Multi-Portable Amp Thread: 12 amps reviewed (Shonyun 306 added 10/03/12) - Page 6

Looking forward to your review. I've been eying this one for a while. Will you be testing this with the SA-43s as well?

Hi Joe,

Just wondering if you have by any chance listened to the Leckerton uha-4?

I'm deciding if I should be getting that to pair with my 8As.

Thanks.

I am kinda curious how the Headstage Arrow 4G has improved compared to its previous iterations. I am looking for a great slim portable headphone amp for my IEM's, and am awaiting a pair of AS-1b's in the coming days/weeks. Any suggestions? The Arrow really is my target pricepoint. But I would be willing to spend more if their is an obvious better choice

Thanks for the help, does that mean you are testing out the G4 now? and the pico slim isn't still small? or is their a huge difference?

Was mainly curios about how it performs with high-sensitivity IEM's and IEM's at low volumes, as those seem to be the major re-occuring complaints about the G3. If you could let me know that would be awesome. Love this thread, very excited to get a new amp soon.

Hi joe,

May i know is the cruise suitable for iem use? and which CIEM (NT6, ACS T1, or H.A. 8A) will benefit most from the cruise?

Thanks

Sorry for interfering the hi-fi discussion but I just have a few questions about the iFuzen HP-1. Do you know what the "sound modes" are? All I can find is that it's supposed to match your headphones. What does low/high power actually mean? What specs would run better with which setting? Impedance, sensitivity etc.

Amps are known to benefit headphones more than IEMs because a lot of them need additional juice (because BAs are more efficient).  Because of that, do amps benefit DD-based IEMs more than BA-based IEMs in general?

Interesting...Thanks!

That's not entirely true. Both of the jacks work with all of the sound modes. It just boils down to the impedance and sensitivity which jack and sound mode you should choose. I'm always using the low gain jack since my phones are either budget IEMs or my K271mkII which aren't hard to drive at all. I just had to try right now and with the different gains in the jacks, that leaves us with 8 combinations. Someone with good ears tell me the difference? ;) I contacted Auzentech about the vague descriptions on sound modes. All he had to say was:

Dear Simon,

Thanks for your purchase of the i.Fuzen.

The soundmode is a hardware modification of sound (not equalizer) to
customize the i.Fuzen to match the characteristic of your headphones.

Sincerely,

Jay DeWalques

Which really isn't helpful at all. I tried asking again about specifics or if that was a company secret. Haven't heard from him again.

So while I think it sounds a bit like equalizing, the company says it's not. So with that information. Can anybody with more knowledge figure out what "hardware modifications" are made?
