Tube Monoblocks w/- balanced inputs?

Budget?

Thanks for your input folks - my sense is that, with Maggies, more power is always preferable.

He's confortable buying used & I think was hoping to get a monoblock pair for between $2.5 - $4.5K used.

Ok, apparently a little higher than quoted above if necessary for a good match ...

Atmasphere monos if your friend is OK with OTLs?

You havent made clear if your friend is simply looking for balanced input connectors or true balanced/differential amplifier circuits.

Balanced circuit:
100wpc Manley Snappers

Balanced Inputs:

Manley Neo-Classic 250(wpc) monoblocks. Just out of range, but someone has a used pair listed here for $4,850.

Antique Sound Labs Hurricane DT Mark 2 (200wpc). There's one listed here for $3,900

Rogue Audio Zeus (225wpc). A bit out of your friend's range, but worth considering used at $4,900. Used M-150 or M-180's will likely be within his price range.
