HifiM8 has no line in or line out.

Don't know how more people don't notice the extra low bass bump on it, I've tried three different ones w/ different phones and it's always there. Either my ears are sensitive to it or others like it.

Maybe a C5? $:-\$

So what do want from a complementary amp? If you mean a contrasting signature try the Portaphile 627. Low battery life though. Cesar is great, he might let you try it out.

IF the vrms of ipod is so high that i'd have to use the headphone jack into the amp,
then it doesn't really matter if I use a sansa clip instead right?

I have no clue what output the Sansa Clip has...

You can use it with a LOD, however, as I said earlier... If you just want to use it with high-sensitivity low impedance cans/IEMs it's much better just asking Vorzüge to lower the gain on your amp. As simple as that... And no worries since you'll be using the more linear part of the volume potentiometer...

So about this vrms thing, if i am using high impedance cans/iem, then it'll not be a worry if i'm directly using the lod of the ipods without lowering the gain on the vorzuge amp?

I'll wait for the reviews. I like the form and size of the Pico Slim and the C5. The price of the C5 is very attractive. The basic CMoy BB V2.02 with 2227 I had was already pretty good i.m.o. Given the impressions I've read that the CMoy BBs have already been improved up on I'm very curious...

The Portaphile 627 sounds nice, and it's definitely on my list of considerations now. However reading AJ's shootout of portable amps, he scored it pretty low in background. Said hiss became very audible at higher volumes, which makes me weary of it.

I've also come across a company called Just Audio that isn't mentioned as much as some of these other guys. They have a class A portable amp called the AHA-120 which seems really interesting, and best of all can be custom ordered with 0dB gain for really sensitive IEMs.

http://justaudio.co.uk/aha-120.html

Read some reviews which say its fairly neutral in balance, high resolution, and has a very long battery life. Cons seems to be its huge size and some channel imbalance at very low volumes due to the volume pot.

The Lisa3 interest me... care to take a stab at the Lisa3 vs. the Mk III?

Okay, so I accidentally deleted Anax's last post.

Basically he said it seemed odd that AJ would rate the Portaphile low because it was his reference for a while. He said the Just Audio uHA wasn't very good (fuzzy sounding) and recommended the Lisa3 instead.

Sorry about that, Anax.

When I said AJ rated the Portaphile low I specifically meant the hiss factor, which he gave a 4 out of 10. The overall score for the amp was pretty high tho.

Here's what AJ said about the uHA: "doesn't add anything to the signal path other than what it should: more power and control. The transparency is very good as the uHA disappears and isn't noticed like other amps are, but the other amps get noticed for adding dynamics and punch, or giving a brighter or warmer sound, or even adding space. "

No worries.

The uHA was definitely on the warm side to me. Purrin has heard it but long ago. We had the uHA-120, Stepdance 1, Leckerton UHA6 mk1, and O2 side by side. Might have been another one in there but obviously if there was, it wasn't memorable.

Lisa3 w/ the PS is pretty nice, maybe best 'portable' I've heard but it's really a desktop amp pretending to be be portable so you have a whole other set of amps to consider at that point.

Did you give the UHA-4 a listen?

Agreed , LisaIII is one class act , it is as Anax said , more transportable than portable though. I am sure a smart board designer could convert it to a 4 layered smd board but battery life would be a major problem with the current draw.
