回覆 (192): Chopin Now and Then
Here is an extract of the Kissin playing the Chopin No.1 when he was merely 12 years old.

回覆 (191): Chopin
Very sick of all the bloody hell that is going on in Hong Kong right now. Nothing changed - Incapable vs. the day dreamer.  
 
This one below actually gets better. Kissin first recorded the Chopin Piano Concerto No1 when he was a child at the age of 12 and that made him one of the world most famous pianist for the rest of his life.  
 
Here this video was recorded a few years ago when at the age of 43, oh......so much more accurate and expressive when compare to nearly all the different versions I have experienced. A must for classical fans!  
 
Something never changed. Something always improved. Choice is in our hands la!  
 
 
Enjoy!

回覆 (184): Meridian M100
I can see a red light near the foot of the speaker.  
Is it driven actively by amplifier built-in?  
 
------------------------------------------  
 
Yes, the M100 is active consisting of three separate amps for the treble, mid and bass drivers. Two transformer together with all the electronics are located in the wooden foot/stand of the speaker.  
 
User can choose to have the amps fully on all time or on standby until the amps receive a signal which auto activate the amps and switch back to standby after 10 minutes of no signal. Kind of a luxury feature in the late 80s, right?

Very heavy indeed! During restoration, I have discovered that the whole cabinet is made in not MDF but birch ply wood. Jolly!  
 
The KEF B110 line up produced a very warm and distinctive vocal that is surprisingly pleasant and considering it was first introduced in the early 70's, I am really starting to feel curious and questioning about the advantages we have gained in the so called modern technical development in recent speaker design.  
 
Just look at horn speaker and its related tech, kind of stalled since early 70's, right?  
 
Personally, I can live wonderfully comfortable with 70s to 90s Hi Fi components lor!  
 
The connection between the amp and the main speaker unit is via detachable sockets which is located at the rear with easy access. Perhaps, at some points, I could build an external crossover to mate with my home brew valve amps. Ha ha ha!  
 
By the way, anyone with 70s to 80 made speakers, please check the condition of treble unit and find out if it may require ferrofluid refill. May have dried up by now!

Much of the hard work was on repairing the veneer. Sand, dye and polish which took me more than two weeks of intense labour.  
 
So, how do they sound? you may ask!  
 
How about a beef up LS3/5A with thundering bass. The stereo imaging is exceptional. The treble is very smooth. Best mate with jazz and classical. These speakers are not for big Rock fan or heavy metal.

Here is the rear view of the speakers.  
 
Features:  
1. Six KEF B110 SP1057 white bellies per speaker. The SP1057 is almost identical to the famous LS3/5A SP1003 except it has higher power handling.  
 
2. Three separate amps for treble, mid and bass. Total 2 transformers in each speaker.  
 
3. Bass down to 30Hz with the help form a B139 at the rear.  
 
The Meridian M100 was the last of Meridian active analog speakers that ease production in the early 90s. Total three amps inside each speaker, 140W for the bass, 70W for the mid and 70W for the treble.

After almost 30 years of waiting and day dreaming. The most desirable speakers for me finally here at my den singing. Many thanks to Cadiver for the shipping arrangement. A bottle on me when we next meet!  
 
The Meridian arrived in rather poor shapes and restoration a must lor!  
1. One of the KEF T33 treble unit was open circuit. A quick search from Bay watch got me an used one but came with a smaller magnet ( there are at least four variations of T33 throughout the years of production in the 80s). Fortunately, all T33 variations share the same voice coil and only differ in the magnets. Here I replace the voice coil of the broken T33 in my Meridian and fill with Ferrofliud.  
 
2. Cold joins in both RCA sockets, a quick soldering job!  
 
3. One small cap in the power amp got shaken off over the journey. Another quick soldering job. Easy!  
 
4. The Meridians came for the US and were connected in 110V. Series solder the transformer primaries, simple task la for bobui!  
 
