Can somebody give me their expert opinion on the End Millenium amp by LC Audio of Denmark? They sell a kit and make great claims. The circuit diagram is also detailed.
This design has a slew rate of about 250V/us so they say.

No global feedback, that's different from 99% of the amps
out there. Some people think that's a good thing. I think
it needs to be critically listened to.
Personally I'm skeptical, but I'd have to listen to be sure.

And I would be interested in opinions on the Sidewinder pre-amp offered by LC Audio as well. Anyone have an opinion they would like to share?
Thanks in advance.

LC audio is an interesting company. They are very quick to adopt new technologies such as schottky rectifiers (now that you can actually get HV units) etc. They have also been good at bringing product to the market in a timely manner -- such as their clocks for CD/DVD players. I have been in contact with them once by email regarding one of their technical claims and the response was quick and polite. They are good at inventing new pseudo technical marketing terms such as ULC, non-paralell capacitors. They will also tell you that surface mount components rule because they are shorter (could well be true all other thing being equal).
The Milennium units have been well received in the Scandinavian market. Reviews range from good to "better than Levinson" -- the latter mostly from the Danish press, and I am not all that impressed with the integrity of audio magazines in general.
My PERSONAL opinion is that these units are a little too complicated. Several gain stages etc, but this is what provides the frequency response I suppose. BTW, I think you get the circuit board ready made and soldered which is good considering there are lots of surfac mount components on there.
I decided not to go for these units after extensive review. Then again, if you search the web you will find reputable people who claim the products are great.
The preamp is an op-amp unit. Opamps are veru good these days -- that's all I will say about that.
I think you can still download schematics from the http://www.lcaudio.dk or .com site.
I would say it is quite costly when you add up all the parts, but probably a capable performer. I have heard them, but not in an environment that I am familiar with.

The EL amp from LC looks very interesting.The voltage gain stages are the same as a Hafler DH200/500 with more local feedback.Of course the only difference between the Hafler voltage amp and the Leach is the current gain stage between the diff inputs and the second voltage amp.Rotel also uses the same topology.So does ATI.So did the Adcom GFA585.GAS, SAE,the list is long.It would be child's play to buy an old SAE MK XXX for less than $100 and soup it up like this.
Andrea Ciuffoli gives a positive review of the End Millennium if anyone cares. The signal path is very short, the board comes almost completely assembled and it probably takes a few hours to put everything together and move on to the best part that is listening to music.
Lars Clausen (LC) has been very nice to me in the past and I thought about building this amp for a long time. I ended up going with a cheaper alternative. He goes for such an unusual designs probably because he firmly believes in the sonic advantages associated with them. That same philosophy seems to apply to all Lars designs and I like that kind of attitude very much. I think the amp itself is a pretty good deal considering the quality of the components. It used to be dirt cheap about a year ago before the prices got jacked-up about 40%. However, the whole package costs too much in my opinion. An amp I am thinking about building is the Zapsolute 40W class A 0 feedback. It would be nice to read actual comments about the sound.

I built an amp based on the End Millennium kits and finished it in January. I chose to order only the circuit boards from them and did the power supply, case, heatsinks etc for myself...
I have one transformer with 24V windings, four bridges, 10000uF capacitors for every output stage power line and 4700uF capacitors for every pre/voltage amp stage power line. The signal comes directly from modified Marantz CD67mkII cd player to 10K alps volume pot and then to the input of amp modules. I use Dynaudio Audience BM-5 studio monitors for loudspeakers.
The sound of the amp is very good in my opinion. At first listening it felt to be very strange (my previous amp was NAD C320). After some days of listening I got to like it more and more. The biggest plus in my mind is that the amp doesn't cause listening fatique. The NAD amp was awful compared to it in that sense. One thing that I also discovered is an effect that I don't find good words to describe, but what to me is something of a better dynamics. The amp has a great capability of producing voices and instruments individually. Marie Boine Persens - Gula Gula record for example sounds absoulutely great. There are many sogs where with with quiet and them loud passages and one can really feel the emotions involved. Very rare amps have pulled this off with similar quality. I also had a Marantz PM-17 for repair about 2 months ago. I then compared them. The Marantz had a pretty good sound with low listening levels and simple music (only couple of instruments at the time) but had a lot of trouble with complicated passages). For example The Corrs "forgiven not forgotten" gets pretty complicated when the whole band kicks in. Marantz got very fuzzy and totally lost the control over the music. The End Millennium on the other hand feels very comfortable with such music. The only thing that was better with Marantz was the control of the lowest bass notes.
One of my good friend found The End Millennium to be almost 1:1 with Accuphase E-407. He has experience with Accuphase I don't, so I can't comment on that.
The project has cost me about 450 USD and I consider the amp to be of exeptional value for the price..

The End Millennium vs Accuphase
Hello.
Ergo
I'm interested to know your comments on sound quality of The End Millennium amplifier vs. Accuphase E 407 amplifier.
Which is the difference between the amplifiers?

Looking for amplifier modules
Not sure if this is the right place to post a query, on a thread that's been "asleep" for almost 3 years but here goes. I'm trying to buy one or two End Millenium amplifier modules. While they're still displayed on the LCAudio web-site, I understand they are in fact not available at all from this source (misleading advertising perhaps?). Anyway if anyone has a fully functioning module or two, I'd like to hear from you.
Fingers, toes, eyes.... crossed.

Hello,
just like Rob A,after a few good years,only 5 !, I'm trying to find the pcb module with throhole component for End Millenium amplifier.If anyone can help me ,please email me.
My special thanks.

This URL is death. To get informations of this amp, go to
L C Audio Technology/The End Millennium
Are there a currently available power amp modul in the same kind, i e. without global negative feedback and only local serial feedback ?
Or exist a successor board of this millennium amp (not the class D "ZapPulse 800XE", this isn't a real successor because class D - go to
http://www.lcaudio.com/index.php?page=31 and
http://www.lcaudio.com/index.php?page=200) ??
Thanks for advices.

A very good sounding amp.Use a god size powersuply.have had 4 of them over the years.stil have one dual mono with extra output transistors so i can get 2 times 180w or 4 times 90w aproximatly.Bi amp of speakers is posible to use when you have modules with 2 extra output transistors in adition
Some other guys tell me, this power amp module operates without any feedback.
But this is wrong, because a certainly voltage gain factor is to define by at least one serial feedback loop; so the right claim is, no global negative (parallel) feedback loop.
That means for me, no feedback loop from output to inverted or non inverted input and from there to GND.
According the schematic on page 8 under
https://web.archive.org/web/20011110044633/http://www.lcaudio.com/millmateng.PDF
resp. the PDF attachment I note at whole four resistors resp two local feedback loops, which determine the voltage gain factor of at whole ~ 30 times:
1) input differential amp (LTP): R18 : R10, means 4K : 2K = 2 times
2) VAS (voltage amplifier stage): R4 : (R17+R18) means 30K : 2K = 15 times
Is this correct or am I overlooking fundamental aspects for the correct calculation rules ?
Thank you very much for comments.
I ask this, because a friend of me want to create an amp project with a selector for different feedback loops:
1) serial feedback as realized on this amp
2) parallel (global) feedback -
a. as mostly used in a non inverted mode
b. in an inverted mode with only 100-400 ohms input resistance
3) mixed feedback
