Well, yesterday was supposed to be the day but PriceJapan.com says it is now delayed to late May.
Anyone have more informations about that delay?
By curiosity I looked at the Fujiya Avic website. It is not easy to navigate on it but I could not find any reference to the SR009?
I have been told that the Stax production capacities are not affected by the earthquake. I think the Stax company is based near Tokyo but hopefully the parts are build somewhere else?
happy for you I hope you like them;)
You really need to hear these phones on other amps to be sure that this set-up is satisfactory. In my trials the SRM3 amp made an 007A sound mushy but listenable, the SRM1MK2 was fairly decent, the 717 moved these phones up to another level and the BHSE to yet another level. I lust after a BHSE but with kids starting college I could not get away with such a purchase.
Subject: Amplifier for SR-009 and electrostatic headphones in general.
Currently, I’m listening to my Omega SR-007 phones with a SRM-252. IMO, for low & normal listening volume levels, the result is more than satisfactory.
SR-009 is now on order.
The circuit topology and solid-state devices used are essentially the same as the SRM 323 amp (I have the schematic). Mainly, what’s different is the power supply, and the output stage bias – more voltage swing and current drive capability.
An electrostatic transducer basically presents a capacitive load to an amplifier. For a given sound pressure level, output drive current is proportional to frequency, or rate of change of voltage (I = C dv/dt).
I feel that heroic output power capability (high current * voltage) provided by the far more expensive power amps is not really needed at normal listening levels (for me, anyway) – as long as the electrostatic amp behaves well with very low distortion at small to moderate voltage swings. I’ve listened to tube (I have a Stax tube amp also) and solid state amps, and feel that the well-designed Stax SRM-323S should offer all the amp power I need, even for the SR-009 (yes, perhaps a radical opinion). Even the lowly STAX SRM-252 amp is direct coupled, with no coupling caps in the path – IMO, a remarkably nice sounding design. I understand that the SRM-323 is well regarded ...
I used to feel that tubes were somehow naturally better than solid state – not any more.
I've read that solid state might be more compatible with the new SR-009 compared to the previous Omegas (initial listening impressions were posted, as I recall)
