Sorry again guys. Absolutely have to be elsewhere that morning onwards till late.
Door gift...nevermind.. I pass.

Understood bsl.. next time round, eh?

Err, even the Sonus Faber door gift would not be able to tempt you to change your mind?

On a more serious note however, we should not be over imposing our invitation although we sincerely would love to have you around in our T-amp session. Perhaps another time as Jazzy has put it.

hope my work at site wont drag me too long, doing some troubler shooting, so hopefully all well.

but no tube pre-amp tho, no time to pick it up in klang

You are the main star of our T-amp T/T session and better be there, else we would re-schedule it just to accomodate you.

It is okay with the tube pre-amp, we would do away with it till our next session to be hosted by Jazzy in due course.

Oh yes, you better be around, xtorm!

My turn next session?

had come across building this tamp with stock configuration except added rectifier on the power input, alps pot, and heatzink for the Tamp chip.. as i accidentally killed a klipsch promedia ultra 2.0 speaker internal amp by mistakely plug in the wrong polarity of the speaker. hence, the klipsch were modified into passive speaker with banana plugs to be driven using this T-amp.

i had mainly using this as my portable setup for roughly a month as currently i spend most of my time in lab. hence this will be perfect for me as the whole amp + speaker setup can easily fit into normal bag. so this will be my portable hifi setup.

Mini Amp + Mini "floor stander" form factor speaker + Portable player (zune) + Short speaker cable.



the 4 banana plug terminal is the most heavy things for the whole amp. all the other component added up still not as heavy as the 4 banana plug terminal. lol.

PcWork,
Good job there! Just by looking at the cables I knew it was you!
You're running a stock T-Amp but with your cables.. wonder how much different if compared to a stock T-Amp with 'normal' cables..
Will you be joining us tomorrow?

i think tomorrow i can't join lah.
i not yet sleep since yesterday..
feel really tired. brain can't think already hence i come and post picture. lol

Nice... I am getting a T amp soon.. and it will be driven by a diy tube pre-amp (I actually had it long time ago). I also have the vintage CORAL 8A-40 full range driver but no enclosure yet..

hi mikoblackcat,
soon as in 'batch 5' ? how soon is that?

Can you give some details of your DIY tube pre-amp..? TQ.

PcWork,
Great pictures and neat handiwork 
How do you like the sound of your T-amp? Share with us?
And as for your speaker cables, their weaving looks like Kimberkable but what are they?

Welcome aboard, Mikoblackcat.
You are collecting your T-amp in a day or two?

Jazzy,
I do not know whether if we were to push our T-amp T/T session to next weekend, would we have more people attending it? So far the only people having confirmed they are coming are Jazzy, Gabanyayaya, March, Xtorm and Y.C., did I missed out anyone?

On my part, the full discrete T-amp is not completed yet with some capacitors in Vishay MKT1822 2.2uF and Panasonic FM 470uF arriving from Farnell next week.

What say all, do we carry on as planned or we postphone our t/t session to the following weekend?

so far. as compared to my NAD 3020A (which i usually use the amp to drive my klipsch for internet radio at home)
the T-amp has lesser bass. and slightly narrower soundstage. but overall. it's superb considering it's size. as NAD were at least 10X the size of this T-amp. and the t-amp is hell portable for me.
and i really appriciate i can have more "hifi" sound in lab. i never miss my headphone at all as i have this set of portable setup.
so currently a lot of my headphone were stored in a cabinet.
and one of the reason the t-amp loose to NAD were that the klipsch is actually quite hard to drive. it is even harder to drive than my Tannoy bookshelve speaker.
and default internet amp supplied 15W for each channel.

the speaker cable is not kimber. it's DIY by myself with some cable imported from canada.

PcWork,
It would be great if you could join us in our t/t session so you could listen to the same amplifier with different configurations and see which you like most.
I have associated myself with many amplifiers in the past and in my opinion, the T-amp is way ahead of NAD amplifiers (no offence intended) but you must replace both its input and power rail capacitors on board. For input caps, I would recommend 2.2uF ones whereas for those on the power rail, 470uF.

You could read about my view of the T-amp here: listening to T-amp and further development

well but i am not sure about other NAD. my NAD3020 had been refurbished. and i seriously think it's no fight between the NAD VS T-amp. the NAD is better in term of dynamic. better sound stage, more fuller sound, and much better control especially in orchestra music. and tonality of the NAD seems much accurate than the T-amp.
both amp were tested using VDH D102.

perhaps on your music, you seems like T-amp more. but i guess in any aspect. i will say that the NAD is more suitable for my personal taste, and the music i heard. however. T-amp is superb as it's portable.
i will do the modification as you mentioned and shall update with you the improvement. but it couldn't be done within this two weeks as i am heck busy. it is glad to know that the t-amp still has room of improvement, i also wish to max out the t-amp performance. with the hope i could has better sound in my lab. =)
thanks a lot for the recommendation.

Y.C.,
I think next week would be more apt, in the sense that more would be able to make it, bsl included hopefully..
My vote for next week? YES!

PcWork,
You certainly do have great attitude.
The views expressed in my blog are solely mine and not meant to be imposed onto others.

Jazzy,
Thank you so much for your understanding.
I wonder how the rest of guys would take to the postphonement of our first t/t session. I was also looking forward to bsl joining us as a nuetral observer and listener, maybe we could succeed in spreading some T-amp poison to him as well.

Thanks but no thanks in me doing up a T-amp in future, primarily because I've no need for anymore amplifiers.
I've already had enough fun with DIY amps in the past. I could always pop by to March05's place to listen if there's any opportunity. About next week, I'm also foreseeing not able to come to your party. Wrong timing and a lingering issue at this point of time I've no choice but address it on weekend. Yes, Amcorp Mall stint may again be dismissed. My apologies.

by the way. it is strongly recommended to add a heat sink at the t-amp chip. i notice that before i add heatsink, the ratio of bass VS mid VS treble sounds slightly different at low volume and high volume. i assume it is caused by the heat of the t-amp chip hence at louder volume. the treble seems to be fatigue to ear, and lesser bass at louder volume. but it is solved with just added a heatsink.
worth to try though. else. it might as well pro-long the life of the amp.
definately worth trying.

For me, I think TT postponed to next weekend is a bit better. But if it is to be tomorrow, I will still be happy to come! Don't know why, suddenly this week ending so busy.......
