  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

    No. I was making reference to some of the ML cartridges, namely the Shilabe and the Wasa which have a vertical compliance of 8×10-6cm/dyne. These have a resonant frequency of >12Hz with a 14 gram effective mass tonearm like the TW 10.5 which is very likely to mistrack. On any tonearm less than 14 grams EM the resonant frequency will be higher! Actually I think ML vertical compliance figures for some of their models are somewhat enthusiastic as I have had these mistrack on a 20gram tonearm! I mentioned this as something to be aware of when matching a ML cartridge to a tonearm.

    Having said that the Kensui and Madake are more modern designs (<5 years) and have a vertical compliance of 9×10-6cm/dyne which is more suited to current tonearms and this brings the resonant frequency down to 11Hz (with a 14gm tonearm). This works with the TW tonearm without any mistracking and sounds full and dynamic. Normally I aim to get the resonant frequency down to 10Hz so there is a couple of Hz leeway either way.
    Check out the show reports in the USA and you will see the TW10.5 tonearm and the Madake are used a lot together, as are the ML mono cartridges too.

    Interesting thread from which I have picked up a lot. If by SN2 you mean Supernait 2, then I think that dropping 3-4K on a cartridge is taking source first a bit far. I would seriuosly consider better amplification before taking the source to such extreme. If not S'nait then please ignore.

    I will ignore in any case :)

    Yes it is a SuperNait2, fronted by a very good analogue front end. It is completely capable of revealing changes to that front end.

    The excellent Guildford Audio (whose service I heartily commend) will be lending me something interesting in the near future.

    Ignore away mate. Your choices after all. Do you have a dedicated phono stage? I might have missed this.

    I will take your word on Guildford Audio. I wish I was a bit nearer them or any other decent Naim dealer for support and demos. There is no such choice in Greece! I have to squeeze in shop visits on trips back to the UK which is not ideal; sometimes buy blind. There is a Hifi cabal here but since the Greek crash, shops do not hold much if any stock. Do let us know about your interesting loaner from GA.

    No post-olive Naim integrated or pre has an internal phono stage. I have an Aurorasound Vida, which I admire tremendously for its neutrality and midband insight.

    Greece is interesting. I recall a band of ultra-high end enthusiasts there (and perhaps some similar small scale manufacturers?), at least pre-2008.

    Guildford Audio had to take my SME away last week because of a bearing fault - for which I was probably responsible. I was terrified that I might be looking at the thick end of several months to get it back. But turns out it's coming back at the end of this week, quite possibly with a Rosewood Signature attached. Great service from them and SME.

    I am not familiar with the Aurorasound brand and will have a look at the Vida. When I went down the Naim path I bought the Stageline just to keep things in the fold and also as I was not able to trial alternatives. I was in Yemen at the time so bought blind.
    For me the vinyl side was a legacy issue just because I always owned a “record player”. In the last few years I have been taking it more seriously and now buy more vinyl than CD. I replaced a P5 with the RP8 and added the Superline. As I had a spare Supercap after going 252 to 552, the phono stage will remain for some time. Again mainly due to limited options here to try before you buy. I did find a Rega dealer in Athens recently and will be in touch about hearing the RP10.
    I think the hifi gang are still clinging on here. The local aficionado website is not that active anymore. There was a “High End Show” here last October. It was a bit haphazard being a local event but fun nonetheless. The dealers were all of the same view that people were not spending anymore on such luxuries and hence the low stock levels which I can understand. There is no real secondary market either.
    Good news on your SME. I hope it comes back fully fettled and let us know how you get on with the Rosewood. I’m still faffing with loading settings on my Apheta. I see you play bass too. I have the same hobby but no live gigs here unfortunately for me. Too old to be in a boy band these days.

    BODGER, I was very ha[ppy indeed with my Supercapped Superline (+Burndy & HiLine) into 552. It became a real hassle, though, when I changed decks and went two arm/cart's.

    One big design fault of the Superline (for me) was the difficulty of plugging in /unplugging, as there should be grab handles incorporated.

    However, all gone now in favour of all valved amplification and built-in phono stages ( better* and very different with my Quad 2905 'statics)

    * More holography, ambience and dynamics.

    Mike, I hear you about the plugging issue.

    I have only heard the 2905's once. Very impressed.