5. All caps and other components were in fine working orders after measuring with a scope and signal-gen. The last owner basically have these speakers sitting idle for more than 10 years!

回覆 (177): Top Four!
Price of the Top French wines has dropped quite significantly for the last year or two, thanks to the Mainlands anti-corruption campaign. But really good ones, especially those exceptional aged vintage, they could still cause a fortune.  
 
Of course, no matter how $$$$ and how GOOD the bottle could be, it's just only a wine. Pls don't over fantasize  
 
Asahi is not bad at all, I can live with it.

When I first drink Palmer, it was less than $50USD a bottle, current vintage $250USD for current production. Those same $50/bottle may be around $800~1100USD today if my guess is good. That same time Mouton was about $85/bottle, today, 2013, Mouton is around $350. Some maths just don't add up right to me. I stay with St. Emillion for French fix. I just heard there are more vineyard in Napa now own by Chinese, not only mainland Chinese but also HKG Chinese. I think in 10 years napa wine market landscape will also change. By then I might just have no choice but drink Asahi only ...

Mouton is not in the same league, even LLC & Pichon lalande are better.  
 
Aroma of the classified growths from Margaux can be addictive, so they never come cheap. Similar situation for the ones from Pomerol, not to mention their small production, thus a limited supply.

The gathering was an invitation from my brother in law. Bobui couldn't be bothered with any of these top dollar wine lor!  
 
Well, the truth is i am really not that critical about wine at all. My sense of tasting is relatively worst than my hearing lor! Ha Ha!  
 
I rather spend it on good recordings and bike stuff lor! Nevertheless, the Mouton was miles apart from the Palmer lor! Even an under age teen gal can nose the aroma from a distant lor!

Some of the 417A ring badly from my 40+ collections. The WE measured the worst of all and sound not as open and lifelike than others. Funny enough, its the most expensive. Raytheon sound the best and is easily the lowest in price. GEC, Ampeg, ITT (probably a GEC rebrand) have also made them under 5842 code.  
 
There is also a Tele and Siemens EC8010 having very similar spec as the 417A.  
 
I had the Marantz 7T switched on for over 12 hours and then put on a "Kind of Blue" side A before off to work this morning. Not bad, not bad for the dollar. Surely not as "lifelike" as a good valve phono but sound not dull or shut in as what some SS phono amps could be. Given the flexibility to play various mono recordings. I do say is a bargain!

Michael Elliott, the original designer of Counterpoint..........One of the options was to use WE417A in place of the 6922s, but it would need twice as many WE417A, as it was a single triode.  
 
---------------------------------------------------------  
 
417A, very good choice for phono first stage la.  
 
The 417A transconductance (gm) is 24,000 micromos which gives a noise resistance of 104 ohms. This is comparable to even some Mosfets that are only slightly better and they tend to have other non-broadband noise sources, distinct from valves.  
 
The 417A also has a low plate resistance of 1.8k ohms and it can handle 24mA. Even at 100v, a 417A gives a dynamic range more than an order of magnitude greater than an equivalent semiconductor and low noise transistor likely to die when such voltage applied.  
 
In comparison, the E88CC has a gm of 12,500 mircomos and a plate resistance of 2.4k ohms

Clever move, 417 is better for this application. Things left are at what cost and how much improvement?

A few years ago, Michael Elliott, the original designer of Counterpoint, offered a service to convert the Counterpoint SA5 preamp into a pure phono stage. One of the options was to use WE417A in place of the 6922s, but it would need twice as many WE417A, as it was a single triode.

A Marantz 7T on the test bench. Both Sine and Square waves looking normal wor! Ready to put on Chopin or Miles for an actual road test.  
 
It has various cut off frequency settings for mono LPs. A luxury addition for a small amount to pay for!

May be, we both wrong, Kong! That tiny little tube next to the GM100 could well not be a 6922. We just cant be sure that it might be a EL34 type of output tube we are looking at! You know what I mean!
