battery powered with 'vivid' sound

I've experimented with battery power quite a bit over the past year, using the Dodd pre, Musical Surroundings Nova Phono Pre and a BPT battery power supply for the Squeezebox. I've generally concluded that if you have clean AC power available to your system, the benefits of battery power are largely overstated. The Dodd Pre is excellent and was dead quiet - but so is the VAC Renaissance MKII that I currently use. I still had some noise and hum issues with the Nova, so battery power is not a panacea for the ills that often affect phono pres. Also, you have to consider the inherent maintenance (battery replacement) and possible listening restrictions (need to recharge, etc.) in considering going with battery power. All in all, I've decided to move on from battery power for the time being.

To the original poster, I will say that in terms of sonics, the Dodd pre would fit your needs precisely. It's an excellent piece.

I have found that even with a RSA Dmitri/ full Isoclean system hooked up to my system that it never matched the glory of my system being completly off the grid.

I will never go back to AC after hearing what I have now in my system.

I have the Dmitri still but use it only for my Mac./TV./SAT./DVD.

Power conditioning technology is mostly a band aid for something that is - in my opinion - the single biggest problem in hi-fi. Much like up-sampling and re-sampling, if the source (in this case, power) is garbage, you can only do so much to clean it up. Even the PS Audio conditioners that regenerate AC are only 60-80% efficient. Besides, is there a single piece of audio equipment that natively uses AC power? No, everything requires DC power.

AC is useful for most uses in a typical home - appliances, lighting, etc. But hi-fi is a critical application of DC power - why on earth should effort be wasted on trying to extract it real time from garbage AC when battery technology now exists to bypass it?

Zam,

Well said. Sad to say this bit of truth will fall on deaf ears.

When I heard my system off the grid I knew I struck gold.

I would not give up on the 30.2 so fast as I know it can ROCK!.

Shazam, buy any amp you want and run it with this power inverter.

However, I spoke with an amp mfg recently and he told me sealed lead acid batteries are notoriously noisy FWIW.
