Help with Portable Amp

post #1 of 9
Thread Starter 

I own the Grado RS1i and I am going to pick up a Sansa Clip+ for Flac and Mp3 files.

 

Which portable amp would you suggest for my RS1i...I listen to classic rock.

 

Fiio 11 or a cmoy ?

 

If cmoy any suggestions to which one.

 

Thanks for any help.

I went through this same debate some time back.  I got the Fiio E11 because of the rechargeable battery.  I was not disappointed.  It is quite a competent amp.  Plus, it's smaller.

I wouldn't recommend trying to run those off of a clip and a cheap amp. Most high-end cans, and in particular Grados, don't sound right without a lot of current. I'd say you are looking at at least $100 for a desktop amp (I'd go with a Schiit Magni, 1.2 watts should drive the Grados plenty) and much more than that for a portable-I've heard Ray Samuels amps go great with Grados, and they start around $300. As far as a source goes, you really want something with a line-out, which bypasses the internal amp of the source and cleans up the signal. That being said, if you are stuck on a budget portable setup, I'd say a C&C BH or possibly something from JDSlabs. If you rockbox the Clip+ and set the volume to +0dB, you have something approximating a line-out signal.

So I can go from my headphone jack of the clip zip to my line in on cmoy using a interconnect cable ....then plug my phones into the cmoy......correct

 

 

The RS1 sound decent straight to the clip zip with no amp....so I figure a cmoy should help for sure

Yes, Clip Zip with a 3.5mm interconnect to a CMoy will work. Do one of two things-set the volume on the Clip to maximum, OR rockbox it and set to +0dB. Rockbox will bring you closer to a line-out, but max volume on the Clip is still pretty good.

Great, thanks....can't wait to get the cmoy and try it out.

 

Is it worth it to get the 18 volt version so I can try all op-amps....also do you recommend the rechargeable batteries.

The 18 V version is only recommended for high impedance (> 250 ohms) because they need the extra voltage.  Low impedance headphones will not see any improvement with increased voltage.

There's also the PA2V2 and it might help the Grado sound as it is very slightly warmer with a decent soundstage. Reminds me of my fullsized integrated in a way. Battery I get well over 100 hours. Far as I know it is a high current amp. Has no issues driving most of my headphones including vintage orthos ( I set gain at 3/4 ).You can also get in there and adjust the gain screws at any point, but if you let Gary know what you will be driving he can do it for you and save you the trouble.

Guaranteed for life no questions asked.... and Gary ( who makes them ) is stellar with customer service, one of the greats.

If you ( for some odd reason ???) found it wasn't for you they don't last long in the for sale section here I noticed.

 There's plenty of reviews in here. Great little unit and reasonably priced.

Hard to beat as a "first" amp. Heck it's been my "first" portable amp for ages now just getting back into portable stuff again.
