Great thread. I'm hoping to hear more from other folks on the subject.
I was about to make an identical thread post. I searched and found this one.
Here's what I am thinking.
I was thinking of selling/trading in my Primaluna Dialogue HP Premium Integrated for a Dialogue Preamp and then pairing that with an NAD M22 or other top quality Class D. The heat from my Primaluna amp relegated it to the basement for summer and I'm wondering if the Primaluna Pre + Class D would be a year round solution. Lugging a 55 lb amp (after reboxing it up) for half the year is not ideal.
