I want to use either one of these amps with Denon D2000


Don't have mini3, but I can tell you that T4 is about on par with a very well built cmoy with a good opamp (i am thinking of a cmoyBB with AD8066 here). However, you assumed wrongly - T3 / T3D come a year after T4, so they actually sound better than T4.


Agreed, the T3 is more open and transparent sounding than the T4, while the T4 sounds a little darker and less detailed.  (haven't heard a T3D, but Jamato8 thinks the T3D is worse than the T3)

I can't recall what is was that Jamato8 thought made the T3D worse than the T3.

i was considering buying an amp a while ago and had a listen to both t3 and t3d.. i don't remember what it was, but i preferred the t3. at the end i didn't buy either though.

To my ear the T3D has a bit of grain or dryness on the upper frequencies. I have heard this with other digital controls and attribute the edge to the control as the T3D and the T3 are otherwise the same. Two other well known portable amps with a digital control have the same edge to the upper frequencies I hear on the T3D.

Are there any opinions of using the T3 with full sized headphones? Specifically Beyer DT770's 600ohm or Denon D2000.

It can drive the D2000 to good sound and decent levels, but at higher volumes it seems to run out of current and distort some.  It actually sounds pretty good with my 300 ohm HD600 (took me by surprise), but it doesn't get very loud with my 600 ohm AKG K240M.  For 600 ohm loads I found the 3MOVE and TTVJ portable Millett hyrbid were my best portables on hand.

How large are the capacitors of the T4?

No idea.  Are you looking to upgrade them?  Not sure it's worth the effort for that last 2% of the sound.

They are Elna Silmic II 10V 47uF, fairly well regarded for coupling actually.

I have the non-dark grey top (behind the part with the iBasso logo), I heard they use the Nichicon 100uF caps, do they have the same size? And are they worth upgrading to 220uF?
And, what is coupling?

Yes, I am. PartsConneXion have them for cheap, though. Is it easy to replace capacitors? Will I need soldering skills?

No idea which T4 you are referring to, but I have a big doubt about the Nichicon 100uF since most 100uF cap is too big to fit into T4. 200uF is just close to impossible. You don't seem to know much about what the caps are used for nor have any soldering skill. I will advise against any moding until you know what you are doing or what goal you want to achieve.

Thank you for your honest advice.
Replacing the battery, however, do I need soldering skills?

Unfortunately yes, you need to know how to solder to replace the battery.
