@cundare2 Sorry, I just meant the Margules ACRH-4 only uses single ended inputs and outputs. It’s Class A/B push pull with a tube hybrid buffer stage.
I understand your concern regarding quality control and discussed this with the Margules team and the US distributor a lot this year. They have since made some really good improvements in the gear and the last shipment of product I received was on a much greater level of fit and finish than before. Let’s say I had my moments of frustration in the past.
Cambridge has a stigma of being mid-fi, but they really did something special with the EDGE line of electronics. I still stand by it, that it performs even beyond its already higher than typical pricing for them, but delivering beyond compared to the competition at the same price. I’d pick the EDGE A over the Ayre EX-8, for instance. I think the EDGE would sound more musical and engaging while still retaining the razor sharp incisive holography that Ayre typically brings
I’m not trying to sell you on the EDGE, but rather just give it the respect it deserves when many others dismiss it because it’s associated with Cambridge’s mid-fi track record.
