What you are looking at is a scalled down, non production version of the Purity Audio Design Harmonia 300B vacuum tube source buffer but with the addition of a 4 input relay based source selector and volume control. By scaled down, this means it is a single ended unit only and built into one of our remaining Musica bella Spitit linestage chassis. This is not a prototype.
We are considering bringing this model to market this summer after having chassis' designed.
The Harmonia BP is designed as a 300B buffer output stage for any source component. Can also be used as a preamp to be used into a power amplifier but may cause noise in higher effeciency speakers. See details below.
DETAILS: Price does NOT include 300B tubes or power cord. Shipping included to lower 48.
