I'm very interested and I was wondering, would a K1000 capable amplifier be sufficient in driving the H2? Since I'm already a K1K owner, I like the idea of reterminating a H2 with a 4 pin XLR and using my existing tail-end adapter off the speaker taps of my integrated SET. Would this be a possible solution to bypass/ eliminate the need of the TR2 transformer?
My apologies if this has already been discuss before.
I fear you may be disappointed. Driving the H2 is like driving an electrostatic headphone except without the bias voltage, its inherently a capacitor, and a big one. The K1000 and the H2 are exceptionally difficult amplification loads, but in very different ways.
I hope that there is a power amp out there that'll swing the ohms, I really do, and its ultimately only the brave experimentation of head-fiers that will discover the truth. I look forward eagerly to hearing your comments!
Brother, Duggeh ...
In addition to these possibly biased ears, there will be the entire Florida crew giving a listen at our October Meet. Grab a plane and come over! We'd love to have you.
Dear group-by mennbers,
The TRS model's sales and production were ended.
Moreover, the first production lot of the XLR model was sold all.
Thank you to head-fi members who interested in our productions.
The group-buy continues though the next run of production will be shipped in after 20 or 30 days.
I think the panel of this group-buy to be closed on the number in the back day, so E-mail the report directly to the following mail address, please.
And I must reply jcx san.
1. sencitivilty of H2 ; 96dB/100Vp-p
2. H2 circuit; vibration board is composition of three ways.
The electric capacity of every composition are (50nF+8.6kohms+
thermal protector) +(5nF+4.3kohms)+(2nF+20kohms), which are
connected in parallel. Resistance and the thermal protector are the series
3. The electric strength of the vibration piezo film is 1kV.
4. The electric circuit of TR2 is appended with the explanation.
However, I don't understand whether to attach it well.
Please inquire directly if you do not open it.
5. And about amplifier; My acquaintance's another company is scheduling
sales to a preamplifier in October . It is the preamp for speakers and H2
exclusive use terminal attached to the preamp. Sales to foreign countries
seem to be considerably difficult because a Japanese specification.
Please inquire of the following mail address when you want to know the
preamp in detail. He,Mr.BaBa understands English.
You can here how he is thinking about sales to foreign countries.
Thanks and Best Regards,
