Does anyone think this amp can drive the RE1s well?

Hmm then maybe I should get the minibox. I'll be using it with a zune and pk1's and so far, unamped, my pk1's already feel really bassy and very nice lows. The highs are good too, but I love highs and more detail. I wouldn't mind fatigue, I don't listen to music 24/7, and I love the "grado sound" which seems more harsh and has more highs then most cans from what I understand.

I'll think on it though, the T4 looks like it has better build quality and more practical. Hmm, sounds like a hard choice.

I am not getting the bass being discussed. I am hearing what I consider normal bass and I am also getting good detail. This is with an iRiver and lossless or my Monica II dac. I will do some more comparing on the bass quality.

There is an obvious bass bump when switching from the Minibox-D to the T4 using ER4S. Using my PRO750 the difference is subtle. Lol.

Detail-wise.. There is a recording I have where the singer pauses for a moment. Using my Minibox-D I can hear the echo of the last line he sang before he paused. But on my T4, that echo is barely existent. On another recording I can hear that same vocalist er.. swallow his saliva and also hear that sound which made by our lips when our mouth opens and closes via the Minibox-D. On the T4 on the other hand.. These things do not exist. Both of them are acoustic songs. Listened at the same level.

Actually now that I think about it more....I'm considering the T4 more. For one thing it has a bass booster switch, I might not even need it, but I'd like the choice, whereas minibox-d doesn't have one.

From the measurements it looks like the T4 is smaller, and I like how it's edges are slightly rounded, that would help with putting it in and taking it out of your pocket.

To me it just looks more durable too. Now I guess I just need to come up with the money lol.

Both them are equally durable IMHO. But the T4 is just more pocket friendly. Rounded edges, smaller size. 10mm thickness. What's not to love about it? Except the battery life. Lol.

Personally I've heard no change after my "burn-in" period ever since I've got it.

I just got mine today and its charging.

I actually never understood it was only meant for in ear phones.
I got it partially because i just bought an EU classic120 and want higher volume, but also to drive my k-171´s.

It cant be worse to drive them with the amp then without the amp?
In normal hifi, the only thing you damage when using a low power amp is the speakers. In this case, i cant see why the speakers would suffer more getting the extra watts from the t4?

It says in the manual impedance 8-300ohm.

The only thing I can say about why people use amps for iPods is that they want to bypass the iPod's internal amp and use something of better quality. That of course, depends whether you can hear the difference.

I know the k-171 is not expensive phones, but i got them cheap and i do think they sound good when one first listen to them a bit. They have tight nice bass and are "neutral" i think for the price.

Now i just listened a little on the T4 because it just finished loading. It immediately put a smile to my face.

To me, the sound is not neutral, but it is upped in the mids, high mids and bass. It sounds warm.
This is not a bad thing, because its fun to listen to and this was exactly what i was after. It gives the music warmth (life), and i can get higher volume.

I "have" to use the gain on the Akg k-171´s if i want some volume, to bad because it sounds abit better without it on. Using the bass boost did not make me happy, it didn't just up the bass but the entire lower registry, its kinda like loudness i think but not so bad.

I can understand why some like it and it might give my d-jays what they need, but with the 171´s i loose the tight and controlled bass i think so itsvery nice to be able to choose on and off.


I like the amp alot, they have made the right choice in the sound because its about having fun and especially in this pricerange its not about total neutrality imho.
I will test it more when i get my LOD, this quick test was done with the HP-out.

hey everyone,

newby here. I was also enquiring about this amp on my thread so maybe you can help me.

for those who have the T4 , do you think I will get a noticeable sound difference when using it with super.fi 5 pro and ipod classic?

I am in the process of choosing IEM's as well. my two choices are super.fi 5 pro and shure SE420. However, after getting some advice here on the site I am leaning towards 5Pro and with the price difference getting T4.

thanks.

zeph, did i read somewhere that you have also bought recently a Sony s639 player?? If so, when it arrives any chance of a photo of the amp and player together? Plus impressions on whether or not the 639 needs amplification, or what changes the T4 makes to the sound from the s639.Cheers bud.
