After explaining my motivations and goals, Ben very patiently let me try many different dacs, power supplies, interconnects and power cables, without trying to impose his own preferences, but more gently steering based on my feedback after each listening session.. When it came to arranging home demos, it was very straightforward, and given all the time I needed to figure out what best worked at home. You don't come here for box shifters, but for personal service, and this is what you get, no pressure selling, very friendly, obvious these guys are hifi buffs themselves. An easy 5 star recommendation.
