yes, base not pounding, but feels very tight and accurate.
it has a very live and musical feel... (you actually feels like you are there !!)

one more thing... I don't really believe in spending a lot in cables...
but I was introduced to transformers as cables some time ago...
in terms of hi fi... (which usually things costs more than an arm and a leg)
these transformers are very reasonably priced, and give you a noticeable difference !!!

if you have not tried them, you should.

the small ones are about US$100-150 a pair,
the big ones are about US$300 a pair.

then some copper / silver wires, connectors, and bam, you get yourself a connector which is MUCH better than average wires. I show everyone and their reaction is wow... its much clear than before !!
(well, my other wires are not really expensive, but they are those China made 99.9999% pure copper wires)

Very interesting pictures and you are using Leatherman as well. Can you advise what these transform good for and any specification?  I believe this is a very good idea!

回應 TOWINGWING #24 的帖子

yes, I'm a tool freak... I love tools... been using swiss army knife for yrs...
until I tried leatherman wave... this one leave the swiss army knife in the dust, and I never looked back.

ok, back to the UTCs.
they do transformers.  and I believe these are old stocks only also.... nowadays, they don't make things this good anymore...
UTC makes a lot of different types, but for our purposes, only 3 models suits us:
UTC a-20  (small ones...)
something like this...
http://www.ebay.com/itm/2-pcs-UT ... hash=item3cd2854c80

the biggest one is
UTC LS-33

I forgot what the model for middle one is...
they are packed away now... I think both LS-30 and LS-30X will do also.
but I don't guarantee...

utc a-20 is available on ebay a lot...
but if you buy, might as well buy the big one...
also wait for ebay.... they come up once in a while...

then you solder 4 leads, and connect them to the normal RCA connector.
(like my pic)
and use this thing as a normal connector wire (RCA audio cable between cd player and pre amp).
try it and you'll hear the difference right away.

its like you're looking out the window before thru a screen...
and when you use this instead of ur normal cable, you take away the screen and you're now looking out clear and sharp !! its crazy. I don't believe it until I hear it myself.
Then my friends and I were bidding on ebay like a bunch of wild animals for a couple months... lol...

the small ones are one step up from normal cables, and the big one is another step up from the small one.
I got a small one for fun... (and made a nice case to mount it...)

as to exactly which leads, I'll need to look back into the spec, but if you get one, I'll tell you, no problem.
like usual, just need to dig it back somewhere in my computer... lol....

回應 TOWINGWING #28 的帖子

Yes, I think so.  Check the ebay link I provided on my last msg. it has pics.
You can see exactly how it looks like...
or my previous pics too which I wired them...

hkkyiu

回應 TOWINGWING #28 的帖子

ooh... I forgot... you should ask for pics if you're buying online...
cos all of these are used... you want to get a pair that is matching, and they look decent and clean...
some of the old ones are pretty worn.

also, HK$1500 is kind of expensive.

http://www.ebay.com/itm/2-pcs-UT ... d%3D261229988992%26

this ebay auction is from HK, and only asking US$160 = HK$1250.

if you are buying at HK$1500, make sure they are nice and clean matching pair.
well, look at my pic before with the small, medium, large pic...
and check out my small one...  it is in avg shape.

that way, if you buy and somehow you don't like, you can still sell it out without losing too much $$.

Thanks for the information and will keep an eye on this item.  I just wonder these transformer were used in Tube Output only...How can you connect them by pre-amp to power amp (RCA to RCA)? May be it just my misunderstanding!!

hkkyiu

回應 TOWINGWING #32 的帖子

hmm.... let me see how to explain...
you need 2 transformers. one for left, and one for right.

each transformer, you solder 4 leads total (2 pairs).  each pair, you connect to an RCA connector.
So, each transformer becomes a wire... (like my pic above).

so one transformer replace one RCA cable. but we have left and right... (red and white).
So, you need 2 transformers.

you can use it to connect between cd player and preamp, or between preamp and power amp.
My current setup don't have preamp (Wadia has volume control),  so I only need 1 pair.
But I got 4. So later if I add preamp, I still have enough.

these are definitely newer versions.
they have a different woofer than mine.
you bought it for HK$ 4k ? NICE !!

I bought mines at US$1200-1600.
your newer version might not get as much $$, but I think it will at least sell for US$1200.
(might be higher, depending on the speaker condition, wood condition, what kind of wood, serial number,... or original box, booklet, receipt.... etc)

look at ebay...
http://www.ebay.com/itm/vintage- ... hash=item3cd2894a3a
US$4k+ !!!
http://www.ebay.com/itm/Rogers-L ... hash=item3cd2b783f4
US$2700
http://www.ebay.com/itm/pair-Vin ... hash=item3382c116d6
US$2300

http://www.ebay.com/itm/Classic- ... hash=item1c33c3dfec
this one currently at $1600, another day....

Ok, look at this last ebay auction. check the pics...
if you look at the woofer, that circle edge... the color is dull, its like matt color...
that's the old woofer...

your woofer, the edge circle, the material is different... its shiny...

Hi Ching

I have one pair as well and it looks the same as yours.  I bought it brand new in Mongkok over 10 years ago for HK$6,300.00.  I believe it should be around HK$8,000.00.

It should sound better than the re-issue one.  All drivers and crossovers were made in UK by KEF. and the re-issue one....I do not know.

If you bring them into China. You could ask for Yen8,000.00 as well (MADE IN UK).

Hi Ching

It doesn't sound good driven by my 200w class A amp but when I changed to 22W tube amps it was astonishing.
You can never believe that such a small box with the price of 4k can produce sounds like that!
I believe it cost only 4-5k decades ago before 停產. Correct me if I'm wrong.

you need to push 35a with tube amp.  try a tube amp with EL34, it will sound sweet and lovely !!
