and I know each other, our jabs are all in good fun. He really enjoys totally embarrassing himself).
I guess my only question is, what does the 275 lack, just more volume? The Crown should have plenty power to drive the bass section to very high levels, so I'm guessing this is where you are searching?

Who won ?

Both my teams, thankfully, including the above mentioned USF. Different type of "football" from where you and Jahlove are from of course. Btw, is this reggae bass we are after?

cheers,

AJ

CDRe: Please explain to me

I guess my only question is, what does the 275 lack, just more volume? The Crown should have plenty power to drive the bass section to very high levels, so I'm guessing this is where you are searching? AJ

Well not really more power, I had two 275 for a time, placed in mono , but from what i can recall, and allthough some might disagree here, i thought i was loosing in dynamics as compared to stereo mode... correct me if I am wrong.... one of them had a bad transfo and i sold it fast (oups)....It was coming from audioclassics in NY !! I live in a flat and have cool neighbours (or shy, or cawords...) so playing at 130 dB is not what I am looking for... I was happy to hear joe here, stating first thing after purchasing he 4367 that the best sessions were with the his MC75 when he has everything at hand costing 5 times the MC75 units...

I have started a reasoning about analog versus digital RECORDINGS. I was trying to avoid the usual boring fights about the two, and
I came up with the idea of playing the music as it was recorded: so analog recordings being played with a purely analog rig (turntable) and digital recordings being played with a digital set up (streamer, DAC, DSP),...respecting the work of sound engineers from scratch. Not mentioning the oversampled, so called Hires sold on the net, being in fact normal 44.1 16 bit just oversampled as SACD ! what a joke!
I value DSP for room correction and was sorry to have to go through two conversions with the Crown, when I struggled to find the miniDSP 2*8 that is inserted between the source and the DAC... I even bought a second DAC to do biamping with only one conversion, the latter beign made by the Bryston BDA2 for the mids and highs and bought the very interesting SMSL 8 (cheap and 90 % of the quality of the Bryston, for a 10th of the price beleive it or not); Unfortunatly for me active crossover requires to learn a new soft because implementing in it what JBL did in passive led to bad results...work children and all prevented me to go forward recently with active crossover soft... audio architect is quite nice thought, and easier to use as I first thought....used 10 % of it obviously...

the other reasons are:
- my room for not being squared, is still hawfull with wooden floor, concrete and large windows.... had so many difficulties to place my sub that was completly useless in some places....(i do not have a dedicated room) (but I have an infite WAF! luckily)
- As I work partly at home I have sometimes 3/4 of an hour of listening before leaving for an appointment and was sick to have to leave the Mc just when the tubes got warm and nice....
- lastlty JBL recommands 300 W for the 4430 and pros are advising to double the figure to face peaks....so I was eager to get that power... some here will say just buy two MC2301... yeah... don't have the money.... I guess, for some, that makes me a shit...not worth reading.

Re: CDRe: Please explain to me

Well not really more power

I have sometimes 3/4 of an hour of listening before leaving for an appointment and was sick to have to leave the Mc just when the tubes got warm and nice....

- lastlty JBL recommands 300 W for the 4430 and pros are advising to double the figure to face peaks

Well....
Sounds to me like you need a powerful SS amp that has a nice dose of even order distortion and maybe a transformer for some saturation. Instant tube warmth with little warm up time. Hmmm. Not really my domain so I will have to defer. I know there are probably "amps" like that out there.

cheers, AJ
