Tube balanced preamp for class D amp?

I suggest the YS Audio Experience Balanced A2 preamp.

Simontju, as far as we know, Atma-Sphere offered the first balanced line products for high end audio, in the form of a fully-differential balanced-line tube preamp. One of the founders of BAT was a customer of ours before going into business for himself. Just setting the record straight...

Dear Athmaspere,

Your post is duly noted and I did not know this fact. Your products are uniformely prised and I am sure its one of many reasons behind it.

My attitude is that fully balanced amplification definitely improves performance but raises price for the end-user (in various degree, depending on the way of implementation) so if its top of the line SE unit,in theory, customer should have an option to select fully balanced configuration.

Regarding balanced inputs and outputs only - its not that big of the deal one way or another and francly depends on upstream noise....

Yours very truly,

Simon

I found this thread when looking at the forum today. For me I like the combination of a Bottlehead BeePre preamp matched with a pair of Red Dragon M1000 Mark 1 amps.

The Bottlehead BeePre has XLR outputs and my Red Dragon M1000s only have XLR inputs. I believe both are balanced so the pairing works great to me.
