Replace C28 with... ?


In my previous thread regarding a power amp, some of you commented that replacing the McIntosh C28 preamp would make a huge difference. However, what was missing was any elaboration how why you made the recommendation, and with what to replace it.

So, let’s get down to it.
McIntosh C28
HiFiBerry DAC+ Pro (Yes, I know... sacrilege, but it’s all I’ve got for now)
Bryston 4BST
Dahlquist DQ10
Polk PSW650 sub

Need guidance from you guys on whether I ought to be looking at SS, Tube or even a Passive unit. Since I have some skill with a soldering iron, I'm not above entertaining the idea of a kit.

I’ve seen the Tortuga LDRx and that concept looks pretty interesting. My worry is that the DQ10s can be a bit aggressive on the high end with that ribbon tweeter, so I’d like to hear your thoughts.

Thanks again in advance!

It may or may not effect this thread, but the DQ10 does not have a ribbon.  To add one, someone would have to modify your crossover. I would assume that with  the comment about getting aggressive on top indicates that the piezo is there and not a ribbon.
Correct - my error, I mis-spoke - meant to say 'piezo'.  Back to the question at hand...
Disconnecting the piezo was a popular tweak back in the day when I owned the DQ 10. Give it a try!
The piezo can be modified or better yet,  replaced and the replacement modified.  Let me know if that is an interest.
