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!

Sorry, I guess I can’t.. For some people this could be a welcome contribution. You Mentioned the ragged top end. A Preamp could contribute to this, but the tweeter could also be part of it. So I was only trying to be helpful.  I won't respond about your speaker again.
It might be helpful if you explained why you are replacing equipment.  Are you trying to achieve a specific sonic goal?
Not happy with my current SAE A202 amp - lacks staging depth, imaging is sometimes confused, it's a little thin, and not quite as musical as I'd hope.  Though it drives the DQ10s well enough, I think there's room for improvement, hence identifying it as the weak link in the system and replacing it with the 4BST. See my post here:

I listen to a wide variety of source material, mostly Jazz, Classical, traditional Rock and some pop, so I'm more or less all over the map.

Here are a few I have on the radar, in no specific order of preference, but need input from you guys who have more experience based on my equipment since I don't know what characteristics or advantages each may have over my C28:

Cary SLP-50
Threshold FET1
Krell KSL
BAT VK3
Conrad Johnson PV14L
McCormack Deluxe Line Drive
Tortuga LDRx

Other 'non-mainstream' suggestions have been:
Bottlehead
Prometheus TVC Reference


It’ll be here tomorrow. I’ll probably be sitting on the steps waiting for the UPS truck to pull up.

Another question to add to the list, is whether I ought to be looking for a Preamp with balanced outputs, since the amp supports that.
