I am NOT going to buy a new set of KR 2A3's just to compare to my "vintage" ones, especially considering the price has gone up to $800 a pair!
However, a NOS pair of Sylvania "spring top" 2A3 tubes is on the way to me. So I will have some things ...

So I've taken a look at it. You can mount 2 different motors, one to control azimut and other for height. Every single motor costs 595 euros, and having both combined goes to 920 euros. Looks like the control system (PC compatible by RS232 link) is i...

I have noticed the same kind of control and "density" of sound from KR audio amps, which are zero feedback. Have you tried this brand of amp? The one thing that I can tell conclusively about the two different amps is that neither one suff...

Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...
|
|
Brad, I heard a KR years ago, only remember it was not the typical "no-feedback sound", which I think of as clear but flaccid and no push. I agree that "feedback" can eventually ruin bass, and more, as I mentioned earlier in connectio...

Oh my god!I just saw a report about the last Highend and realized Cessaro was already present, that was the room I entered because of my interest in the KR monster triodes, but ran out after two seconds. Cold, sterile, and not 100% fre...

What I find interesting though, Romy, is that many of the SET measurements show gross distortion even when putting out very low power, which suggests that they are saturated from the high static DC current running through them as they must for a Clas...

Having listened for a while with the tubes, I have come to some conclusions. The three tubes I have seriously listened to are: Kron, Sophia, and Emission Labs. All the tubes are much better than any other modern 2A3 tubes I have tried. I felt my in...

[quote user="drdna"] If you were using, for example, the Kron KR 2A3, you would not be commenting on the sluggish liquid sounds, and it would be very much more competitive with the Melquiades I am sure of it. Adrian[/quote]I doubt swapping...

[quote user="Romy the Cat"]I was listing it and I did not really like what I heard. It was all together juts some kind of “Ordinary Sound”. I recognize that I say “I do not like sound” but I can’t say anything more spastic. All of the sound that I ge...

Hi Jacky! Nice that you show up in our rednex discussion ;) I remember too. Thats a nice shot with E&S. Hope you got some response out of your show. Keep us updated about future changes. Would be very interesting whats going on behind the curtain...

Dealing more with Sun Audio SV-2A3 kit it amassed me how bad the kit was. The guys made very cheap, in fact I hardly believe that this company has anything to do with Japan – it looks more like K-Mart level of amplifier. I heard a number of very posi...

I assembled SUN 2A3 amp for my friend and found it to be quality kit and very easy assemble. Kit was old .I think late 90's so maybe quality deteriorated since then. I have variety of 300b Czech tubes and (Eml 300b , KR 300BLX 842VHD ) bought t...

[quote user="morricab"] You are also right that to get everything you want from an output transformer requires a VERY expensive construction and top materials. However; even an expensive transformer is no guarantee of success. [/quote]
Sorry t...

Yes primarily i viseted Thomas to compare tonearms, he has a couple of Schroeders, the new graham Phantom ( mark III ) a vintage Ortofon amongst others. and he has a fine collection of cartridges, as I mentioned he is a very nice guy, The real surpri...

[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...

I just visited the Highend in Munich and had the chance to listen to two of those monster SETs. Cessaro showed up with monstrous 833 amps and my thought was that there is something wrong with the music. I know it is common in this forum to describe w...

[quote user="Romy the Cat"]Can you post or explain the topology of your 6SN7-2A3?[/quote]The amplifiers I use started from a kit I bought, the Moondog, so here you can see the basic topology. It is very simple. The first stage here can be eliminated,...

Does it also apply to the new generation of 300B's 300 BXL from AVVT , KR or EML ? These are different designs and supposed to address the issues with 300b signature .What tube (besides 6c33c) is a good starting point for an amp in your opinio...

Merlin here is the Stereophile measurements on the Lamm ML2.1http://stereophile.com/tubepoweramps/1004lamm/index4.htmlAs you can see the rise in distortion vs. frequency shows only a small rise in distortion even down to 10Hz. This is an indica...
