Class D
Is class D to keep small guys out ? Class G does very well . Many are using it who looked at D . D has back EMF problems . I like tubes myself .

I have been on the Naim clone site . That's my advice . Bend that amp to what you want . Reliable also .
JLH also is very good and easy . There is a back lash against class D . It is like Vinyl against CD . Have been using Fostex recently in active set up . 300 W bass and 10 watts top . It works .

I had the JLH 80Watt Mos-Fet amp based on the Hitachi 2SK/2SJ devices.
It fades into the distant horizon when compared with the Pass Alephs.
OK the cost of building a Pass is considerably more and the components are difficult to obtain, then you have to match them. But I wouldn't bother with another JLH design.
The Pass Alephs are SE Class A, I still find them far superior to Push-Pull Class A. The power is limited by how much heat you can get rid of but the benefits IMO are HUGE.

FWIW, I was in Nashville yesterday to listen to some small Meyer Sound line array boxes. We already own a good bit of Meyer, and want to buy more.
Listened to the Mina and the M'elodie arrays. The Mina is a very small box at about 40 pounds each. 2x6.5" drivers + horn. Nice sounding, but very forward in a P.A. sort of way. They can get very, very loud in an array of 5 or 6 per side. With six little (dual 12") subwoofers, it will knock you over.
Then we heard the M'elodie. A slightly bigger box, but a huge difference in sound. Very smooth, very rich. Like a Hi-Fi PA. You just wanted to sit and listen to track after track on these. Or as my buddy who was with me said "I wanted to kiss them!" 😀 Plenty loud, but no sense of strain, roughness or fatigue.
Not the best sounding speakers I've ever heard, but the M'elodie is may be the best sounding line array I've heard, and in the top 5 for P.A.

I'm told Meyer are good . My friend has Turbo sound which is what he can afford . He says like you . He plays his rig low as hi fi .
Best sounding "loudsprecher" system ever!
Love it! I bet you'll get a lot of mileage out of those!
Hey, the tires ought to make for great edge diffraction control. Cool idea.
There are two pairs I would say are the best I have heard thus far, and of the two it's a tough choice but it comes down to personal preference.
The two pairs in question were a set of Magnepans, of which the model I cannot remember but retailed for around $6000. The other set is the IMF TLS 50 II's.
Where I listened to them they were on two entirely different set-ups and rooms so it's difficult to compare, but the sound of the two is somewhat similar. I would say that between them I prefer the IMF TLS 50's. The room the IMF's are in is smaller so the size comparison is more comparable in that sense.
The sound out of the Magnepans was very open and spacious, imaging was precise but I found it to be lacking depth. That is where I prefer the IMF's. The enclosure design allows the bass to be very smooth and responsive (with a high damping factor amplifier), whereas I found the Magnepans although similarly responsive, not to have the same kind of smoothness to the bass. You would have had to add a subwoofer. To me, adding more components to the mix is a no-no. I like simplicity. Plus, the look of the IMF's is vintage and you can't beat that.
So short answer, the best set I have heard thus far would be the IMF TLS 50 II's. And of course, when I get the chance, the IMF TLS 80 II's!

IMF . I played with some and never got to know them very well . I do get asked about these things . Any idea which amp suits them best if money allowed ? I remembered a Luxman tube amp with some . Unfortunately IMF clashed with trends in UK at the time so no one I speak to knows a thing about them .
They are beautiful speakers. The bass is something else - something to be experienced, for sure.
The best kind of amp for these would be one with a decent amount of power and a good damping factor. A tube amp with decent power (say, 25-30watts or more) would be preferable. The current amp I am using right now is a Pioneer VSX-37TX Elite, which is a solid state AV receiver from '02. It doesn't have enough power to run them the way I'd like (lack of bass) but the bass is very tight due to its higher damping factor. When my Sony STR-V5 comes back (also solid state) I am going to be using that primarily, and I'll comment on that. It has a low damping factor (40) so I'm not sure how well it will work, but it should give me a good idea of what kind of an amp these speakers will need to sound their best.
Basically these transmission lines have a high focus on the bass - that's where these shine. The IMF's in particular though, if you get the models with the Audax tweets most definitely shine with the high range as well. The midrange is a little lacking but luckily for me I picked up the IMF's with upgraded crossovers and that has helped it quite a bit. Quite a flat response overall I would say.
I should also mention the IMF TLS are rather inefficient - around 83dB at 1metre with 2.83v. However with a decently powered amp they are easily drivable.

IMF
I think our houses in the UK a bit small for them . I was told that businesses was so tough they invented a swimming pool cleaner . No idea if that's true ? Perhaps big Yamaha would suit ? No idea . Thanks for that . I tried them with Naim and Quad if memory serves me correctly . I think the UK didn't take to them .

You are probably right. The IMF's are rather large speakers, and from what I remember reading about IMF as a brand they did better in US markets. They probably cost more due to importing, but I would have to agree that those who sold the IMF's and knew what these were sold at least a few pairs!
Unfortunately the smaller room I have mine in definitely compromise the sound - it's quite noticeable, but I'm saving these for the next place I move into to get them into a bigger room. I'd imagine that a room say, 20x20 would be ideal with the speakers placed roughly 8-10 feet apart and sitting about 7-8 feet back. Ceiling would have to be at least 10 feet high as well I would think. You can use these in a smaller setting, but the size would make them less attractive in the smaller European homes.

Much more to this part of the story. Bud Fried and the original transmission line developers back in England (John Hayes John Wright and David Brown) got locked in a protracted legal battle due to Fried's (who was the U.S. Distributor) insistence on building "inferior" versions of the Transmission Line series and slapping IMF badges on them. Most of the IMF's sold in Canada and the U.S. were of U.S. manufacturing origin. Good yes..but not near the level of performance of the actual Made in Britain versions...I've had both.😀
Well, since we are now commenting on speakers that we have NEVER heard, then I have never heard the big Wilsons, but I was told that they sound really good.
I have also never heard the JBL K2's, but I was told that they sound really good.
I have also never heard the Gedlee Summas, but I was told that they sound really good.
The list is actually pretty long.
Dutchie ur special .......
T&S ....? Redbull has their vig fully paid up , no worries at the moment... 🙂
A double pair of Dayton Wright XG 10 - amazing bass and dynamics for an electrostatic driven by a Dunlap Klark 1000. A set of Wilson Wamms i heard in Macau driven by Audio Rrsearch power amps. Focal Grand Utopias driven by YBA passions in Montreal.
