    Oh my, oh my - Aries Cerat Helene DAC

    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. Best Stavros

    What are the advantages/disadvantages of different amp topologies?

    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 Best Stavros

    What are the advantages/disadvantages of different amp topologies?

    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...

    What are the advantages/disadvantages of different amp topologies?

    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...

The first Pondera was designed in 2011 and was demoed at the 2011 Munich show. In my ears this was...

    Aries Cerat Ianus Essentia Owners thread

    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...

    Aries Cerat Ianus Essentia Owners thread

    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...
