Japanese Audio

I’ve been using them as well.
The model is the TA-S01 - If recall correctly they said it was 4 watts(?)

Never experienced anything quite like it.

@jkeitel,
If it is rated at only 4 watts output power, that suggests they are using ’very’ conservative operational points for the 300b. This usually means two things,
1 Prioritizing sound quality over higher power capability.
2 Exceptionally long tube life.
I bet it sounds utterly gorgeous!!! This amplifier utilizes the esteemed Japanese Tamura output transformers.  Looks very well constructed.

this has been a very interesting thread so far, thanks gents

robertrs,

A friend of mine thought about Onken cabinets for his Great Plains 604 drivers, but, the Hiraga design and others recommended for this driver are enormous and extremely heavy; he went for a more conventional bass reflex cabinet. 

I personally like Onken cabinets; my speaker has twin 12" woofers in an Onken cabinet.  I got my Western Electric 713b midrange compression drivers from Japan (most of the best vintage American gear is now located in Japan, Korea or Vietnam).  I am a big fan of the same kind of gear prized by the Japanese and I particularly like their old school speakers inspired by US brands, such as the compression drivers and horns that use to be made by Yoshimura Laboratories; they are consistently terrific sounding even though they are made in a crazy array of sizes and configurations.  The current manufacturer G.I.P. Laboratories still turn out terrific Western Electric clones, but the prices are unfortunately crazy high.

I have also liked Japanese electronics from Kondo, Shindo and Zanden.  Many years ago, I bought a pair of Stax Omega II 007 electrostatic headphones (still own and use them with the Amercian-made Blue Hawaii SE headphone amp).  When I took them home, they just did not sound as good as when I heard them at the dealer.  When I asked the deal why that was the case, he pointed out that I auditioned the headphones through a Kondo M 10 linestage and I could never realistically achieve the sound I heard with anything less.
