Bill,
Your identification is accurate concerning his part selection. he does emphasize however that you have to properly mix and match these parts. For example he really likes the Blackgate capacitors and Audio Note non magnetic Tantalum resistors. But says too many of them can be counterproductive.
Bill, I know that you specifically will appreciate this. He believes in proper wire orientation. He says through listening, wire does indeed sound better in a particular direction. He knows this is controversial (For some) but doesn’t care, he bases it on what he hears. This stuff takes time. Just another reason why it is a 3 month build commitment. I know that you would understand this approach.
He and Graham, the builder of your Tron Audio DAC share overlapping philosophical beliefs. BTW Bill, when Abbas utilizes transistors, he sonically prefers vintage Germanium over silicon.😊
