Graham Slee Solo to Solo Ultra Linear upgrade

This page used to be about upgrading your Solo to the Solo SRGII, but now, for the same price we'll upgrade you to the Solo Ultra Linear.

Earlier versions of the Solo headphone amplifier housed in the same enclosure as shown can now be factory upgraded to the Solo Ultra Linear.

"...Then there is the low end bass. Marillion uses synthesizers to add low end bass and give some songs tremendous scale (like movie soundtracks). The Ultra-Linear delivers it in spades and with detailing. Without clouding the rest of the soundscape..."
[Solo Ultra-Linear, Owners Forum Review]

The Solo Ultra Linear headphone amplifier factory upgrade involves fitting a completely new fully tested PCB assembly. It is in fact like getting a brand new Solo Ultra Linear headphone amp but reusing your existing case.
