    Lol... Indeed, it would help run it in!

    No reason why not, but it would have to be later in the year when I've got less on. Steve's system looks great, and I'm sure sounds it, but if it were mine I'd need some 'big boy' speakers... Couldn't live with small stand-mounts, long term.

    Just not necessary or required in there. Would take up too much real estate. Unlikely to produce a better result.

    Suspended floor acts as a sub and the level of bass in there is more than I have heard from Raidho C1s at shows.

    My speakers would be a disaster. Some large Tannoys I have known I feel sure would not be good/better than the Raidho's.

    Anyway, here are some thoughts on the system.

    1) The little Raidho C1.1 I have heard many times at shows. They are usually placed in free space well away from rear walls. They aren't that close to the rear wall at Steve's place, but they are in a much smaller room than is usual at shows, and live on a suspended floor.

    They also live atop of bouncy stands. Touch the speaker and it sways back and forth. The speakers are superbly finished and look expensive - probably because they are.

    I have heard larger Raidho's, but I am not sure how much better they'd do in this room. Bass levels, as I discussed with Steve, seem quite generous. I'd rather have a little too much bass than not enough, personally, so this is no bad thing. It may be that because the speakers is only quoted to 50Hz, the bass has been hyped a bit to give it the impression of having some This is a typical thing to do with small speakers.

    Generally, the extension seems OK. The one obvious giveaway was Yello's The Expert, from Touch. There's a synth bass that drops in frequency for quite a long time. I only heard about what seemed like a third of it. This confirmed to me the speaker really doesn't go low. However, if you didn't know it was there I guess you wouldn't miss it, and the rest of the track sounded fantastic, as that album generally seems to on most systems. I'm not sure what gear Yello use but they are definitely to my mind using some sort of DSP.

    2) The Raidho seems very free from sounding hard with anything that is played. This makes it very, very easy to listen too. There's a lot of detail presented in a very palatable manner, and it genuinely sounds very, very pleasant in this system across all the genres we tried.

    The speakers form an equilateral triangle with the listening position, and there is a nice degree of separation or "freeness" between instruments in the soundstage. The overall presentation has to be described as warm, and with the Nagras heating up the space warm in certainly was. Mind you is was a hot day anyway.

    3) Bass level may also seem generous because of the proximity to the rear wall and corners, and the suspended floor, which was definitely joining the party at higher levels. As I said I'd love to get a test mic in there and see what is really going on. The room has both diffusers and absorbers on the front and side walls.

    4) The Nagra amps seem to match the speakers very well. As Steve says they just sound right. I tend to agree. Steve is just using some cheap Shuguang 845s at the moment, but wants to explore other 845s. As I said, the cheap Shuguang 211s are surprisingly good, but do not compete with the likes of NOS Amperex in my system, so tube rolling would definitely be worthwhile I think.

    5) The Modwright 36.5 I believe has stock valves in - a 5AR4 rectifier and some 6H30s. The website says the GZ34 is an upgrade. If I were Steve I'd be rolling these too, but I have no experience of 6H30s or GZ34 so I have no recommendations. I do find valves to be critical in preamps and power amps though so there is a lot of opportunity to be had here to fine tune the system to Steve's taste.

    6) The TT sounded great on Brubeck but we didn't explore much more.

    7) Great system overall. I'd like to hear the Raidho's on non-floppy stands just out of interest. Easy enough to try - I have something that would do the job.

    Thanks Steve for letting me share. Despite the bass comments the system really was VERY enjoyable and definitely "up there". It is certainly a change from mine, being really quite different. The quasi-ribbon tweeter in the Raidho deserves a mention - it must be one of the least objectionable HF reproducers out there. Well worth a listen.

    Went round to Steve's again yesterday, deaf in one ear due to an ear infection, which is on the mend now.

    Things have changed with Steve now using one of these. Nice.







    Using the one ear, I think I established this cartridge is definitely OK
