At last... (Audiolab) - part V

Bought WHiFi to check out the mdac review today (£4.65, what a rip-off). It sounded like they wanted to give it 6/5 (or 5/5 and the rest 4 or less) but didn't want to annoy other manufacturers (advertisers).

John, is it still looking like mid october for the mdac?

I just read the review quickly in WHS :eek:. £4:65? got to be kidding....

I bought mine from the newsagents across the road though so wouldn't wanna do that to them. I imagine i'll be vaguely entertained by some of the reviews though and i've got nothing better to do as I'm sick as a dog ATM......
 
Chinese valve amps can be good but they need to be looked at by a UK-based engineer who specialises in valve amps to ensure that they are safe to operate on UK voltages - up to 253 Volts. Chinese valve amps are barely safe at 220 Volts. I can recommend Anthony Matthews of Tube Distinctions.co.uk who built my amps and will be modifying them again in the near future.

Nick (lurcher) of audio talk and AOS is also a good bet.

Some of the World Audio Designs amps are also very capable and are often available ready-built s/h.

Personally I am a fan of KT 88 output valves and their derivatives (6550, KT 90 and KT 120) for their "real world" capabilities in terms of being able to reproduce all kinds of music and drive a wider range of speakers.

Thanks for the advice Steven. Will bear it in mind once the MDAC is purchased and settled in. Can then start to plan for the next move in earnest.
 
If the MDAC is as good or better than the CDQ (it probably is) then it will punch well above its weight and will shine through rather exotic (valve) amps and reasonably efficient speakers.

You and me both - its truly a horrided place. I've lived and work all around the world, and the only place where I'm worried to walk the streets at night is SE London.

I know exactly what you mean.

My DC's in China (I'm still thankfully in Czech for a few more days or so) - but Keep your DC, we will get it going with the MDAC... (Somehow). I'm interested to compairing DC operation with the "offcial" External PSU (which I'm going to start designing today).

Okey dokey, i look forward to it. Enjoy Czech for a few days more, As a matter of interest, how many times a month are you moving beween Europe and China?

Steven.
 
If your really interested in one, then I can bring one over for you - hey maybe I can become the Czech Distrubuter - and then I can complain to the designers.. wait how would that work?...

PM if your really interested - and I will arrange something for you.

Hi John

I tried a PM but you're full again. I would like to take up your offer to deliver a MDAC to me in the Czech Republic. A black one please!

I'm a bit disappointed by what I've seen of Czech HiFi dealers. There seems to be nothing outside the very largest cities and they are very expensive - about 50% more than in the UK and not just for the UK brands. Fortunately, for us, Dresden and Chemnitz are close and the dealer choice and prices are better.

Many thanks

Chris Shorter

Generalisations like this are never good. For the sake of accuracy the Chinese valve amps from diy hifi supply have no problems relating to safety as described above. They are entirely suitable and safe for UK voltages.
 
Hi John. I'm on the verge of pre-ordering an MDAC from Superfi. I intend to use it as my pre-amp, but would definitely need A/V pass through analogue input. If I understand correctly from previous posts, this will be possible via an upgraded external psu. Will I be able to buy the new psu on it's own at a later date? Any (ballpark) idea when this might be? Many thanks.
 
Brian,

Those generalisations are made for safety's sake and refer to grey imports.

You can add Puresound to your list of safe valve amps imported from China (and through a UK dealer network.)

The grey imports are not to be ruled out, they just need to be looked at by an engineer in the UK before they are even switched on.

Diy hifi supply looks excellent btw, however I have just checked their section on diy building advice. The equipment is configured for 115/230 volts. For the UK they need to be good for 253 Volts.

If in doubt about this contact Anthony Matthews at tubedistinctions.co.uk who has modified and made safe a number of Chinese-sourced valve amplifiers.

I know, but that isn't what you said. You didn't qualify the comment, you generalised when you said " Chinese valve amps are barely safe at 220 Volts" so for anyone who doesn't already know something about Chinese valve amps they may well be worried by your comment, which is inaccurate.

By the way, I'm in no doubt at all about my valve amp. Whatever it says on the website the reality is it has multiple taps - 110v, 123v, 220v, 230v and 240v, plus my amp was built (with me watching and learning) by NickG, who was mentioned by yourself earlier on. I had previously heard Nick's WAD KT6550 in my own home and really wanted one of those but WAD were unable to supply at the time. I turned to Diy Hifi Supply and Nick knew which amp I was buying ahead of the purchase, I'm in no doubt he would have told me ahead of the purchase if he believed these amps were not safe for UK voltages, plus I doubt Nick would have been prepared to build something unsafe anyway.

Thanks for the concern but these particular amplifiers are not unsafe. You need to make sure what you're posting is correct before making these comments.

For example, take a look at this where you will see mention of :
Power: 105/115/120/210/220/230/240/250V AC
