VHF/FM radio ...

    Must admit that the thought that came to my mind was, "I wonder what you'd make of the 320k aac stream processed into mono. :)

    It's a bit more complicated than that if the transmission is in stereo. The reason being that the L-R stuff still causes the modulation to swing over a large range with its added HF components. So if the IF filtering it too narrow it will distort, and some of that may affect the L+R when the tuner 'averages over' the L-R.

    Despite that, the effect is, indeed, likely to be less distortion than for stereo.

    NAT3 would be a good next step, but mine did need a Galaxy 17 to work properly. I did have it in the loft without too much losss of signal.

    Sensitivity doesn't lower the further up the ladder you climb. As my 01 and the previous 101 are/were very insensitive, I can't imaging any Naim tuner coming close to sensitive. The Japanese were pretty good at this, though. A Troughline I borrowed for a time was almost as insensitive as the Naim, so maybe it's a British trait !

    I suspect the Japanese designed FM tuners more for Japan and the USA than for the UK. That tends to mean a wide variation in signal levels and the number of stations crammed onto the band. People in the USA might want to DX an FM station a long way from the, packed in beside local stations. Whereas for many decades the same set of national BBC FM stations were arranged to give people a better access to them over a fair bit of the UK.

    State of the art in tuners remains up market Japanese ones from around '75 - 85...

    My Yamaha CT1010 which I nabbed from eBay for £60 is a lovely tuner.

    Such as? A Marantz (8B?) valved tuner was very highly rated, but that was sixties. I had, among others, Pioneer, Stereofetic (Leak) and Revox, but they were early seventies and were never mooted as 'top' tuners. Generally, top tuners include Naim, Yamaha (?) and Magnum, all subsequently

    Such as the most expensive models from Trio (Kenwood), Pioneer, Sansui and Yamaha. Revox are up there as well. Naim are not in the same league.
    Leak Stereofetic is good and even better are the 2000 series tuners (avoid the amps they are truly awful) but certainly not in super tuner league. The Troughline was good in its day but crap by modern standards.

    I’ve never really seen Naim as a serious tuner contender. They’re certainly competent but nothing special IMO. And unfathomably overpriced I think.The others that Arkless mentions are certainly up there. My father in law had a beautiful Yamaha year’s ago. He loved it. Often regrets selling it.He now owns a modern Magnum Dynalab.

    I’ve owned a few tuners :) including three different Revox, a noisy Magnum Dynalab 108, the poor Naim 01 and 02 (and ridiculous Ron Smith twig - but then some like structural damage) and Leak Troughline thing, a Marantz 10b, various top Sony, Sansui, Pioneer and Yamaha etc etc (there’s a full list on here somewhere). The ones I kept are a McIntosh MR78, (cost £800 and gets most use), a very splendid Marantz 2130 (£30), a Yamaha CT7000 (£300) which shows how hi-fidelity components should be built, and a Sony ST-5950SD (£50) for sentimental reasons. The rest are gone and with thousands and thousands of internet radio stations from around the globe in up to and including flac quality, won’t be coming back. Tuners were fun, a good insight into house sounds and a real education in hi-fi bullshit (especially UK hi-fi bullshit) but it’s over. Shame about BBC radio. :(

    In the early eighties, the 01 (and its lesser sibling, the 101) was considered among the top few tuners in reviews and magazine appraisals at the time. It is insensitive, but with a decent signal, has a fine, balanced and very natural presentation. It didn't win accolades in its time because it was Naim; it did so on merit. I've no idea about the more recent tuner derivatives, though the 02 is supposed to be good; its predecessor was.

    I had a McIntosh MR78 in for service many years ago and it was very impressive! great build and great sound.

    .aac and Flac don’t light up in a cool way.

    TheDecameron Unicorns fart glitter.

    I’ve still got my SX750 from when I was a student ( inc the Castle Tynes I bought at the same time to go with it). My tuner collection is now whittled down to-
    MD108
    MD102
    Troughline III/ TdeP valve decoder.

    There’s real magic in the sound of the MDs coming through Harbeth speakers and a good amp. You could argue why not just use internet radio but why bother with vinyl either? Both are enthusiast pursuits and will endure I feel.

    Both my four element yagis are a bit battered by wind and time, so need to get that sorted. Problem is they’re hard to find now- the last two were from Maplin.
    Any tips on suppliers most welcome.

    I've long felt that audio playing/recording programs/apps on computers need good-looking PPMs. So have tended to add them for some of my DIY stuff. But for a 'net radio', yes it would be nice if that had a display that mimiced one of the nicer types of old FM tuner and gave you a tuning control that 'tuned' the display from station to station.

    Could even use 'FM' for 320k aac/flac and 'AM' for modest mp3 stations. Or something similar in the form of a 'signal strength' waggle-meter. :)
