I am thinking in getting into an electrostatic system. I know I want the SR-009 for sure and in the long run I want the RSA A10 Thunderbolt to drive them and use it as pre-amp too but the combo is out of my reach right now.
I am planning on buying the SR-009 and a lower amp as first step to later upgrade to the A10. My question is, should I buy the SRM-727II ($2,200) or should I buy the WEE to use it with my Threshold T50 (50 watts/ch pure Class A) and Threshold T2 pre-amp?
I am using the T50 to drive the HE-6 and it does an amazing job so with the WEE I can have the SR-009 and HE-6 connected to it.
I know it is $1,500 difference but regardless of the cost difference which one do you think will sound better? Hopefully I will get the A10 in a year or so.
I can only say that the Woo-Wee (500 USD) with an OTL tube amplifier for headphones (Audiovalve RKV mk2) (2.200 EUR) (http://www.audiovalve.de/rkv/audiovalve%20rkv%20mark2.html) and with the Stax SR-009 headphone sounds particularly good, at least as well as the Stax SRM-727II amp (3.000 EUR) boosted by a regenerator of sector PS Audio Plant P3 (3.000 EUR) and barely less that an Eddie-Current Electra amp (with racing tubes) (4.500 USD), as shows very well this objective study. http://www.head-fi.org/t/681814/amplifiers-shootout-for-stax-009-eddie-current-electra-audiovalve-rkv-wooaudio-wee-stax-srm727-srm007t2
I can add than the use the same Stax SR-009 headphone used directly on the Audiovalve RKV MK2 amp (NB : Woo-Wee box is used only as an simple bias voltage generator (580 Volt DC), and the two transformers (multiplier of voltage 1:50) of the Woo-Wee are bypassed) will even more far away : gain of transparency, more natural sound and more presence (especially if Siemens tubes are used for the amp RKV) and, in my opinion, more natural than the Electra amp, and with might better synergy that the BHSE amp for use with SR-009 (NB : I do not speak here of SR-007 mk1 headphone where the BHSE amp seems untouchable).
