Hi Eric,
To be more precise it is this message when he speaks http://www.homecinema-fr.com/forum/post178055060.html#p178055060
I also think that the 009 had no amp at its height.
But it must be admitted that the Abyss was preferred to 009
Now that does not mean it is better or worse.
Everyone is different.
For example.
Much people love "call of duty" or online gaming.
Personally I prefer a good single player games
( S.T.A.L.K.E.R. for example )
Good evening (or good morning) everyone,
Jonathan, I learned two interesting ideas in this meeting of headphones in Paris regarding the differences of plays between the Stax SR-009 (+ SRM 727 amp) and the JPS Abyss (+ RKV-mk3 amp), the first idea comes from Sol23 which I quote word for word what he said (translated into English):
" Personally I found that the Abyss and SR-009 offered two different listens, this is the first time I listened to the SR-009, it seemed very right, clear and open, in short it is a listening quite analytical and ethereal, while the Abyss seemed to me propose a more matte and liquid, with a wider stereo spatialization sound. I do not know if others share that impression but the Abyss makes me advantage think at the SR-007 with his presentation very "laid back". "
This interesting comparison would show why it is difficult to compare these two headphones to the quite different listens (the 009 headphone vs Abyss would give a listen any also different than that of the 009 headphone vs 007), knowing that the Abyss is getting nearer over the 007 headphone by its duller sound and "laid back" and would fit perfectly to the Jazz, while the 009, clearer, straighter and probably truer in tone in the treble (violins) would correspond better to great classical music ensembles.
The second idea comes from Skywalkerciel who wondered about the role of the amplifiers used with headphone Abyss and 009 to explain (in part) the difference considered subtle between these two headphones: quote (translated into English):
" you summed up well the difference (between the two headphones) but I'll add 'greater body and matter in the tone (timbre) (for the Abyss) is what has tipped the balance in favour of the Abyss over the 009 for me.
The 009 remaining in my opinion the best headphones after the Abyss of all those I could try but I wonder a bit about the quality of the amp? i.e. are they (amps) do not also have a role in these subtle differences ? "
Here, let me give an explanatory hypothesis based on my own experience with these amplifiers Stax SRM-727 and AudioValve RKV (mk2 or mk3): RKV amplifier used with a large load (low impedance), either with the Abyss (impedance : 46 Ohms) or the 009 + Wee (impedance seen by the amplifier estimated at between 30 and 60 ohm) ; this low impedance will solicit the tubes of RKV in amperage (while these old TV tubes are instead optimized for high impedance > 2000 (Ohms), resulting in harmonic distortions more elevated with a sound more thick, dense, rich and matte.
Conversely, the same amplifier RKV used in direct mode on the 009 (with a headphone very high of 145000 Ohms impedance) as well as the 727 SRM, dedicated to the Stax headphone will give a sound much more light and air, with less harmonic distortion (tubes used mainly in voltage).
Some amplifiers for electrostatic headphones with a denser sound (more colourful) and very dynamic in the grave could perhaps give a closer sound aesthetics of the Abyss (e.g. RKV - Wee using the transformer of the Wee (not in direct mode), who had obtained the best listening on a jazz record compared to 3 other amplifiers (Electra, SRM 727 and SRM 007 t2) during the comparison of these 4 amps (published on Head-Fi) with a sound more mate, fuller, while being very dynamic in the bass.
