mysghooi,
This Class D amp is made for sub woofer amplification, pro amp and mixer amp applications.
I have NO idea how it would sound like. tongue.gif
That is why if it is 'affordable' I might just get one to sample a Class D amplifier not based on Tripath chip. biggrin.gif
The company sell SMPS with all the amp boards.

QUOTE(mysghooi @ Aug 20 2008, 09:02 PM)
Wah this thing seen with a lot of juice to drive the speaker don't know how is this will sound.
If the price is good I might get it from you jazzy939.


Added on August 20, 2008, 9:04 pmHi what transformer to you recommend for this T-amp? and how do it sound?

Y.C.,
As I earlier mentioned, at RM55 for the basic board, it's Best Bang per Buck Amp! thumbup.gif
The TA2020 might be better, in terms of slightly higher power. I have NOT heard it, so I cant pass any judgement on it. tongue.gif
My system is now singing, sounding the best I have heard for the last 20 years I am in HiFi..
As far as I am concerned, the TA2024 still RULEZ! thumbup.gif


QUOTE(Y.C. @ Aug 21 2008, 12:56 AM)
Charlize T-amp is with the TA-2020 chip with max output of 2 x 10W into 8ohm and 2 x 20W into 4ohm.

In a 2005 TNT shootout where 4 different T-amps were compared, the reviewer preferred Charlize over others. See link: here.

Charlize is a product from diyparadise and available either in finished product at RM1,000 or in kit form at RM350.

And at such prices, I felt Charlize could not be compared to the TA-2024 kit at only RM55.   thumbup.gif

Your guess is right biggrin.gif
It's between 40V-50V,7A @650W.
I'll get the quote for the SMPS too. Waiting for the reply now brows.gif

ongbs,
Instead of 'modding' your crossovers why not go overboard to electronic crossover? <-- poison eh laugh.gif



QUOTE(ongbs @ Aug 21 2008, 09:07 AM)
Well say bro jazzy, i got the same feeling like you, tho i am not into real hifi world smile.gif
I need to mod the crossover of my floor standing(FS) speakers to suit this Tripath amp and my ear....to get the most out of this amp.

I never know that my FS speakers can 'sings' this well....even after 8 yrs long!!!  rclxms.gif

xtorm,
let's see what the quotations will be like. tongue.gif
From a meagre 6 watts jump into a 'light speed' of 200-300 watts, 'few' hundred bucks is STILL worth it! laugh.gif
Don't you think so? NOT that you're gonna play at FULL power, but the extra headroom does helps in the dynamics. Then again, provided the fidelity is as good as the Tripath.. which is going to be our, well, my benchmark now. biggrin.gif
WE'll never know until we sampled one, right?

QUOTE(xtorm @ Aug 21 2008, 09:26 AM)
jazzy, wah i think tht amp not gona be cheap edi, at least few hundred i think...

bro ongbs,
thank you for the vote of confidence! thumbup.gif
hopefully will receive a reply by this afternoon.

Y.C.,
I whole heartedly agree with your statement! The bolded one! biggrin.gif
My pre T-Amp setup is based on a 90W RMS/Channel, Class AA amplification. Imagine how sceptical I was on a tiny Class D 6 watter! laugh.gif
The T-Amp phenomena did not change the whole hifi industry overnight and make other classes of amplication obsolete, it just give a new insights with regards to the performance of class D or in the case of Tripath, Class T.

Personally, I am here for the music! biggrin.gif
We want the 'best' for minimum RM, always on the look out for best value for money stuffs and it so happened TA2024 came calling in tongue.gif

At the end of the day, what matter most is (at least to me!), if it makes us enjoy the music like we want to.. so be it! It doesn't matter if it's a RM55 6Watts amp.. laugh.gif

QUOTE(Y.C. @ Aug 21 2008, 03:49 PM)
jazzy,

As much as I suspect that I will prefer the Charlize (TA-2020)'s sound over the RM55 TA-2024 kit amp that I ordered from xtorm with its slight more power and purported finesse if I were to perform direct comparison between the two, I wholeheartedly AGREE with you that the TA-2024 kit T-amp is the Best Bang per Buck Amp; and if I actually find the 2 x 15W into 4 ohm power of TA-2024 kit amp is adequate to drive my Q-Acoustics 1010 loudspeakers at moderate and not head banging level, I will stick with the TA-2024 kit amp and forget the Charlize kit at RM350.

The TA-2024 kit amp at RM55 is a no brainer, it is almost a sin not to try it out if we happens to be on the look out for an amplifier.  thumbup.gif

xtorm,
the TA2024 is my first from Tripath.
I had played around with alot of DIY amps.. namely discretes.. about to start on GainClone but was put on hold because of the 'expensive' toroidal transformer requirements.. then the TA2024 came along.. laugh.gif

I don't think I would want to try out other Tripath chips, unless they're "a sin not to buy" biggrin.gif
But I am curious how would other Class D would sound compared to this TA2024.. hmm.gif

yeah.. you and your input caps! laugh.gif but I do agree with you wink.gif

QUOTE(xtorm @ Aug 21 2008, 04:48 PM)
haha

audionote making good money with small watter tongue.gif

eh bro jazzy u play with ta2022 b4? or was it another t-amp?
bro Y.C...hahhaa thts a pretty good statement, you heard charlize before, once you have done yours give us your feed back, i think in the original form ta2024 is no match to charlize, those input cap must be change! icon_rolleyes.gif

gabanyayaya,
The anticipated reply from that Class D amp supplier did not arrived. sad.gif
My GainClone project still KIV.. am NOT giving up hope yet.
I don't really want to pit the T-Amp with the GC. Eventhough they are chip amp but they are from different breed altogether, unless the GC is also a Class D, you know what I mean? laugh.gif I am not throwing out D'Bom either! brows.gif



