True Fully Balanced Amplifiers


What are the least expensive true FULLY BALANCED power amplifiers available?
Adcoms, Rotels, and Parasounds have balanced inputs, but are not truly balanced.I have an Adcom GFP-750 that is Fully balanced and would like to try it with an amp that is also fully balanced at a reasonable price.

Musical Fidelity uses dual-mono construction. I asked them if they planned to offer a balanced amp. They told me the sonic improvement, if any, was not worth the money it would cost. This was based on listening tests.
Maybe the dual mono design is the reason.
Zaikesman, the Pass Aleph 5 is a balanced designs employing employing 2 gain stages.
Zaikesman, I could be wrong about this, but, I believe Pass uses one sigle ended push and one single ended pull per channel, to provide "symmetrical" single ended balanced designs. Does seem like an oxymoron, doesn't it?
Aragon makes true balanced amplifiers. They have quite a few excellent ones to choose from too.
