Whoever said it was a class B amplifier is mistaken or just a slip up in his review. I know of no consumer class B amplifier being sold. Possible in pro gear where distortion is sometimes wanted, guitars. I say trust your ears more than what you read.
McIntosh made a lot of class B amps and you can't say they're bad 😉

If your amp is set for EL34, then you can put KT77 directly it's a replacement of EL34, you just need to change the 4 or 2 and do the Bias setting !
Attention KT77 has nothing to do with KT88 even if the writing is similar to KTxx
look here direct replacement for EL34 = 6CA7, KT77 ...

Hi @Flevoman,
I too have an amp with EL34s, a Cary SLI50. For more dynamics and precision and after trying EL34, EL34B, 6CA7 big bottle and KT77.
My preference is KT77 in 1st and 6CA7 in 2nd. In KT77 I currently use KT77JJ they are very dynamic and with fantastic highs.
You can already try KT77JJ on your Dynaco ST70 first before changing amps

This is a replacement copy of my over played US 1967 pressing
The new record is also a US import
Its a 200 gram Hendrix Family release from 2014
And thank god that they used a quality archival sleeve
Very nice pressing and to my ears pretty faithful to the original if you are looking for a replacement copy
Artist - Jimi Hendrix Experience
Title - Are You Experienced
Album ID - https://www.discogs.com/release/6170798-The-Jimi-Hendrix-Experience-Are-You-Experienced-
Hi,
I'm thinking of buying this disc, but in my country they sell this version, a double LPs SONY Legacy in pressing of 2010, list of tracks of the international version. I believe this is a copy of the English Track Records cover from May 1967, you have a Reprise Records US version cover from August 1967.
It's about this 2xLPs version, but not Music On Vinyl, a close version but only SONY Legacy, I'll find out a little more:

https://fr.wikipedia.org/wiki/Are_You_Experienced#Édition_britannique_et_internationale
Edit : I just found the exact version I can buy, it's a SONY Legacy Europe from 2010 repress 2015.
I like the photos and the inside booklet and the psychedelic colored disc labels.

The gentleman tells me he ran a MC Denon 103 cartridge which has a similar voltage output as the ART9 with this phono pre amp and had no issues doing it.
If the manufacturer/gentleman tells you that it works with an MC, then trust him and test the ART9xi on your set. On the other hand if it does not work it will be necessary to throw the stone at this gentleman.
As Micromara said if it doesn't work that way, then either an MC transformer suitable for ART9xi with a minimum of 100ohms load will have to be added.

Hi
Compared to your previous remarks, even if it is air, unfortunately the volume is paid at a high price, because there is wood / glue / stain, storage, handling, packaging, transport ... and its parts cost very dear. But also what is also certain is that the more air there is, the better the loudspeaker, look at the Heritage range: Jubilee is huge

Hey man, it's me ☺️
When I was 9 years old, around 1971 / 1972 , I had a nice collection, my first records were all 45 rpm EP 7" (45RPM) offered by Antar petrol stations (manufacturer of oil and petrol in France which does not no longer exists) when the car was refueled:
- Ray Charles - Sing the Blues
- The Rolling Stones - Paint in Black
- Louis Armstrong - Frankie and Johnny
- Marc Orgeret - chante Aristide Briant
- Los 3 Paraguavos - Guantanamera
- Tchaikowsky - Casse-noisette
- Aeroplane - September in the Rain
- Les Choeurs de l'armée Rouge - Kalinka
- Sidney Bechet - Black and Blues
- Ten Years After- I'm Coming On
- ...
nice titles for a first collection, right? I still have a few left on my shelves,
and I was proud of my record collection 😉
In the 1970s there was a very big difference between the modern USA with beautiful giant cars and big Harley Davidson motorcycles and our old Europe: an Antar station with a Simca 1000, a Citroën Type H van, a Citroën 2CV van and a small Italian Vespa or Lambretta scooter. And again it is the capital of France Paris - Petit Clamart not the countryside.
Edit : And I listened to the records on my sister's Nogamatic Prelude record player, we are far from McIntosh and Klipsch.

