To the OP. I know you say you have low bass output from your new 840C. I also have a new 840C. The only upgrade I have is a PS Audio AC3 1M PC. I have never listened to the stock cord, so I don't yet know what difference the PC provides. Anyway, sometimes I think that the unit doesn't do bass so well, then I put in a different CD and voala, good bass. Seems very CD dependant for me. Overall, I'm quite happy and I am running McIntosh power with ML Vantages, which are not known for the stongest bass. I'm wondering if you have enough runnin time (breakin)?... And in the end, I'm also interested in this Burson Buffer. Hope to hear about it soon.
I do remember you comparing the 840C to a Nak cassette deck. Maybe that deck just has less upper end extension and so it sounds like the 840C is underpowered in the bass department. In any event, I hope you figure out your conundrm and a great fix, if that's what is needed.
