So, if you were an American buying a 240V-only box from Europe, would you:

1) just use batteries,
2) buy a voltage upconverter for the AC cord,
3) or buy a DC transformer

We all know choice #2 produces more power & sound than choice #1, but is there any noticeable difference between choice 2 and 3? If not, I'm just going to buy whatever's cheaper.

If you don't plan on carrying the box around everywhere, I'd just go with the DC adapter. However, depending on the box, you could be losing a lot of extra power.

totally,but in one case i didn't practice what i preach i use my crown,almost exclusivly on Batteries,I think i'll chg that!

the AC is converted to DC, +/- 1 to 2 volts, it makes no real difference except for how long it will run.

just stick with what's cheaper unless you have $$$

On my Telefunken HP-800 The 240 volt convertor gave me much better results than the DC power supply.
Cleaner and stronger power output.
Then again I was told that that particular box ran at half its potential when powered via batteries or 12 volt input.

Look at my post Here

AC is always better than DC as far as having steady current for the internal transformer. Some boxes have an internal (or in the case of some of mine external) switching when on batteries. My heavy duty ones like the Hi-Fi Studio, PC-55, CP-7, CK-5F and even the PH480 will have power output greatly reduced under DC alone via batteries or external brick. If it didn't have this switching ability batteries would be pointless in these systems. And in some of them the run time is so short if you apply any serious volume (current draw) and they're so heavy you wouldn't bother anyway.
