Oh, did-you run away from "simple is beautifull", or it is just playing around with better CSS, filtered rails for more PSRR etc... ?
or, if you prefer my question more direct: "More poles in the loop?"^
Hose4, reading your listening report, it seems you know what and how to listen ;-)

Not quite so true dear Christophe, First One v1.3 is max what you can get from low device count, step forward is not so simple any more. The gap becomes even greater if the goal is uncompromised sound quality which is exactly what I am aiming for.
Are there such people?...I can't put the words Enjoy and SMD in one sentence...lol.
Different sizes of the new version, that nice news! (what about the sizes XS and XL?..lol)
In the meanwhile I am drilling what looks like a Million holes in Aluminium sheets to construct a V1.2..
R.
He he, you don't want to answer my question ?
I was not referring to the number of devices... It is not paralleling them (specially power devices ;-) witch can add prejudice.
Neither cap multipliers for input or VAS stages and even servos. I used Cascodes to can afford high voltages, and this don't add a pole, on the contrary. My question was about added drivers, superpairs and so in the loop witch can be more "acrobatic"...
Distortion numbers VS stability and slew rate...
40 semiconductors seems enormous, to me. But i suppose you count diodes, LEDs etc in the list ?
Just interested to figure out the level of "complexity" after what we blur the signal instead of improving the things.
But, if you don't want to say anything about your new amp, it is the vendor's Bazaar, after all 🙂

Few posts back I said it all about topology and since they've put me here long time ago I will say no more, I would just say, adaptation to situation. 😀
But who cares, I have continuity from starting version and if it ain't for the better I wouldn't change anything. I can assure you the latest version is a major step forward which reveals every little detail from recorded material, otherwise it would have been meaningless, all this effort and time developing new version.
OK, with looking to our solid state side of the forum and theirs major threads I can only say, it's different. Pleased? 🙂
Can you tell us a little bit about the power supply voltage requirements for the different versions? And maybe the retail price of those units? Thanks
Never short circuit a transformer coil. Forget about CT, you have no need for it, unless the level is too important. In this case, you can use CT and dot, and let the- of your output transformer unconnected. Just imagine it is 110V+110V AC coils !
So + of the RCA is your dot.
Ground of the RCA: or CT or - of the coils and you bring the ground to this point.
Sorry, but it is basic.
You can imagine.
As much as somebody that starved to whom some offers an olive ;-)
But, hey, man, you have my PM, and here my public "non disclosure agreement" ;-)

haha, wink noticed.
It is always hard to quantify playback of music. Listening to music as a whole is final destination. The most beautiful part of listening is when you just enjoy and don't have the need to dissect. I call this sound FLAT, nothing sticks out. System has no or very small character of its own.
When trying to assess the sound of amplifier (or any other component), in order to compare, you have to "breakdown" the music to sound, listening to different parts of spectrum and in the end, of course, as whole.
About 15 years ago during online forum session, we had a really heated discussion what is good and what is bad in an amplifier, system, describing the best way we could. Each one of us had different was of description.
In the end we decided to meet and listen together. We found that we talked about the same thing but using other words to describe it.
For instance: the reviewer would say, sound was big and expansive. I honestly do not know how does this sound. I try to imagine. Yet if somebody would tell: On the ampA the instruments/vocals sound smaller than on ampB (both adjusted to same loudness). Smaller sound means to me that system has better focus and as a result you can play the ampA louder than ampB. If at the same time you can better hear acoustics of the room it means that amplifier has better resolution. Probably less fatigue.
There are more parameters of course. It is not a perfect system, but it works for me and I can better give opinion about a product.
I make my own cables. They are simple to make and to me they don't have a sound. LC came for a visit with VSSA at the time he insisted to used his QED interconnect. After some time I switched to mine. The presentation changed, we could all hear it. I asked what sounded better and got some confusing answers, mostly that QED is better because it costs 300 EUR. After I explained what I heard on the dirt cheap cable, we listened again. LC uses similar signal cable now. But this is a philosophy and it would need much more space to explain.
I hope I explained a bit.
Maybe it's just me, but i think this time you should put a bit more effort into marketing this to us. The FO 1.2 was supposed to be the best amp on planet Earth and the 1.3 was substantially better 🙂
Sadly, to my ears the 1.3 did not advance any of the areas where the 1.2 was lacking.
So, maybe it is time to disclose what do you feel are the weak spots of the current FO and in what manner does the 1.4 improve upon those. You've got to give us something...
With my respect to LC, I think its about tuning the new version maybe, or may be to sell more.
Too bad, I do like SMD 😱
Sure no problem! Just send me a sample pair and I will gladly review it 😉
Ciao!

I think it is just you, I have yet to build to build my 1.2, and "Yes" I have high expectations reading the posts in this thread, but I don't have the idea this is "the best amp on planet Earth" (I do hope it is). The "upgrade" to V1.3 is something to look forward to. The term "substantially better" is in the end a personal thing. I don't think LC has made false claims/marketing.
I am still looking forward to my 1.2 build and the version after that..
R.
Look forward to hearing what the cost will be.

I just assemble FO and i am measuring output bias current. When it should be 280mA? 1 sec after switching on, 10sec, 1 minute or 10 minutes? Because my amp is showin around 254mA right after the start (about 1 sec), then after 10 sec is on 270mA, then it goes to 295mA in about 15 min... I am confused :/
Don't be. It is not so critical. It seems your numbers are OK. Listen to music for at least half an hour as it, in order to let your amp stabilize temps, tune your bias as requested, and... forget-it 🙂
Or forget-it as it is now if it is not to hot. A little more bias can't be bad to stay in class A as much as possible.
I am sure L.C. will say the same.

Sadly to your ears yes, but hey others did notice the advance, as all reported for the better.
40 transistors? Best amp on planet Earth? Simply cannot find the claims where I stated that. 😀
First One v1.4 made its way because you wanted it, all remarks about capacitors in signal path, etc., now resolved. Wait and see, the judgement will be on you all. 🙂

Yes, very sad. Although I wasn't expecting a verdict on my hearing, but rather a reassurance that 1.4 will finally have bass quality to match the rest of its virtues. Vague statements about the improved sound and the semiconductor count will not persuade me to upgrade.
