Note that the number of gangs can get to as high as nine with a single RF stage, so it is not an issue of lower cost by going to a single RF stage." The same can be said of the Sansui TU-9900 and TU-X1 and the Yamaha CT-7000, which have two RF stages while those companies' later designs do not. The Kenwood 600T and 650T, KT-7000, L-07T and L-07TII have two RF stages. Double- and triple-tuning also costs sensitivity since these have bigger losses than a single-tuned circuit.
The KT-3300D, L-02T and L-1000T have passive mixers for improved IP3 rejection, at the cost of sensitivity. The KT-9XG, KT-1000 and KT-3300D, like the Pioneer F-91 and F-99X, Sansui TX-701 and Yamaha T-70, are only single-tuned at the antenna and are double-tuned after the single RF stage. The L-02T is double-tuned at the antenna and quad-tuned after the RF. The L-1000T lets you bypass the single RF stage, as do the Onkyo T-9090 and Rotel RT-990BX (which is the same as the RHT10). Here's David with some further technical information on Kenwood and other tuners: "The KT-1000 has one RF stage, as do the KT-3300D, L-02T and L-1000T. More thanks to David Rich for his summaries of detector and MPX circuits for many Kenwood tuners. Our Kenwood brochures page has images, information and specs for many Kenwood tuners and other components as well.
