I see no convincing evidence that you are reporting anything but placebo
effects.

Hello Arny, hope you are well. What can I say about aural phenomena except you
have to hear them. Of course you may or may not hear any difference, and I
quite agree that blindfold testing can elimanate several effects we 'think' we
hear. I am a psychologist, and I do have a healthy respect for the nature of
testing situations and the fallibility of results. There again, it was
experiments in perception and in particular hearing thresholds that kicked off
experimental psychology in the 1850s in Germany.

Given that you seem to affect sighted evaluations, which can easily be
totally fallacious, don't you feel the need to support your claims in a more
reliable way?

So, then where are your blind listening test results?

Apparently, you lack sufficiently healthy enough respect to take any
positive steps to deal with the situation.

and in particular hearing thresholds that kicked off experimental

That all said, when are you going to actually do something about your
situation?

Good question, but the question that precedes it is 'how'. To set up a blind
test, which I would gladly do, I need two people, and I live alone. Any ideas?

Actually, Arny, you may be able to help me here. Now, I assume that you are
perfectly capable of doing all your measurements yourself. But, I'm also
assuming that you do listening tests. So how would you do listening tests if
you are alone? If you have developed any particular systems I'd appreciate
knowing about it. Cheers, Andy

Well.

My YaQin MC-10K came today.

So did I.

I've just got it connected up to the CD player and it's "settling in"
now.

It's MUCH bigger than the Ebay pic led me to believe. Lovely finish
and general layout.

Total of 11 valves including 2 like "bargraph" ones which I _ASSUME_
are there to show me the bias on the o/p valves or something. When the
two bars "meet in the middle" I assume it's coming out of class A, but
that is a total guess. Quiescently (music silent), the bars at top and
bottom are still "half length", i.e. not short or zero length. It must be
some kind of bias indicator to show when it's leaving class A. Nice to
have,
actually.

Anyway the amp is ****ing gorgeous to LOOK at.

I got stung for 27.64 of customs charge on delivery, which brought the
total
cost to 250 (Ebay final price) + 80 "shipping" (hmmm..) + 27.64 = 357.64.

Don't care what anyone says, it's a HELL of a lot of amp for 350 quid.
Claims 50W into 6 ohms, so about 40W into 8 ohms I guess.


OK Martin, it falls to me to say 'Well Done'!! :-)

You went after a valve amp with an impossibly small budget and got one!
Enjoy!

Now, a Reality Check (*someone's* got to do it):

The amp is (presumably) hand-made and cost nowt - I most sincerely hope it
doesn't play you up, but it'd be a bit of a miracle if it didn't at some
stage and, quite possibly, the only valve amp on the planet that didn't
develop a bit of character! ;-)

So what if it does? You're trained in electronics and can wield a soldering
iron - so, not a problem!

Read this (all of it).....

..... and see some geezer got a reet dodgy sample. He fixed it and now he's
got a 'refinished' (see much earlier in the thread) amp for a fraction of
the price of a 'posh' one and he's very pleased with it! Cheaper even than a
kit amp - actually *half* the price of a kit amp....!!

(Don't miss this link:

...... very wankworthy pic of your amp and useful contacts, should you need
them.)


Keep an eye on yer plates for a while and tip it over and have a look at the
innards for signs of stress (burning) after a couple of days. (Check the
voltages, why don'tcha?) And for gawd's sake don't rush out and buy silly
expensive NOS glass for it until you've developed a mutual understanding
with it!! :-)

Let us know how it shakes down - there's been a lot said here (I gave up
reading it all a couple of days ago), much of based on guesswork and hearsay
and I would like a straightford account of one these, er, Ch*** amps from
someone with first-hand experience. (And no axe to grind!)


I'll comment on the sound versus the Cyrus II later.


Hmm, I think I already know what you're going to say.....

Yeah, I found that company yesterday evening.

Here's another pic of this amp in my home, with a CD atop it for scale.

(As I said, I'd assumed it was quite a bit smaller than it really is!)

http://www.fleetie.demon.co.uk/images/yaqin_ss.jpg

It's a bit hard to photograph well and still get the glow and the hardest
thing is to capture the little "bargraph" valves well. They're the ones at
the front, extreme left and right, glowing green.

It warms the place up a bit though, and right now, in summer, that's not
such a good thing!

Anyone else here have this amp?

Incidentally, I dunno what most of the valves ARE!

I'd like some spare ones!

The o/p valves do not look like any KT88s I've ever seen pics of.
They're actually a much nice shape IMO. Normal KT88s are too
short and stubby, IMO. I like these, but dunno if they're KT88s;
does anyone here know whether they could be? Or if not, then some
equivalent valve in a nicer envelope?

Also I dunno what the medium-size values just in front of the
o/p valves are.

I guess they're driving the o/p valves.

The instruction book is ****ing useless and there's nothing in
there; certainly not a list of valve numbers used.
What little there is is in Chinese.

Please see my www.pcabx.com web site for a wide selection of tools for doing
blind listening tests all by yourself, and examples of their use.

Very Interesting! Thanks for that. I'll read it through in more detail later.
The ten tests for listening are pretty much what I do myself and have done for
years, and are very sensible. andy

They should have numbers written on them if they are new. If you tell us we can
give you some recommendations for tube rolling. Andy
