Hello gents
RCA and XLR are driven by same output, same secondary winding.
The difference in sound comes down on primarily what the dac is driving, and ground.
Also the winding has a slight edge to performance when driving unbalanced loads. But this is minimal.

Hello to all
We had already (unofficially ) announced about the launch of the Ianus Series phono stage, the Kirke..
Since first units are being shipped, we had a photo-shoot yesterday. Hope to have the official page in a few up and running,
Some casual phone-pics , from the session.

Hi
6j52: A very nice tube, especially when we use it on TriodeFet.
-------A word of advice for these, a lot of these were made with Pin 1 unconnected (only pin3 used for cathode, not 1+3 ) so proceed with caution ----- Good thing, it is easy to spot which ones have pin1 NC

Hi David
The tube compliment choice (single, dual or combo) will be the first, when choosing how to better suit/alter the amp to the system (if you have tubes to play around that is).
The bias system then comes into play.
You could be right, as with everything , it is a slippery slope. Once...
Hello David
You should of played with bias and /or tube rolling. The TriodeFet bias system is not like the normal bias systems in other equipment, where you have a linear scale which there is a sweetspot and you can move around it, but more like a 3d "bias"
space , that is crated by the many...
Hi
Pondera is the first of the Legacy Series.
We decided to name this series of designs that are making comeback, as Legacy.
Performance wise it belongs to Sig series level.

Hello to all
Here is some info and casual pics on our brand new design, the Pondera (ok, not so new:)
The Pondera pre-amplifier was one of our early designs, on the very beginning of the company. The first Pondera was designed in 2011 and was demoed at the 2011 Munich show. In my ears this was...
Hello
1.Yes the gain will change accordingly, depending on the tubes used. The final transfer curve of the amp is a combination of the transfer curves of the two tubes.
Example, using dual D3A would not present same gain as a combo of E282F and D3A(in reality the gain will be much closer to...
Correct, well, 99% correct.
As far as i know two factories made these, Phillips and Siemens.Valvo seem to be made by the Phillips ,judging from codes and internals but could also be from Siemens(example i have found Mullard made by both factories.)
As far as SQ, according to our internal rating...
Hello
We are always busy as heck but steal some time to come here:)
I thought i made a good job on replying on this question with the link above:)
As i mentioned, Essentia as well as the other TriodeFet amps do not stutter on difficult loads, however 40W is 40W , in terms of max spl.(regarding...
Hello guys
Driving capabilities of an amp is one thing (not falling apart in dynamic passages, behavior in non-resistive speakers, impedance drops etc) and max spl is another aspect alltogether.
For max spl, there are a number of calculators, one of which here...
Hi
The Impera comes in three gain versions ,low,med and high(high was the original version,which fitted perfectly low gain amplifiers but a bit hot on solid state amps).
The low gain is suitable for all SS systems as well as the mid version.

Hello
Thanks for tackling the typo,it is 500mm wide not 470mm.
Yes there is a 4-pin HT xlr driven directly from the power stage output, just like Genus.
It is fed directly without any switch no.

I am sorry but based on last response i think you are just trying to be argumentative for the sake of being argumentative. I am not going to run on circles for you sorry
Single stage amp means provides both current and voltage gain in a single stage. If it provided only current gain with unity...
Si
Single stage, is pretty much well defined term and not a term you can bend to liking.
The name we gave to the tech might be cute, don't know about that :)
Cheers
Hello
While we finish up it's website(finally) here is some info:
Protos dim is 500mm W X 490mmD x 170mmH, these are max dimensions, not footers placement
PSU is 190x 300 x 90mmH
Without too much stain, allow 20cm for 90deg curve, but even 15cm is strainless
Total weight is 65kg
Volume...
Thank you for the visit,it was a real pleasure to have you visiting here, and appreciative of the fine words and writing.
Very happy to welcome you in the AC family
BW ,Stavros
It depends how the pre inverts phase.I cannot speak for your preamp,but in 99% of the cases,the(electronic) method that a preamp changes phase,is not without sonic penalty.
The Helene inverts phase. So both outputs (RCA and XLR ) are inverted, not just RCA.
The difference between correct and wrong phase should be audible.
The reason we ask users to try both and see why they like is, because sometimes their speakers(or amps) are inverted, so using the dac as it...
