Looks like it is!

So you're using the same SMPS that I am using, right? Excellent piece of hardware with 4.2A ready on tap!
Good work Lai!

I agree, as if the SMPS and the T-Amp was meant for each other!

Like the pix bro.. any close up shots?

Anyway,
I found a super duper CD mechanism that is now a CD transport feeding my pre-amp buffer, T-Amp via a DAC. So far, results has been encouraging. Will reveal more pending final audition and conclusion.
Super duper here means it's 'dirt cheap' and GOOD!

Mean Well 12VDC 4.2A. RM55
I believe Y.C is using it too besides mysghooi and myself.

Get it from the shop next to NIXIE, Jalan Landak off Jalan Pasar KL. Sorry, can never remember the shop name!

There is a GROUND connection at the SMPS. It's there for a purpose..
The mains ground wire is connected to this point.
Also the SMPS mounting is isolated from the metal casing. SAFETY FIRST!

Y.C.,
I am with you. The Class D(Class T incase of Tripath) amplification is of high efficiency design(90%, 10W @ 8 ohm)), infact 1A is already aplenty. And our 50W SMPS is way overboard!
But I have a reason for that. The same SMPS will also powers my pre-amp and also for bi-amping.

Yes, surely he was and thank you for your timely reminders and pointers bsl!

Y.C.,
you may have a point there, and the T-Amp will more likely to go into clipping and drain more power hence the emphasis on high efficiency speakers

I do have a 'spare' car battery around somewhere.. may try it out and see(hear) if there would any difference in the sonics.. my gut feeling say it would be most probably in the low band/frequencies region... depend on your equipments also. I would say the choice on the type of PS is more on personal preferences and conveniences...

I have two more types of caps to try out.. so it's a good excuse to open up the casing and at the same time try out the car battery..
Will revert if I have the chance to do it, maybe tonite..

bro March,
That is a great idea!
Yes, on the next TT Session, it would be interesting to know as such. We'll call it Battle Of The Lead Acids!
Anyway, I can barely remember something on a certain types(brand name) of lead acid batteries that sounded better than some other brands.. no not the batt sounded better, the equipment that is! (pagi2 punya joke) I think its a certain type/brand of SLAs that they were using for the T-Amp.. So, would there be differences between SLAs and CAR BATT?

I am keen also to find out as my current buffer preamp is running off a 9V batt. It sounded 'clean' and 'crisp' and I am wondering,'what if the T-Amp is also batt powered?"
Bro March, you should compare the passive pre and this buffer pre.

So, next best questions are, TT Session, when and where?

wui,
That was reported by Y.C. some postings back. On my side the 'thumping' or inrush current sounds did subsides somewhat but I do not know if it has disappeared altogether as I am using a speaker relay/delay board. There were also some 'noises', mild ones from Junior's T-Amp but I don't think there are any now..
Have no idea how to help you/your board...

p/s
There is some 'noises' from Junior's T-Amp but only on the right channel..

I was also tempted to get the ALPS for my buffer pre-amp but after considering the price against the total cost of the pre-amp.. I decided not to, as I am terribly happy with the current SQ.
Also I am trying to keep within the 'best bang per buck' category..

No doubt, there would be sonic differences with the ALPS, I just do not want to risk upsetting the sonic balance that I am having right now!

xtorm,
the need for V2 is paramount!

A suggestion,
in the FAQ, can we list all the input caps used by the members? Including it's influence to the sound? This should help the newbies. Also keeping the V2 of the thread kinda 'clean'... we do not want to repeat ourselves all over again..

Monkey King,
Good to know that!
So, whats your next step/mod?

To ALPs or NOT to ALPs , that is the question!

The T-Amp works well with a passive 100K. My buffer pre-amp is also a 100K pot. The range of travel is well balanced in both case, I would not go any lower.. just my 2 sen.

If you're using a stepped attenuator or a pot as a passive amp..

cyl1000,
Some of the JP stuffs you can never know when it's gonna failed on you. Due to the 'cheapness' I normally bought extra 1-2 depending on the parts. For spare just in case! So it would be worthwhile then to fork out acquiring the real stuffs eventhough the price is 10X JP prices.. peace of mind for the next 10 years(?)..

Bro, the super duper casing was bought by a friend in Bangkok and hand carried back to KL. Price? RM300. Don't ask me where he got it, as I have forgotten the place/website. I will try to find out though..

I use a 'normal' 30A electrical cable for speaker output except the input uses shielded stereo cable.

gabanyayaya,
that binding posts probably not the same 'elcheapo' ones that you bought! This one very sturdy! Mine also cheapo but better...

gabanyayaya,
I need a few pairs of those too for up n coming projects. Will keep a pair or two for you.. Unless you want the 'gold' plated one like Y.C.'s which you know where to get, I am getting mine from this particular shop.. as the others are.. not good enough for me eventhough the price is similar, the quality is not. Such is JP's products... We all know that by now, right?

I will only handover that buffer when I have a better replacement! Which is coming up next!
