Is anyone enjoying deep house from their L300/L500 or is this just wishful thinking from my part?

I'm possibly going to swing for a pair of these the 3100 setup seems like a really great idea, but first I want to know too, is this capable of putting out a full range of dynamic music and can it handle a wide range of genres?

Surprisingly, it does handle a wide range of genres well for an electrostatic with good bass. Actually, i don't really want more bass the standard l300 pads do a great job balancing all frequencies.

Electrostatics are unique and niche. I have spent last few weekends just sitting down and being one with the music for several hours.

It's a totally different experience to dynamic drivers.

Car battery would do, but too big I guess. what I use is http://www.tracerpower.com/tracer-lithium-polymer-battery-packs.html 12V/10Ah. Comes very handy with a charger. BtW I bought it too big, airport transport restricts this size (i.e. more that 100 Ah), hence suggest 8Ah version

I'm looking at http://www.tracerpower.com/12v-8ah-lithium-polymer-battery-pack.html
Doesn't seem to come with a 5.5 X 2.1 mm plug.

They do sell the plug, but I think it's center positive:

How long can the 10Ah battery power SRM-252S for?
Click to expand...
Ridiculously long, at least 1 week a 8h in the office. Some Maths we have E = 12 x 10 VAh = 120 Wh. Nominal power 252 4W (as per specs), means 120/4 = 30h.
This latter number is high I guess, since I get certainly 40h.

(PS currently too lazy to measure current of SRM 252)

Battery is supposed to have about 70% efficiency, so out of 120Wh, only about 84Wh should be available to the consuming device.
I guess SRM-252S usually takes a lot less than 4W.

I wish somebody could measure the noise levels on such battery - just because it's a battery, doesn't mean it's noise free.
If it's quieter than using iFi adapter (which I ordered), I'd buy it too.
I'd probably buy even if it has comparable noise - which should still be better than Stax adapter + Kashimura transformer.

In my opinion, L700 pads destroy the magical balance of the L300.
I immediately sold my L700 pads, and the person I sold them is selling them too!
Maybe we're both deaf...

Maybe that's because you didn't do the most important mod, that is totally required when using L700 pads on L300?
It is a bit complicated though...

So you don't just snap on the pads? Not one for complicated mods so maybe not worth it for me.

I've seen people use ZMF and Brainwavz pads on the L300 and they don't say the sound changes s not sure why the L700 pads would do anything besides make it more comfortable.

I am not an expert re battery noise. But from my basis understanding, the DC potential generated by a battery is a consequence of chemical processes, hence noice would stem from the respective chemical processes (except for noice induced by the environment). Is my understanding true. How would you go measuring the noise of a battery?

From my simplistic point of view, I am using the battery because it has a much higher stability for high current demands, which is typically a problem with cheap battery adapters. Independently of this theoretical background the SR007 I am currently using sounds splendid with the battery.

(edit - added)
Did some research - interesting to read https://www.mikrocontroller.net/attachment/100819/Measurement_of_Chemical_Battery_noise.pdf

I did not have time to study this in details, but it seems to tell me, that the noise of a battery is at least 20dB lower than a regulated source (see figures 2 and 3)
