hey, i am new here and my english isnt so good...

anyway, i want to buy the best portable IEM/AMP/MP so i wanted to know what do you think about Samuel's Predator? will you suggest me to buy it ?
i am listening to Classical music and would like to have the most neautral sound - will the predator give me that result? is it the best potable headphone amp for my needs?

i would also would like to know - will the AOL cable will be the best to transfer the signals?

and would you suggest me on the iMod as the best portable mumsic player?

Of the two amps i have i prefer the iqube mostly for its neutral sound!
is lil more expensive than the predator and has no DAC but is a gorgeous sounding amp that drives everything i've ever thrown at it

Mini3, absolutely excellent. The price is excellent too .... $150 from Rockhopper Audio

Rockhopper Audio

The Mini3 Amp ...

The Mini³ ("Mini cubed") headphone amp is a new dynamic headphone amp from AMB Labs. This little powerhouse amp is the perfect companion for your portable CD player or MP3 player. It runs off of one rechargeable 9V battery and features an internal charging circuit so you don't need to remove the battery when it needs charging. The circuit features a three-channel active ground design that can power high and low impedance headphones with ease. At 3.15" x 2.125" x 0.91" it's the size of a very, very, very thick credit card, but you won't break the bank on this amp. At $150 this amp is a steal!
Features:


•Uses the Analog Devices AD8397 opamp for the left/right channels and the Burr-Brown OPA690 for the ground channel.


•Power switch built into volume control for ease of use. (ALPS RK097)


•300mAh 9 Volt rechargeable battery included with charger wall-wart. (~10 hours run time, will vary with application)


•Small size for portability.


•Signature orange LEDs (penguins like orange man).


•Active ground channel helps reduce stereo crosstalk, lower output impedance and clean up the signal ground channel.


•Classy Hammond extruded aluminum case. (3.15" x 2.125" x 0.91")


•Custom Front Panels from Front Panel Express (text says "Rockhopper Audio: Mini3) on the front.


•Sexy aluminum knob.


•Choice of Gain:


◦2 for IEMs and low impedance headphones


◦5 for low and high impedance headphones


•Black Chasis with Silver panels (above picture not representative, new pictures coming soon)

First, the overall synergy of equipment and source files is a factor in any advice you get and any application you make of that advice.

That said, I use FLAC through either an iRiver lineout or, when at home, through an iBasso D1 DAC (opamp 6241) for bedside listening.

Even when at home (i.e. using the iBasso DAC) I use a portable amplifier (having tried out many over the past 18 months or so and not finding an iBasso D1 opamp configuration that'll match the following amps).

My preferences with the above rig, feeding either Apuresound ER4Ps or Livewires T1s is:
1. Xin Supermicro IV
2. Xin Supermicro III (upgraded close to IV)
3. RSA Predator
4. RSA SR-71
5. Headamp Pico (with USB 24/96 DAC)
6. FordGTLover Panasonic Caps High Gain Mini3

The list is in order and all amps had achieved their required burn in (e.g. the Predator had 1200+ hours on it). The differences, overall, in SQ are small but noticeable - and in some ways it's characteristics or sound signature, as much as clarity/transparency/neutrality - for instance I find the RSA sound signature to be stronger in the midbass area, providing a warm sound, whereas the Supermicros punch out a deeper bass.

However, even with the differences, you will find what works best for you, your ears, and your sound preferences. For instance I recently had the others out and was using the Mini3, a delightful amp I instantly embraced when I first got it.

It still sings well, just not as well as the others and I rapidly reconnected in my supermicro when it returned.

Hope that helps.

The new minibox e+ with the red buttons instead of the switches do not have the opamp sockets for rolling. I recently opened mine up after looking to buy an AD797 op amp. Found out there was no socket like the pics I saw of Mr Arroyos minibox e+ insides. Looks like they are soldered in.
