hey whatjd, cool - don't bother w/vintage tuna. more for the rest of us! ;~)
seriously, you need to listen to several kt-5020's before you can make a determination as to how one should sound. or, at least get yours properly serviced & aligned. tuna's are far & away the one piece of audio gear that most needs to be serviced & aligned before a serious audition. don't get me wrong - i am not defending this tuna - i have never heard one. but i know i wouldn't be so quick to judge it, based upon one un-serviced sample.
again, the shootout list is only one person's opinion, in one person's rig. i certainly have disagreements with the shootout list, but that does not mean it's patently off base. example: while i *did* think my revox b760 was fantastic, i like my philips ah673 & mitsubishi da-f20 a bit better. and my revox b261, which was thoroughly panned on the shootout list was *identical* in performance to the b760 - i decided to keep the b261 & sell the b760. and, the tandberg 3011a *sucks* - i was happy to return mine in exchange for the b261 i replaced it with. :>)
as far as "ferrari for fiat" tunas go, here's a list of those i have personally tried that all cost me <$100, that i feel can stand shoulder to shoulder w/the best, sonically. some are not the most sensitive, tho:
nikko gamma 1
philips 185
hitachi ft-8000
jvc bx1100
aiwa 9700
technics st-8600
stromberg carlson sr445 (used w/mpx stereo decoder)
fisher fm90r (used w/mpx stereo decoder)
sherwood s3000-III (used w/mpx stereo decoder)
i have not tried the hitachi ft-920, or the mitsubishi da-f30, but i suspect they, too, are winners, based upon comments of those i trust.
ymmv,
