ongbs,
why don't you use all balck donuts? tongue.gif

actually you can overlap the coils..

So your input caps is 2.53uF total?

I put in a ELNA 2.2uF on Board 1.. obviously better that the yellow stock caps..  the sound is more lively! biggrin.gif

Here's the pix...

So ditch the green ones and totally use all blacks! tongue.gif

Not much DIY on the T-Amp today.
I was rebuilding the PSU for my external DAC.
Then a friend drop by to mod his external DAC also.Fix a new coax RCA socket of his Marantz CDP.
And was listening to some great CDs using his front end and my T-Amp..
What a great Sunday afternoon! thumbup.gif

Further update: My T-amp has clocked approximately 20 hours at 22.00 on Sunday, still a long way to go before it is fully run-in though. It now sings much better and sounds more beautiful than yesterday and by right I should let it alone to continue to sing. However, the curiosity to tweak got the better of me and armed with my soldering iron, I removed the 4 capacitors on board. I replaced the input caps with a pair of Vishay 2.2uF 63V polypropylene capacitors and as for PSU caps, with a pair of Panasonic FM series 1000uF 16V electrolytics.

How did the changes in caps affect the sound of my T-amp? I will come back to this shortly after describing the pair of bookshelf speakers I have paired with my T-amp. Q-Acoustics 1010, to me, have almost perfect highs and midrange which are seamlessly integrated and at its selling price, second to none. Their setback though, is they do not have ‘any’ bass to speak of and they do not throw a big soundstage like many other loudspeakers. Being a midrange guy, I could easily accept their shortcomings and live with them.

I had initially placed the pair of loudspeakers sitting directly on the wooden flooring in my bedroom. After a couple of hours of listening to music through them on Saturday afternoon, my ears could no longer tolerate the hardness and ‘overpowering’ bass I was getting from them. I had also mentioned with normal recordings, bass definition of T-amp is a little vague.

After the capacitors change, I only hear subtle differences and not those between day and night. First, the hardness and ‘overpowering’ bass I was hearing through the stocked caps are now gone. Bass is now softer with bass lines more well defined (less of the mini-compo effect in bass I thought I was hearing at times earlier). I thought this is how my Q-Acoustics 1010 should actually sound.

I also thought the highs now sounded more refined and slightly airier and midrange especially in vocals sounded slightly less forceful than before. Is it better? Hmmm, ……

hehe, same as you, got a friend came over to test T-amp at my place yesterday...
I purposely cover the amp with paper, the bare board without casing sit on the floor(patient 2).

After 15 min enjoying music then I opened up the paper, he..."WOW! The amp so small!" laugh.gif

I just bought 2pcs of twin-binding terminal for speaker box , wanna mod my FS for bi-amp too brows.gif

Previously, I had asked whether the midrange and highs of my T-amp are really better after the caps change by me? I have listened to several more CDs since then and my answer now is an undisputed YES. Vocals sound airier, livelier and less forceful (hardness in midrange greatly reduced). I would think a CD player proper would be required in my setup to totally remove any hardness remaining. The overall sound now is a touch lighter compared to before.

My latest CD used to test vocals and resolving-ability of amplifiers is Il Divo’s first album (Sony BMG 828766765427) where ‘Unbreak My Heart’ is the first track therein. This is a non-audiophile CD and I only owned a local-pressed copy. With most amplifiers, this CD would sound rather noisy as Il Divo is a group comprising of 4 male soprano singers brought together by Simon Cowell (yes, the outspoken judge of American Idol). After the caps change in my T-amp, Il Divo sounded very very close to what I am hearing through my Simaudio Moon i-3 integrated amp and this is really unbelievable as resolving ability of my T-amp now has surpassed that of Exposure 2010S integrated amp, an amplifier being retailed at RM4,300 and a Stereophile Class A component.

In concluding my series of review (read also earlier Posts 1011, 1017 and 1046), I would say even in its stocked form, the T-amp kit at RM55 (throw in another RM100 or so for some decent RCA plugs, speaker binding posts, wires, a volume potentiometer and casing) is a great sounding amp and giant killer. If any of us are on the lookout for an amplifier, it would be almost a sin not to explore and consider picking up the T-amp. Without comparison, many of us would be pleasantly surprised, charmed and could happily live happily with its sonic qualities.

Its performance could be better improved by caps change, especially the input capacitors. There would be no clear answer as to which brand and model of caps is the best as each of us actually listen to and seek different things in audio. No doubt very expensive ‘boutique caps’ would bring about greater improvements to the T-amp's sound, they are beyond my consideration as I myself seek for the greater bang for ‘RM’ spent.


Xtorm,
You had asked about the sound staging capability of the T-amp. Currently, I positioned my loudspeakers 3 feet apart from one another, each sitting on a stack of magazines and books. And within this setup, yes, I hear the T-amp image well, vocals well fleshed out (as opposed to cardboardy sound) with decent sound staging within the setup. I would think it would not be any lesser than most other amplifiers. I will comment again on this area much later after I have fitted my T-amp into its casing proper and after listening to it within the confines of my main listening system.

Yes, I've concluded my preliminary review on the T-amp, will add anything I've missed out from time to time. tongue.gif
