I've done some research and I believe these two are the best available for anyone who is using a high current pedal (450mA or higher) on their board. I think I would be good with either the Zuma or the CS12. An advantage in noise reduction/noise rejection would sway me. Isolation and noise-wise, Truetone is secretive about their technology and Strymon provides information that most will not really understand (or care to). My take is that these devices are fairly equal on this level. Truetone 1 Spot Pro CS12 – with Isolated Outputs - $179.99 (list) http://truetone.com/power-supplies/1-spot-pro/1-spot-pro-c12zzz/ 2 - 18v 100mA 4 - 9v or 12v 100mA (switchable 9 or 12 volts) 1 - 4v through 9v 100mA (variable range voltage) 2 - 9v 250mA 2 - 9v 500mA 1 - 9v 800mA (AC only) Strymon Zuma - $249.00 (list) http://www.strymon.net/products/zuma/ 7 - 9v 500mA 2 - 9v 500mA – switchable to 12v 375mA or 18v 250mA 1 - 24v out to integrate additional Strymon power supplies What do you think? To me, any brick that lacks at least one 450mA out is not qualifying for modern day elite. Units listed below have been added to the elite list (as a result of posts to this thread). Cioks Ciokolate - $369 (list) http://cioks.com/index.php?option=com_content&task=view&id=58&Itemid=73 13 DC and 3 AC (16 total total/ports) in 12 isolated sections 3 - 9v 100mA 1 - 18v 100mA (switchable to 24 volts) 1 - 4v through 9v 100mA (variable range voltage) 2 - 9v 200mA (switchable to 12 volts) 2 - 9v 400mA (switchable to 12 volts) 1 - 9v 400mA (can be used in a combo) 1 - 12v 400mA (switchable to 15 volts) 1 - 9v 600mA (can be used in a combo) 1 - 12v 600mA (switchable to 15 volts) 1 - AC 9v 800mA (switchable to 12 volts) 1 - AC 9v 800mA (can be used in a combo) 1 - AC 12v 800mA (switchable to 16 volts) some ports can be combined to create a single 40v port Gurus Power5000 - $399 in the USA http://www.gurusamps.com/en/products/power5000 Like a Strymon but beyond. Has an on/off switch. 4 - 9v 500mA each 4 - 9v 500mA each or 12v 400mA each (switchable voltage) 1 - 9v 1000mA with adjustable voltage under 9v 1 - 18v 200mA with adjustable voltage under 9v 2 - AC 12v with 1000mA max per port Voodoo Labs Pedal Power 4x4 - $189 (list) http://www.voodoolab.com/pedalpower_4x4.htm 2 - 9v or 12v 400mA (switchable) 2 - 9v 400mA 4 - 9v 100mA (can be used in a combo) Yankee PS-M12 - $245 (list) http://yankee.com.pl/ps-m12-power-supply/?lang=en 5 - 9v 900mA max per port 1 - 6v, 12v, 18v, 24v - switchable voltage - 600mA max 1 - 6v, 12v, 15v, 18v - switchable voltage - 600mA max 2 - AC 9v (1) and 12v (1) - only one at a time - 1200mA max Yankee PS-M24 - $575 (list) http://yankee.com.pl/ps-m12-power-supply/?lang=en 24 ports total, 18 ports can be used at once Elite unit on pure magnitude of a single device, however, at that price point, value must be questioned. Two Strymon Zumas would require less coin. Notables that don't make the cut...(IMHO). MXR M238 - $149 list. Maybe "budget elite?" Unique to this unit are two variable voltage ports that range from 6 to 15 volts. The LEDs are a plus. The most troubling element is that this device uses a wall wart. That's a potential point of failure which puts this one in a lower tier. For another $30 you can get a Truetone CS12. Yankee HS-M12 - $399 list. Versatile but in two sections you can only use 1 of the 3 ports at once. That makes this a very expensive 8-port power supply Yankee HS-M10 - $319 list. You have to download the set-up PDF to discover that this unit isn't close to the HSM-12 and is only $80 less..