Thank you very much for the tips and help. I apriciate it. 👍🏻
1- my preamp does have tonecontrol and if I want I can add some base. I haven't done it yet but it is possible. Is +1 bass the same as 2 dB 30HZ?
Edit: let me be a bit more precise, is adding more bass the same as increasing the 30hz range?
2-I'm sorry, but I don't you understand what you mean with this.
3-i haven't done much with adjusting the position of the speakers yet. First I want to get used to the sound so i can hear the small differences better.
But I'll give this a try tonight.
4-i will let you know 😉
Thanks for the link. I had read it before. An interesting post indeed. There is also an interesting review online from someone who also had problems with the bass and had solved this by placing the speakers against the wall. (your tip nr3)
https://hometheaterhifi.com/reviews/speaker/floor-standing/klipsch-cornwall-iv-speaker-review/
Hello @Flevoman
Already I must tell you that I am not American, I am French, so be indulgent if I express myself badly and that I write a wrong explanation: if so I think that the Klipsch fans will explain in good American what I trying to tell you.
Now the explanation of point 2: I explained this on page 3 post of June 9, 2021:
To do the test you take a small cotton towel or felt, you roll it tight and you plug one of the 3 vents of CW4.
Felt on mine CW3
You're going to get something that looks like this red curve.simulation made for CW3, but roughly similar to CW4
It is interesting then to raise the curve by 2 or 3 db with the bass button of your preamp, the best is an equalizer centered on 30Hz in our case to compensate for the level between 20Hz and 100Hz approximately and obtain the blue curve: this is what you want. !!! >>>> Of course this remains theoretical and depending on your room and your configuration it may be a little different. And as everything is compromised, the defect is that it raises the distortion a little towards 20 > 100Hz: it's very good for a listening level of 70 to 90db, acceptable for 100 db, less good for 110 db, but the majority home listening is between 70 and 95db, so it's ok
Green curve: original CW4, red curve = cotton cloth or felt, blue curve: cloth + equalizer approximately + 3db at 30Hz
I specify that I did not invent anything, I just applied to Cornwall what Jean-Michel Le Cléac'h (the father of the famous Le Cléac'h horns) had found for the large Onken 360L.
Onken 360L measurements: red 6 vents, green 5 vents, blue 4 vents
Tell me if it's ok for you 😁👍

Mustang,
Good suggestions. Could you please explain what you meant regarding the tubes with felt? I didn't quite understand that. I like your suggestions on the equalizer. Sometimes it's good to add a little something if needed and I love McIntosh too. Gotta get one of their products again some day. I used to have a pair of MC30 monos along with a pair of C8's. Could you tell me the model of your McIntosh in your photo?
Happy listening
Thank man 👍 Mine McIntosh are C504 preamplifier
read there, i described the use of felt in a vent here >>>

Hi @Flevoman
You can follow some tips here to get more bass on your CW4
1 - For me the first advice you can add 2 or 3 db around 30Hz with an equalizer (ideal McIntosh, Accuphase ... preamplifier or new DSP digital)
2 - Second, if you want a slightly lower Hz setting for your bass-reflex: temporarily plug one of the 3 tubes with felt
3 - Try to bring your CW4s even closer to the wall almost glued to it, you will still gain a little bass
4 - Make 1, 2 and 3 and you'll have a ton of bass just the way you like it
Good tests and good listening

Hi @Flevoman ,
Thank you for this comparison, it is very informative.
You have seen what many CWIV users say: lacks a bit of bass and very good mids.-

Hi everbody,
Miami F1 Grand Prix
My favorite French driver is last on the grid due to an accident during practice.
But he's a great Esteban Ocon driver, he's going to try to come back and make a top 10 to get points in the world championship!!!
Pierre Gasly is great driver too !
Good Grand Prix 😁

It's weird, because if you read the manual it says: "40 dB gain suitable for all MM cartridges when used in conjunction with a line preamp with at least 10 dB gain."
and then the specifications of 47Kohms and 40db correspond well to an MM input.
What is destabilizing is that the gentleman tells you that the input is ok with an MC, if it is the manufacturer he must know what he is saying is correct.
You can't do a test with an old MC cartridge lying around in a drawer (run a request on this forum for a loan) just to find out if the sound is ok with the Mapletree Phono 3E before buying a nice and expensive ART9 .

