Y'know, one thing we may have overlooked... the Bryston is the PRO model. Is it possible that a passive might actually work with this amp?

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!

Well, fellas, I just took delivery of a 4BST Pro in a solid 8+/10 condition with 5 years left on the warranty. Though I'm sure the C28 can be improved upon, in only an hour's time with the new amp I can already hear a decided change over the SAE. Instruments are more 'articulate' Imaging is more precise. Staging is (surprisingly) both higher and deeper. I can't wait to see what a new preamp will reveal. Though many have admonished me to look at a tube preamp, the diminishing availablility of 1940's technology worries me (i.e., ten years from now when the tubes need to be replaced there won't be any or they'll be a fortune), so I'm inclined to look at a SS unit. Keep those cards and letters comin'. Thanks! |
When I say "old school", I really don’t mean anything negative about it. The circuits are all good. What I’m really saying is that you’ll want to replace all the electrolytic capacitors - they do dry out. The Krell KSL is from 1992!! Suggestions would be based on what you feel you are missing. Do you feel like you are missing bass punch/weight and low midbass body? Or maybe bass is okay, but you’re missing resolution. If I had the HiFiBerry, I think my first thought would be to go after the BAT VK3i there’s one for $899. That would give me the bass/body. The BAT stuff has extremely good bass, but some find it lackluster in the high frequency detail and excitement. You could always start experimenting with tube choices. New tubes are still being made and the industry is not going anywhere. Otherwise, there’s a Krell KAV-250p for $725. This will probably give you more resolution, but you’ll want to replace all the electrolytic caps. Maybe look into Conrad Johnson to see what the general sound signature is like (I don't know anything about it) The McIntosh stuff is generally very laid back and may feel like you are missing resolution. Since you like where the Bryston took you (with more articulate instruments, etc.), you may want to lean towards Krell (or that Conrad Johnson). What’s your budget for preamp? |
Budget is roughly $1000, perhaps a little more depending on the opportunity, but less is better if I can find something great (read: non 'mainstream') or a 'deal' and save money. I'm only spending that much, because my hope is to sell the C28 when I find something I'll be happy with. On the upper end, I have my eye on a Krell KRC-3. It's more than I wanted to spend, but hopefully I won't have to do this again for many years. Besides, if I were to get something less expensive in the $800-ish range and have to re-cap it, I'm up in that price range anyway. Then, on the lower end, the Threshold is in the $500-ish range. Good to know that tube are still being made. I had visions of spending lots of money for a paperweight if tubes were no longer available. Narrowing it down to a handful, prices all over the map: Krell KRC-3 Conrad Johnson PV14L BAT VK3 Promitheus Reference TVC (not 'mainstream') Threshold FET1 |
