The Headroom desk top too..

The XP has rechargable Pack installed. The Power Supply recharges and is a clean stable source for AC operation.

Does the regular Lisa III recharge the 9 volt batteries?

Yes it does, using either a wallwart power supply or the LLP power supply.

I'm looking for something along the lines of the Lisa, where you COULD carry it around, but it's more at home on a desk like the Lisa is. Listening to the Lisa III, I'm falling in love with the sound more than I initially thought, but am left curious if there's anything else out there that betters it that DOESN'T need to be plugged in. Just straight SQ, is the Lisa pretty much the end all BEFORE it becomes a "home amp"? Especially in that price bracket?

The LISA III is the best battery powered amps I have ever heard. I also considered it as the best amp below US$1,000.

From my limited days in this circle I have not found an amp the provide the combination of resolution, balance across the whole frequency spectrum, smoothness, transparency and organic engagement in one single package - until I met the LISA III.

In the early days of my LISA ownership, I quickly compared it to some of my favorite amps. For those interested, you are read it here :

Is the LISA III the best a battery powered amp can be ? - I would say almost. I am pretty certain the LISA III would be the pinnacle of opamp based headphone amp design. But I still believe the yet to come portacode (or whatever it may be named) will be another level of revelation in waiting.

Go no further I can fill most of the needs. :^) I do think there are portables that do a great job but it is understood by most manufactures that you still don't have that extra voltage for the ultimate drive of home headphones.

Me too. I certainly would like to see a "Home" version of LISA III - one that can works with AC supply only - with the ultimate in power supply regulation to provide the quality power and a step jump in voltage swing and density to bring listening to a new level. Of course, I would love to see multiple input, gain selector and better volume pot..... and yet in a package still "transportable" easily from one location to an other.

I can only hope Phil is watching this forum

Hey Guy's, when I connect the LLP. The battery's are out of the loop. It is a wonderful clean supply. You keep mentioning the dynamic swings and contrast. Have you heard the Lisa XP/LLP combo? You think Sennheisers are hard to drive? Any Stable Voltage base handles them. But the Darth's, if you don't have a stable current platform. And it's not clean and plenty on tap. The Darth's will wither and die, and sound horrible. They don't sound horrible with the Lisa.

I think Lisa III sounds better with LLP than without. I didn't get LLP, but I do use PSR with it.

You will have more than 1db drop in output when disconnected from the LLP.
And dynamics are stunted when on battery only. I recommend the LLP, because it is purpose made. Very very quiet, much better than a typical Wall-Wart.

How do the DIY/Open-source designs compare to the Lisa? How about a PPAv2?

I'm considering a DIY design for a battery powered transportable, and the Lisa size is about the size I would like to be limited to, so that probably helps out a little, lol. Battery life, etc, not really factors if obviously I'm putting up with the Lisa's short battery life.

 

[TzeYang]

the LISA III is more or less like a PPA V2 with two extra non switching bias current regulating diodes.

If you were to ask me, both are extremely similar. The PPA V2 does have the benefits of adjustable biasing though.

 

[oicdn]

The only thing I don't like about the PPAv2's is how TALL they look, as compared to the Lisa which is fairly slender. Also, all the PPAv2's seem to be wall powered....

I can't seem to find an estimate on how much they seem to cost from a builder. How CLOSE is the sound to a Lisa???

*edit* Like pictured below:

LISA III New Front Panel 019 - eSnips, share anything

I like how slender the new Lisa is, as it's not TOO bothersome to carry around. Carrying around that 1st gen Lisa, which appears to be the same size as all the DIY PPAv2 offerings, is just too big.

Basically, I need something that will primarily be a desk unit (ability to drive bigger cans, and will replace my portable as an "do both" amp), but HAS THE ABILITY to be carried in the pocket/bag AND has the bass knob. So battery life isn't a concern.

 

[ZephyrSapphire]

Well we can't say it's the best transportable yet since no one has compared it to RSA's XP-7 or Rudistor's NKK.01se

i've started saving for the portacode...
