Ibasso D4 / T3 Review Thread

[nycdoi]

i thought this thread gonna be about d4 and t3. how come there are T3 talks only.
im interested in the d4, but i dont see why it is $50 more expensive than d2 yet it is not better than d2(according ibasso's description).
Care to explain anyone? im too lazy to read the other thread about the d4

Thursday in USA is Friday in China so you are ordering it at the end of business week. so they probably still processing the order, I bet the quickest they can ship it is their Monday which is like evening of Sunday in USA.

well...I havnt received mine yet. However check hiflights review thread. It is way better than the D2, it has more power and dual DACs, where the D2 only has a single.

The D4 is excellent sounding. The frequency spectrum is clean, the bass is solid and deep and the separation of voices and instruments front to back and side to side is very good. I look forward to other peoples impressions.

Maybe it's a novice question, but what exactly is a second DAC going to do for you? Is it one DAC per channel (L/R)? Otherwise it seems a little redundant.

 

[jamato8]

It is one dac per channel.

I forgt about that. Stupid intl. date line. Well I'm leaving for Miami tomorrow so hopefully it's here before I get back.

So does anyone know if the iBasso T3 still boosts the bass by 2dB like the T4 did (with the switch on) or not?

there is no bass boost switch on T3 other than volume the only thing adjustable is the gain

tried T3 with PFE gray filter+Olive today. it increase the bass on PFE and added a little warmness to the sounds which make PFE less harsh and smoother to listen for longer time.

to UM3X, T3 add a little more warmness too but the high/treble resolution increase. stronger bass is good but the depth isn't enough for increase quantity. maybe I should let it run a little longer (only20 hours so far)

regard the battery life, it is great for little amp, longer than E5 and my Clip+ and 5800 combine (8 hours and 12+ hours) that is the charge left by Ibasso and a full charge will be much longer.

do these pick up RF signals like the otheR Ibasso amps?
I currently own a D3 and this thing goes bonkers in public

Great question, something I'm curious about as well...

 

[turnstyle]

In addition to RF...

1) With sensitive IEMs (such as UM3X) is laptop > USB > D4 > IEM -- silent or is there some hiss?

2) Again with sensitive IEMs, is the volume left/right even at low volumes?

thanks!

 

[jamato8]

I go all over the place with my T3 and no interference but I guess some areas vary on the amount of interference.

On hiss, on low gain, which is all that is needed for IEM's, I get zero hiss with UM2's and zero with the JH13's.

I have still to figure out battery life on the T3 as I have left it running for a couple of days at a time and it was still going.

On burn in, yes 100 hours or more to totally smooth out and everything to fall into place in the frequency spectrum.

And, in low gain with your UM2 or JH13 -- is the left/right volume equal at low levels? I understand this to be a common problem with some volume controls, so I'm wondering how the D4 does -- do you know what kind of volume control it has?

And just to be sure, when you said "On hiss, on low gain, which is all that is needed for IEM's, I get zero hiss with UM2's and zero with the JH13's." -- was that with the D4? (from your post, looks like it might have been T3)
