hello friend,
we haven't fully recovered(rather not fully consumed the full dose) with this poison, now got better poison?
shall we ditched this poison? heck, NO!

Whoa xtorm! Thats a 'major' surgery!
Whats the outcome?
BTW, do you know it's 4am when you posted that?

I was 'on call' and the 'patient' is under close observation, 18 hours have lapsed.
The good news is the 'patient' has shown an improvement, the 'operation' was a success
Now to prescribe a good 'medication'
Have to check out another 'patient' now

BTW, do you know it's 5.36am when you posted that?

Patient 1 was in surgery,
removed the suspected 'organ' and transplanted a similar organ from the donor (patient 2)

Attached are the sequence of the 'procedures'

Now Patient 2 is under close observation to see if this transplant will rejuvenate and make Patient 2 perform better

The doctor will report on Patient 2 progress soon.

Surgeon General Department Warning: May Induced UDMS(Uncontrolled DIY Mod Syndrome)
Observation Report
5 hours burn in has lapsed, for a total of 7.
These are the findings:
Caution: References were made to original report, hence,

1. Feels like a thin 'veal' was removed from the soundstage.(probably due to the added burn in hours)
2. Cleaner, tighter, well controlled response esp. vocals and highs (added caps)
3. An impressive separations of instruments. (similar to ori)
4. Bass is a little bit defined, just a touch. A little too 'bland' for my taste. (almost no change)

Conclusions:
1. With 2uF NP there's just a touch of sonic differences from stock configuration.
2. Removal of the polarized 1uF cap is recommended.
3. Patient 2 is now in better shape and performance, will kick ass soon!
4. Will induce Patient 1 to carryout transformation as per Patient 2 or better!

Details and informations are true at time of writing.

End of Report.

I have been reading (as usual) and this is what I found:

http://myweb.tiscali.co.uk/nuukspot/decdun/t_amps.html

Very important extract:

"...In order of preference, I preferred the SMPS best, the battery, the regulated supply and then the wallwart. The SMPS was clearly the best sounding supply and once I had tried it, I had no desire to use the other supplies!

Looks like I will be taking that direction..

.. more reading stuffs..

"Note : USE TWO OF THESE AMPS IN A BALANCED CONFIGURATION FOR EXTRA HEADROOM AND DYNAMIC POWER.

TO DO THIS YOU ONLY NEED :
- 1 RCA FEMALE INPUT PLUG THAT GOES TO TWO RCA OUTPUTS. YOU WILL OF COURSE NEED 2 OF THESE.
- FOR THE SPEAKER OUT JUST CONNECT UP THE 2 + OUTPUT TERMINALS TOGETHER WITH SEPARATE SHORT JUMPER WIRES AND THE CONNECT THESE TO YOUR POSITIVE SPEAKER CABLE. THE NEGATIVE WIRE ONLY HAS TO CONNECT TO EITHER NEGATIVE OUTPUT TERMINAL. EASY AND BOY IS IT WORTH IT."

Anybody wanna give this a shot?

ongbs,
I had some difficulties too trying to make out what he was trying to say but,
yes, as you said it, one board driving one set of speakers!
Therefore, you need two boards to drive your stereo speakers!

I'd rather go the bi-amp way

xtorm,
risky? hmm maybe. but personally I wont do it

Yes.. its all about high quality caps and that yellow thing although acceptable, can be better!

That 10uF that I use does reduce the 'brightness' as compared to using just 2uF.

I have this wild idea about bi-amping; the amp feeding the tweeter will have 2uF input caps,while the amp driving the woofers will have a 10uF input caps!

Since I already have that configuration, I will do that!!!

I'd say 4.7uF would be midway between my 10uF and 2uF experimentation. 6uF would be perfect!
4.7uF would be a lil bit 'more' bass

Yes,quality is everything, that Panasonic caps would be just great!
Where did you acquire it?

1uF would do the trick nicely.. if you're a detail freak..
I thought of going higher than 10uF however, since the EPCOS 10uF NP caps is performing so well.. I shall not progress further on that!

Time to fire up the SMPS!

ongbs,
As long as you're happy with it, stay with it !
Yes.. big caps you have there! I have to make a note of that! I have NOT gone into replacement of that existing caps yet.
Saw the [M] logo. Panasonic? No idea. Have never used them before. Expensive?

Whoa.. you even mod your speakers! Way to go!

You got a spare AVR casing! Good for you!
With that huge power switch, its gonna be NICE!

Whoa.. kinda steep but, truly worth it when you're happy! Why bother if it's a Panasonic or not, right?

BTW,
I am at this point of time running an SMPS rated at 12VDC 2.5A feeding my 'lil marvel...
As I earlier pasted from a website, I concur that SMPS is better than linear PSU!
The whole spectrum of sound are now have more 'body'.. it's truly amazing! I can't believe it myself, but at 1.00 am in the morning,
I can hear every little bits of music- the lows, highs, mids, even more.. I only fear now is that, I am NOT going to bed as planned.. it's already monday morning! After the Diana Krall CD I must hit the sack... i must

6W at 0.1% THD!
Yes! Playing using my TDL's RTL3

A puny 'lil thing driving a huge monster!

Just completed Diana Krall's Boulevard of Broken Dreams.
Although the SMPS drove the TA2024 well, it lost to linear PSU in terms of resolution..
Meaning, the differences between vocals, instruments etc is more distinct with linear PSU than SMPS..
I bet using toroids would push the fidelity further.. damn!

Take note I have not replace any other capacitor onboard other than the input caps.
Have to check out how the DIN55 batery will perform. Definitely not tonite! (morning rather!)
Heyy you're sleeping late!

For RM30 its 'cheap'.. but it is not kinda huge housing for a small little thing?
OH, you gonna house the PSU too right? I guess it should be okay..

On my side, after the listening session, I have to conclude that I love the T-Amp sounds with a linear PSU.
It has to be as good as my Bench PSU or better. I would NOT settle for any less..

Actually the housing that I have is even bigger! It's supposed to housea pre-amp and it's PSU, a power amp and it's PSU and mains RFI board.
That project was on hold.. looks like I will use it for the T-Amp.. a definite overkill!

Yup. This is what he meant!

I bought a (high quality) pre-amp kit a while back for another project.
I thought of using it with the T-Amp.
I won't use a simple pot for it
At least use a simple buffered pre-amp for the T-Amp...
omg.. too much 'amp'ing here..

In a quest to find out how far the T-Amp can and will go, I will!
Bear in mind, I am using my reference pre-amp (a Yamaha) along this while.
It would be interesting to find out how far you can stretch the budget with electronic kits.
I am all for 'bang per buck' setups
Anyway, it won't be happening until the weekends.. need to rebuild the power supply for the kit pre-amp as I am using it for 'something' else..

edit..
I just remembered why I did not use the pre-amp on my other amp, it was insanely accurate and sensitive, revealing almost, if not all the 'flaws' from the source.. amplified everything, noise included!

So far, the Amp-1 or Patient 1 has clocked 11 hours, while Amp-2 or Patient 2 managed 14 hours.
At this juncture Amp-2 is the sweet performer due to the 10uF input caps. I will keep the current configuration for my bi-amping setup which I am planning this week, among other things like the above..

It would be fantastic if I could get my hands on these casings..
