re: my tu-x1, yes, it's a fine sounding beast.  unfortunately, i cannot give you any info re: how it sounded before mods; when i bought it, it was japan-spec - 76-90mhz tuning band, 50us deemphasis and 100v.  i had it sent directly to joseph chow, a former kenwood tuna engineer, who now owns audio horizons/component plus; a mfr and refurb/mod outfit.  i had him conwert it to usa spec, including the tuning dial.  and, as long as he had it, i had him refurb it and mod it, per his premium mod package, which can be seen here: http://www.componentplususa.com/pages/upgrades.html it's funny, he actually has a pic of my tuna on his main component plus page - i recognize it cuz he sent the pic to me; i told him it was unacceptable, i wanted the tuning dial to look exactly like standard production, not the black/white dial as shown in the pic.  so, he had to re-do the dial.  http://www.componentplususa.com/pages/componentplus.html

Hm, the conversion from Japan-spec to US-spec was a hell of a work! BTW, do not agree with all modification they propose.

anyway, this is a fine sounding tuna.  but, i am not sure it is better than my stephen sank modded and refurb'd harman kardon citation 18 - a direct a-b would be necessary, and i haven't taken the time to do it.  i suspect that my tu-x1 might even be able to be taken further; i have seen an on-line documentation where someone re-built one practically from the bottom up, w/only the best parts... (stephen sank's home page): http://www.thuntek.net/~bk11/home.htm

I do not know anything about Harman Kardon and I quoted it in order to keep your comment in this thread.

i suspect the tu-x1 *might* have a tiny edge in the lowest bass response, but if it is, it ain't by much.  considering how relatively cheap the hk 18 is, even after mods, i'd recommend it as a freaking bargain.  as is the tu9900, after mods.  the tu-9900, i know gives up the tiniest bit of low-end bass to the tu-x1, but it is so much nicer looking, and a bit easier to place on a rack - the tu-x1 is huge.  now, i also had a stock tu9900; mods improved this one a *lot*.  the one i have now was first worked on by mr chow, then its owner sent it to mike williams at radio-x-tuners, for further filter mods. http://radioxtuners.com/

I heard a lot of good comment about modified TU-9900. I never had it and never heard it. I need to look at it’s circuit to see what it have in there.

now, i also have read with interest your comments about the r&s ballempfanger; i once owned (since sold) a telefunken ebu 3137/3 ballempfanger; it was a fine sounding and receiving piece, thru a slightly modded studio-12 stereo mpx decoder, but it was no better than my hk 18... http://www.ak-tubes.de/Tuner/Ballempfaenger/Telefunken_EBU/ebu.htm have you ever heard a rotel rht-10?  my stock unit sounds wery nice indeed; i have heard that, after mods, it is likely even better than an accuphase t109v, sansui tu-x1 or kenwood l-02t.  i am wanting to get mine modded.  and, i also want to try an accuphase t1000; thru a dac, it is supposed to be a significant step up from the standard "holy grail" tuna offerings...

I was thinking about Telefunken EBU 3137/3 and was very attracted by nevistor front-end but studying circuit my advisers did not recommend me to do there as it was more primitively made machine compare to R&S. I never had it as result. I was not a big fun of Kenwood L-02T. The folks from FM Tuners made from it some kind of kitsch cult but in fact I feel that it was not good tuner that turned in absolute shit as soon PLL was activated in narrow mode. I did not heard the Rotel RHT-10 and also would like to heard the new Accuphase T1000. It is kind of sad, the US rep has none of them in stock, no trail program and no ability even to support conversation about FM and tuner intelligently. The tuner is 6K and to buy it blindly from a completely moron is not a good idea. I know that there is in Boston two Accuphase T1000 but I do not know those people. It would be very interning to hear what this Accuphase does.  Hey Bostonians, if you are one of the guys who have Accuphase T1000 then get in touch with me and I will try to make the acquaintance mutually beneficial.
