Επανέρχομαι, ίσως σε ενδιαφέρει: Κάποιος στην χρυσή ευκαιρία (με τηλέφωνο 6945/912485) έδινε (τελευταία δημοσίευση 28/12/2008) ένα Kenwood ΚΤ6040 στα 80 Ευρώ.
Από δε το link που έδωσα στο post#45, διαβάζω:
"The KT-6040 was the successor of the KT-7020, which was the higher model of the KT-5020. The 6040 is an excellent tuner and, as mentioned by someone else, a sleeper. It is, IMHO, superior to both the 5020 and the 7020, with the 7020 being superior to the 5020. I've checked the schematics of the KT-5020 and the KT-6040, and I see many differences. The 6040 has 5 gangs (I think), 8 ceramic filters and 3 IC filters, and the distortion cancelling circuit is much more complicated. Also the MPX chip is better in the 6040 (LA3450) then in the 5020 (LA3401). The 5020 has a combined AM/FM IF IC (LA1266), while the 6040 uses seperate IC's (LA1235 and LA1245). The KT-6040 is a new design, stepping away from both the KT-5020 and the KT-7020/KT-990D." Our contributor Rudy adds, "I also recently owned the KT-6040 and it's a definite sleeper. In stock form, it's already excellent for both sonic and DX performance. This should be a top-rated digital tuner, on par with the Yamaha T-85." And our contributor Sinan says, "I never heard a tuner with a better S/N ratio! Also extremely low distortion with an amazingly quiet background, but the Sony ST-S555ES has the edge in detail and stage width/depth."
ενώ για το 7020 με το οποίο το συγκρίνει, διαβάζω:
"Kenwood KT-7020 (1990)
You can search, but you're not likely to find this big brother of the renowned KT-5020 on eBay (U.S.) because it was sold only in Europe and Asia. Our contributor Fabio says, "The circuit of the KT-7020 compared to the KT-5020 seems quite more complicated with the distortion canceler circuits, discrete components MUX (multiplier, op-amps, etc.)." Our contributor Jeroen adds, "Strangely enough, under the hood the KT-7020 is the same as the KT-990D. I own both the 990D and the 7020 and the PCBs are exactly the same with exactly the same components. My hypothesis is that the design of the KT-6040 was meant to be for the KT-7020, but it somehow got delayed and due to time constraints they took the design of the 990D and used it for the 7020."
