my initial impression is that most of us would not like the preamps, and find them not adequate at all. Yes, they are in terms of supplying power, handling the signal and not distorting...
but anyone with a decent set of headphones, and coming off from another deck that does sound good...wont be impressed. Doug mentioned the dynamic range of the stock chips was somewhere in the mid 80db
range. His upgrade chip is about 40db more.
his upgrades are subjective... "its a warm mod"...is warm to his ears. However, having run many previous Oade mod'd decks....he's been consistent in producing a MUCH better product
than stock. So i'm IN.