QUOTE(gabanyayaya @ Aug 21 2008, 08:03 PM)
jazzy with a good philosophy....KIC KIC KIC.....RM36 for a 20uF......!!! I'll pass.....I think can get from online slightly cheaper than that thanks.... for what????....hehe another mod.....  smile.gif

jazzy your killing me here....if the Class D that you try to get is around my budget I think I might suspend my Gainclone project here....updates updates....

gabanyayaya,
if you were asked to pick between the T-Amp and GC what would be your choice? Tough one, huh? What about D'Bom thrown in for good measure? laugh.gif

I found out from another thread that the so called supplier that I was communicating with was the designer of the amp himself! tongue.gif
He must be busy, I'll give him some time to respond... no big deal here.. It is just an option. biggrin.gif
I am not into the 300W per channel thing, only curious how would another Class D amp would sound like using Tripath's TA2024 as the reference. brows.gif

I can't really say whats going to happen. All pending to the $$$. Remember, we're looking for value for money stuffs or best bang per buck. It MAY be affordable.. I am worry about additional costs like shipping etc...

QUOTE(gabanyayaya @ Aug 21 2008, 09:32 PM)
D'Bom...sounds familiar.....last time when i'm considering a class d amp from hypex it cost almost the total of my hifi system and i have to leave it for good...now when you mention this amp kit, it really put me in a mood again for another journey...will you able to bring this to a reality jazzy...??? sure ke belum giving up????? bole dapat harga bagus ka??? well i think the supplier will respond la but takes time....2...3 day  more....be patient la uncle

Fair enough! tongue.gif

Expectations can actually change perceptions laugh.gif

HiFi is very personal.. it shouldn't matter what others say right? wink.gif

Yes.. I do not expect the shipping to be that high, after all its a small 'package'..

We'l have to wait and hope for the best...

I'll spin 'The Best Is Yet To Come' in the mean time... still 'burn in' the T-Amp.. whistling.gif

QUOTE(gabanyayaya @ Aug 21 2008, 10:15 PM)
hey jazzy....don't put D'Bom into the lines la....just let it be as it was.....a ref. besides your Technics...can't put it to the same league as others....

between GC and T-amp......hmmmmm my last visit to diyparadise Charlize last AV show...I found that the sounds of Charlize a bit 'backwards' with their full range horns......i don't know why but i wasn't impress. maybe my ear or something else. but I think SQ vary between different T-amp designs. GC...got no idea how does it sounds....... hmm.gif

Like me too.... I'm not after at those heavy monster wattage power lah.....me just like a moderate  40-60W amp. The most important is the dynamics it can produce out of those tiny wattage power to my speaker that counts...

Carefull curiosity will lead you to overkill...hehehe

As for shipping I guess won't cost a fortune ler........once can bulk you save more, besides look at LY bulk section, there's many people willing to help... brows.gif  Lets poison poison here... biggrin.gif

I have read this somewhere and I tend to agree..
playing the T-Amp especially in the office will not get your work done tongue.gif

Again, like any good amp design, a good power supply would help or made (some) difference!, eventhough the Class D amp are not that 'choosy'.. linear or not, SMPD, batteries, anything goes! biggrin.gif

So for a 'normal' no frills 12VDC 3A regulated PSU would costs around RM50-60, inclusive of other minimal hardware requirements.

Is this 'too much' to pay? whistling.gif

QUOTE(gabanyayaya @ Aug 21 2008, 10:49 PM)
Want to try some acoustic sounds...??? just loose that Diana Krall for a while lah.....

Jazzy would it be costly too for other extra part for the class D like PSU, tranny, plug... etc???

Again, this is very subjective! laugh.gif

Heyy, me too! Anyway, I am about to get a quote for this type of casing tomorrow.. wink.gif
What you think? Or you have a particular style in mind, why not share it here? nod.gif


QUOTE(gabanyayaya @ Aug 21 2008, 11:16 PM)
As long as the amp it self doesn't cost such ridiculous amount i guess nahh...but....casing must be good. I like a unique casing....any ideas/lobangs?

This is even worst! = more expensive! tongue.gif
I see lotsa machined aluminium alloy! shakehead.gif

The casing that I like will only require a 'flash chrome' plating and a good fine metal polish.. wink.gif

Wonder why we are the only two 'chatting' here.. hmm.gif

QUOTE(gabanyayaya @ Aug 21 2008, 11:41 PM)
anything shiny and glittering is EXPEN$IVE.....that casing looks very overkill kill kill....

how about this one

I'd say it will 'look' expensive wink.gif It's just a 'flash chrome' plating, followed by fine metal polishing, buffing.

I have this spare PSU casing, if you're on a tight budget, it will suffice. However the PSU will be on a separate similar housing. Certainly would look nice, side by side.. wink.gif

QUOTE(gabanyayaya @ Aug 21 2008, 11:49 PM)
for me it sounds expensive......how much it cost jazzy (agak-agak)? hmm.gif

Dunno ler.. need to find a nice free time for this..
However, have to wait until ALL is done for this T-Amp!
I just found huge(in size) caps that I want to use at the power input section... wink.gif
Will update soon. Need to use that tonite as little improvements can easily be detected at this hours.. brows.gif

10000uF at least, the more the better! biggrin.gif


QUOTE(bsl555 @ Aug 22 2008, 01:25 AM)
That must have come from some PSU. Its not suitable.
What you need is uF that reads 5 figures (or you parallel them altogether) with a few hundred VA transformer (bigger the better).
