Thanks. Any thoughts on the quality of the bass boost feature?

This should give you some idea.

I wanted to thank to OP and other technical reviewers on HF for their analysis of budget-conscious/economical portable amps. This particular review is packed with enough info to help people make informed decisions. I ended up skimming the whole thread and reading about half of it. I'm glad I did. If you're a newcomer to portable amps, it's worth skimming and reading this thread.

 

I ended up getting a Leckerton UHA-4. This is a nice package for the money. Definitely portable. The rounded edges don't catch on pants pockets (however the cables will). It drives my AKG K271 with ease. The OP is correct, no noise floor.  Bravo! I do detect a little bit, let me repeat a little bit, of graininess on the highs while listening to some music but not other music. Mids are solid. Considering the voltage this amp delivers, the basses are delivered.

Just read your review of the C5, and it does make me question my FiiO E12 purchase :|

 

How much "better" is it compared to the E12, and is it worth the price? I already love my amp but I do admit the soundstage could be better as well as needing a bit more treble sparkle.

C5 sounds more neutral / less warm than E12. But the technical difference isn't big in anyway. If you are happy with E12, I think the smart thing to do is to keep it, especially since C5 is not big in soundstage in anyway so the one area you want the most 'upgrade' won't be there.

True, true. I love the dynamics of the E12 already but of course with this hobby there's always something better out there and thus upgraditis kicks in :P

 

How more neutral is the C5 by the way? I could always go for a more neutral sound sig to counter the slight midbass warmth of my new SRH840.

C5 is more neutral, but still a bit forward overall. For a rough figure, I think I'll call C5 about 60%~70% forwardness of E12.

I bought the O2 after reading this review.  Thanks!!  I paired it to a Beyer DT880 250 but think it's still on the quite side.  Need to crank it up.  Not really using it efficiently - double amp'd with an idevice.

Does anyone have any experience with the HRT MicroStreamer?

 

If so, could you compare to the top three in the shootout?

 

Other general impressions are also welcome.

I don't own any of the top 3 here, but I have an E11 which seemingly comes close, and it is nowhere near as dynamic with my HD650 as the uS headphone out.

I won't say E11 comes particularly close to the top-tier. They are much obvious ahead of the whole pack.

ClieOs you think a Jds C5 will be able to power a beyer dt 880 600 ohm? My old cMoy BB powered the 250 ohms very nicely from what I remember 

 

Wondering if the C5 will be enough... I've got a month before my Hm 801 comes in, so hopefully if need be I can try to sell it off, For better or worse I've also sent my C5 off to have it's bass boost... hlaved [factory adjustment John offered me himself] in addition to having the newest firm ware loaded

Don't have any 600 ohm to test it with, but I would think it might not have the power to drive 600ohm properly consider it doesn't have a lot of gain (more important) or current (less important). Since it is on its way back to JDS, you might want to ask John if there is room to increase the gain or not.

 

update: just checked Xnor's chart here using DT770-600 as a model (they have similar spec), and the C5 should be okay.