Hi @mopardave
To find out if Mapple Three is compatible with MC AT ART9Xi (great great MC 😍), tell us what your phono preamp model is and give us the specifications of the MC input.
If Maple Three is not compatible with MC, you can try the MM from Audiotechnica they are splendid with a great sound VM740ML or VM760SLC 😉

Hi,
Here in Europe at a lot more increase than at home again. I bought my Cornwall III new and sealed boxes in July 2016 in Germany for €3020 per pair delivered to my door in France (a 1200kms / 750 Miles trip) on a pallet. Today Cornwall IV cost 8000€ in Germany and 8790€ here in France, that's about 270% or 290% increase, it's crazy!

I am stating it as fact, not implying it. I see once again you are right.
To the OP. Jimbo stated the improvements very well and I agree 100% with his comment. Ultimately you need to listen to both, before buying either. Big boomy box sound was a big enough problem for me that I quit looking for old CW's to fix up because I did not like the box effect. Which by the way was still there with the CW3. The CW4 has new mids and HF and has bracing from the front to back in two places which eliminates that tone killing resonance effect you get with big pieces of wood. When I want to hear the resonance of deeper bass stringed instruments for instance I want only that and not the added interference from board vibration. There will always be some I know but it needs to be muted. For my taste the CW4 is more lifelike and noticeably more so than it's forerunners.
Hi @Dave A and all,
CWIII also has the same wooden braces as CWIV. On the other hand CWIV has a plywood board at the top of the enclosure this is perhaps the difference with CWIII which does not have the plywood board.

Hello !
Interesting reading, CWIV new Tractrix ports, mid horn is most definitely superior in quality (Tractrix, mumps, top surface....) to CWIII small horn, but some things were good in CWIII too:

Hello !
It's been a long time since I put on an original record that I bought at the time in 1981. It's an LP of German artists for our friend @MicroMara, because he likes it when I put on records from him in Germany 😎

Hi,
Among the avenues to explore: Without music, try gently pushing the cone (not by the dust cap) several times: if it scratches, the coil has burned and the varnish is rubbing the air gap, or the spool holder is deformed and rubbing. If so, the coil or the cone/coil/dust cap assembly will have to be changed.
You can use the Chat here or ask your questions, they will guide you to repair your speaker:

Or Klipsch support !
If you need to change, use either 2 repair kits or 2 identical speakers to have the same sound on each speaker.

Hi @homatose
If Part-Express glue is not available, you can help out with wood glue. Use a glue that is not too liquid and without too much excess in quantity, in any case to prevent the glue from flowing towards the coil of the Loudspeaker. The white glue will become transparent and almost invisible after drying.
good repair 😎

Example and Explications the MC2255 :
http://www.hifi-classic.net/review/mcintosh-mc2255-284.html
The output stages of the MC 2255 operate in class-B, but a unique biasing system completely eliminates the crossover distortion usually associated with class-B operation. This being the most efficient mode of linear amplifier operation, the total power consumption of the MC 2255 from the 120-volt a.c. line is only 0.7 ampere at idle (or normal playing volume) and 12 amperes at full output. The input and driver stages form a complete class-AB low-power amplifier which drives the front-panel headphone jack as well as the power stages. Switches connect the input sections for mono operation. In the mono/parallel mode the right-channel input drives both output sections in phase, and for the mono bridge mode the other input section is used as a phase inverter so that the outputs can be driven 180 degrees out of phase.
