I had a chance to listen und compare one of he best HP Systems. Fort he comparison i took my riviera aic 10 bal. and abyss 1266. Thy host system was accupase cd 720, accuphase pre 290, and A50V LST (lundahl Transformers) and stax X9000 and Orpheus HE90 (also via LST). Thank accupase pre we were able to listen to all 3 HP at the same time (we only have to adjust the volume).
We have only listened to 4 music pieces (Kari Bremnes – voice, Debussy/Zimmermann – Klavier, Hotel California, Stravinsky – Orchestral work) and changed the HP after every piece of music.
I would say. It was a hard work!
But also very revealing. At the begining i had also chance to compare Stax 009s to x9000 but we layed 009s by the side after a few minutes as it was simply another leage. In comparison to x9000 it was bright, technical, shallow stage, too light and above all listening to stravinsky was a torment.
Firstly i must say i am very pleased with my riviera/abyss combo and i regret
listening to stax x9000. In this system (accupase pre + power amp/LST) the stax was better hands down from the very first second. In this system(!) i found the x9000 to solve every weakness the electrostatic HP had. The music had a body, it was never to bright, it was detailed as detailed the music can be. It was spacious and… the bass was deeper and had more weight then my abyss/riviera combo! I was simply blown away.
Whats important ist hat we were compareing abyss/riviera to x9000/accupase pre/A50. As we were ready to compare the both systems we have also connect Abyss directly to accupase pre/A50 combo and voila. It was all there almost as with LST/X9000. It is hard to describe but the music was vibrant, mids were richer as with riviera bass was deeper, the music shined. Ok. Mayby it was a tiny little bit coulored but never unnatural, fat or too slow. It was a spectacular, it moved you into the music. It was realy something. And still x9000 was better, more natural, better mids, better highs, better bass better everything. Mayby a space, the air between the instruments was a bit more with Abyss, but with X9000 there was more connection between the instruments.
What about the sennheiser HE90. In comparison to X9000 it was bit more polite, not quite the energy of attack, and the stage a few meter furter away. If X9000 was 1 row in a concert, tha HE90 the 5. The bass was deeper and bloomier on sennheiser. All in one the same leage but different presentation. For long listening session i would pick up orpheus.
more to come…
