ok, you got my attention, Aplhifi, what do you mean about the above statement, DSD-S Dac will help you realize your dream about removing the pre-amp from the rack?, please specify the brand and model if you are talking about a Dac that can run direct to amplification that sounds very good to you?
It is this one here that can drive any power amp direct - DSD-S DAC
Well, not exactly a dream, but a wish that Matt has expressed many times on this/his thread. :-)
Best,
