post #886 of 1184

Then, Frederic (superfred21), if we remains in the subjective listens ; for you, what is the best of these two amplifiers to associate with the Abyss ?
The full symetric amplifier AudioValve RKV mk3 of Pierre (at 4 K Euros) or the Eddi Current Balancing Act that you possess (at 4-4, 5 K $, depending on the choice of the tubes) ?

In my very humble opinion, that Audiovalve is an absolute monstrosity...

My humble opinion starts with f and ends with ugly.

The large tubes just have to sound better................

 

It's all in the expectation bias.

Pierre (shiva) and Frederic (superfred21) what do you say of this:


For Pierre, Abyss + AudioValve RKV mk3 is the best system ever listen (for him). 


According to Pierre Paya (for Casques-Headphones), the mk3 (symetric) AudioValve RKV is a worthy successor to the legendary AudioValve RKV mk 2 (asymetric) and is one of the best and most powerful amplifiers for headphones ever built. http://www.audiovalve.info/rkv3/audiovalve%20rkv%20mark3.html and http://www.audiovalve.de/rkv/audiovalve%20rkv%20mark2.html
It is more powerful than the also legendary Eddie Current Balancing Act and could be one of its direct competitors (at same price) for use high-end with the Abyss.


There where I am getting, Pierre said that listening to the Abyss with the mk3 RKV is better than that of the Stax 009 with SRM 727. However the mk3 RKV uses a transformer in mode "transformer mode" for a < 100 Ohms load) (with his internal impedancer) to be properly used (in impedance) with the Abyss (of 46 Ohm of impedance). However this transformer (internal impedancer in the mk3 RKV) alters the quality of the audio signal (like any transformer).
Conversely, Stax 009 can be directly used on an RKV "in OTL mode" (no output transformer on the audio signal), with a gain of transparency and presence obvious compared to the classic mode using the Wee impedance transformers 1:50).(NB: the Wee is used only to generate the bias voltage 580 V DC on the 5th pin on the Stax headphones).


In this specific operation of the RKV on the 009 with the mode direct "pure OTL", is it not impossible that the 009 return to top on the Abyss, at least for the quality of the medium and the treble (not for the bass) in terms of transparency and presence ? over the Abyss when it is used in the mode "transformer mode" (with impedancer) of the RKV (mk3 with the impedancer internal or mk2 with the external impedancer).

Doesn't Pierre sell the Audiovalve?

In France, Yes.

 

For tubes (for my mk2 RKV unit) I recommend the Siemens Roher PCL805 (at 34 Euro per tube), more neutral and more accurate than the base tubes provided with the unit.

I don't care about the opinion of someone who's got something to sell...

The french market is currently very targeted for the Abyss; difficult to escape at this headphone on HCFR , its hype and this slogan "The Finest Headphones For Musical Reproduction". To believe that the electrostatics headphones are coarse :D.

JPS Lab (or AlterAudio, the French importer ?) is pretty presumptuous If he thinks that more expensive = better.
