Iain, the person who builds these, made a pair to my specification at a fair price. The quality of work was of a high standard. I have no connection with the company or individual.
I've had excellent results using them to match genuine line level outputs (at a healthy 775mV) to equipment with input sensitivities below 100mV, particularly common on vintage gear.
As an aside, perhaps Haselsh1 would benefit from in-line attenuation before his Croft Micro Basic pre? He often says that he suffers from not having unity gain in his system.
