Figuring out how to switch REL Precedent’s IM bandwidth to more suitable for Stereo operation I was wondering about something else. The 250kHz window though which the REL Precedent looks to the FM band is might be fine for DXing or having good selectivity but from what I see in context of another tuners 250kHz is too narrow range for producing best sound quality. All modern tuners have IM filters tined from 430kHz to 150kHz. Sansui TU-X1 has Wide-400Hz and Narow-200Hz (in fact it sound VERY nice in Narrow). Yamaha 7000 has 430kHz - the widest and the Yamaha T85 has 150kHz – the narrowest. Sure, with shrinking the capture widow makes the selectively of a tuner go all the way up but also the sound quality goes all the way down.  The T85 in Ultra Narrow mode has a phenomenal selectivity but it sound like MP3 player. Tuning to a good station in the Super-wide on T85 mode adds a LOT to sound quality compare to more narrow modes….

 So, why to have in the REL Precedent the 250kHz capture window if wider ranghe would add more to sound quality? I do not need this tuner to catch the live transmission of Florida radio stations broadcasting the high-speed chase of local drag dealers. I needed it to get max sound quality from my very local stations. So, the REL Precedent will be converted to 400Hz IM bandwidth – and it might make it to have the Sansui’s sonic space and the Sansui’s bass. (Bass is dying first with shrinking of IM bandwidth as I can hear).
