The EMP is much smaller and has a built-in recorder (only 16-bit, though).
I'm finding it hard to get info on the EMP, some places say it gets 4 hours from 4 AAs, some 8 hours. Size, weight?

The following is copy/pasted from a scanned pdf of the info. sheet I picked up in Frankfurt in May.
I hope it answers your questions (I really hope it does, it has taken me over half an hour to post this).
NAGRA EMP portable dual microphone pre-amplifierThe Nagra-EMP is a custom built external stereo microphone preamplifier. Using principally the same electronic schematic as the renowned preamplifiers of the Nagra Vl, it runs of 4 AA batteries. Equipped with a small built-in audio recorder, this extremely high quality preamplifier can be used in numerous different situations.
The Nagra-EMP is a stereo / 2 channel portable preamplifier designed for classical music and film / TV location recording. An 16-bit solid-state 2-track digital audio recorder is built-in (2 GB memory). lt is designed and built as an "on-location" recorder with the traditional Nagra ruggedness. All controls as audio limilers, filters, Phantom power, record are controlled lrom the front.
The front panel, chassis and features were all designed using the experience of previous NAGRA recorders which render the Nagra-EMP to very user-friendly and comfortable to operate even in harsh environmental conditions. lt is powered by a 4 AA cells. The autonomy without recording is approximalely 4 hours (No Phantom, no record). lt is equipped with one Hirose connector allowing external power.
The Nagra EMP has two analogue inputs on XLR connectors, equipped with extremely high quality microphone pre-amplifiers. They include, as one expects, +48 V phantom powering and in-house wound NAGRA transformers offering an improvement of +6 dB in the noise floor when set to the 2 mV/Pa (for dynamic microphones) position.
Equipped with a low cut filter as well as a Vortex filter and limiters.
