I would try Yodibashi Camera or Hifido, as vendors. Yodibashi is an amazing electronics department store, the likes of which do not exist in the USA. Problem might be that almost no salesperson speaks English. Hifido does have an export business and does speak English.
I liked and agree with almost everything that Raul wrote in his most recent post. Interestingly, I see nothing in there that suggests that one could not gain a great deal of pleasure from a Viv tonearm or that a Viv tonearm or some other underhung tonearm might work better in general than a good overhung tonearm. This thread has devolved into an age old argument between people who go by measurements (or believe they do) and people who go by sensory input, when it comes to judging audio gear. It’s an old argument, and it will never end. In this instance, I do not see a reason for acrimony. We are all after the same thing. I am only urging an open mind. Furthermore, I would venture to guess that neither Raul nor Mijostyn is actually making measurements of his audio gear and the signal that comes out of them. They are most likely going by data supplied by manufacturers and their own considerable funds of knowledge about electronics and distortion. But history is replete with instances where measurements lie. In the early days of solid-state amplification, we had amplifiers that measured harmonic distortion in the order of .000001%. The problem was that when people listened to them, it was obvious that they sounded at least not so good if not also terrible. And this was in comparison to tube amplifiers of those days that produced much more harmonic distortion and had much more limited bandwidth, etc, by actual measurement, but were unmistakably preferable for listening purposes. (Probably not everyone agrees, but consider the Phase Linear 700 amplifier.) So I urge you not to be a slave to one particular parameter, TAE in this case. Just listen. Now Raul's and Mijostyn's listening is evidently of a superior quality to the rest of us. And to some degree this can be true, because they are both very experienced audiophiles (never mind about the definition of an audiophile) , and over many years, they have trained their ears to listen for what they perceive to be a sound that most represents reality. Actually this sort of "training" is a natural process for the few of us who first of all attend a lot of live music events in concert halls and clubs and second of all own elaborate home music reproduction systems. The brain is constantly comparing the two kinds of experience, and if you care enough you want to bring the real one into your home. But I urge both of them to take a look at themselves and realize that in the end they are listening for something they like, so there's nothing wrongheaded about the "I like it" approach, even when others disagree. (Ten years later, anyone's "I like it" might be a much better informed opinion than it is today, if you continue to develop your listening acumen and your system.) One could argue whether either Raul or Mijo has superior judgement based on listening skills, but they are just like the rest of us, some of whom are more canny than others because of putting in the work. Even experienced audio professionals, and I know a few, guys who can and do measure with instruments, because they have to make a living selling good sounding stuff, are nevertheless striving to figure out what sorts of measurement actually correlate with that sense of verisimilitude that any good and eager audiophile is seeking.
