Review: Portable amp roundup! 56 portable amps reviewed and compared - FINAL update 12-20-10... - Page 99  

eagerly waiting for the review of the headamp pico xD

The iBasso P2 is a small amp, about the size of a pack of regular-sized cigarettes, that has a 3 position bass boost and a 3 position gain switch.

It has rechargable lithium batteries via a 12vdc adapter, and is built using a 4-channel architecture.

It has socketed opamps so they can be changed to suit the users sonic preferences, however the buffers cannot be changed, only the L&R channel and the ground channel opamps are socketed whereas the buffers are discrete transistors.

IMO, it is a fine sounding little amp.

Skylab are you going to do Headamp Pico vs The Predator review and will you also review the DAC of the amps

OK Shopper, what part of Sky's explination did you not understand about why he has not reviewed the P2 yet

2 questions

why isnt the ibasso d1 in the review?

how does the bass response compare between the d1, uha-3 and lyrix? I'm gonna get one of them.

[QUOTE=
If you scroll back you will see that IBasso asked me not to put the D1 in this review, since it was designed to me more of a DAC than a portable headphone amp. So I reviewed it in another thread.[/QUOTE]

I see... I read the other thread (very helpful btw). Can you make any more comments on the D1's bass? You mentioned it's impactful. In your review of the UHA-3 earlier in this thread you called it a "bass monster" or something like that. I'm trying to decide between these two and the Lyrix. Since my 595s have little bass, the bass quantity is pretty important to me.

thanks for the help skylab. The Lyrix you reviewed; I believe you called it the Headphonia. Unless I'm getting it mixed up with something else I think it is no longer discontinued.

With the AD797 opamps in LR and AD8397 in the buffers, the D1's bass is very strong. The Lyrix bass is very strong even with no changes from stock. The D1 is an audibly better DAC for my home setup, but you'd be happy with either of them (I am) being driven from a laptop.

PS: The Lyrix is a new design and is not the same as the Headphonia design.

wow, thanks HeadphoneAddict, just two more for you....

How do you like the crossfeed/bassboost on the lyrix

and

Where do you get the opamps for the ibasso, I think you mentioned how much they cost in your review, but not where i might get them...

I don't like the Crossfeed on the Lyrix, nor do I like the xfeed on my Xin SuperMacro 3 which is supposed to be as good as the Meier. It takes away from the ambience. I haven't heard the Meier crossfeed yet, and I haven't built my modified Linkwitz crossfeed for PIMETA yet. I also have the panels and circuit board to build a Meier Corda Cross-1 but haven't started yet.

The bass boost is great for certain headphones, like ER6i, but I don't use it much otherwise. Sometimes for fun I'll turn it on for my HD600 or RS-2, but they don't really need it, as the stock bass is plenty.

I got opamps from HiFlight and Souperman here on head-fi, and from Newark.com like this one TEXAS INSTRUMENTS | OPA2111KP | Analog & Mixed Signal ICs | Semiconductors & Prototyping | Newark.com

Skylab, I have the orig. Larocca PRII with blackgate caps. How much is it to upgrade to MKII? How long did it take? And was it worth the money to you? I haven't surfed here much recently though and am not even sure Larocca is still in business as I now see he's the engineer for Triads Lisa III....maybe he's not supporting the PR anymore? (just in case I decide to sell the PR, any ideas what it maybe worth? It's mint.)


Thanks
