Not sure what to think


This weekend I spent A/B testing a new preamp. My system: OPPO 105 (I only  have CDs), Bryston 9B-SST amplifier, B&W 801 loudspeakers (circa 1980) no special cables, non-sound treated room. My current preamp is a Krell-KAV 250p recently serviced. I have always wanted to test a McIntosh preamp. My dad had McI equipment when I was growing up and recently visiting local stores with McI in their listening rooms blew me away (as would be expected in a vendor-setup room). I borrowed a McI C-49 to try out.

I spent 3 days putting different CDs in and out. Rock, jazz, classical, house. In rock, 80s rock, prog rock, anything I knew super well. I tried a few SACDs, too. I had to keep switching the cables so there was always about a minute or so going between the equipment. 

I wanted BADLY to hear a difference. I really did. Between the childhood nostalgia, the looks of the McI (yes, I know music is for listening, not watching what it comes out of), and the vendor visits, I was ready. I had to believe my "vintage" Krell would not stand up to a modern, much more expensive McI. I spent hours going back and forth and back and forth. I kept telling myself I would hear something different on the McI and I just did not. So many discs, keying in on different types of passages, focusing on the bass or the vocals or the mids. You name it, I was ready for that one tiny moment to say "drop the money on a McI and don't look back."

Alas, as much as I still have a passion for the McI for the non-auditory reasons above, for the moment I will be sticking with my Krell. I am not here to knock McI - I still love the thought of it, or any type of equipment that might upgrade my listening experience. I guess I should feel good that the Krell is still working and maybe something else will come along in my future. My sound producer friend suggested I spend the dollars on room treatments. :-)

I’m not sure if your experiment proves much more than what you've stated -- e.g., about solid state, low or high cost. or other extrapolations -- because it’s possible that the acoustics of your room are masking differences you might hear with a better treated room. It’s also possible that your speakers are not revealing the difference, but my money is on the room.

Only once I really dialed in my room could I start to hear differences between gear. I can tell differences between my class D hypex amp vs. my tube amp. vs. my class A amp vs. my class AB amp. I can hear the difference between tube changes in the amp or preamp. But all this only became possible when I measured and adjusted the room.

Mediocre acoustics is like putting a lot of ketchup on different meats; they all tend to taste the same.

I agree with room treatment and trying a tube preamp. Trying better cables might be good too.

I worked for the county's largest Krell dealer the combination of a tube preamp with a solid state amplifier was always amazing 

 

the Mac preamplifiers and amplifiers are not very transparent so I am not surprised you didn't hear a huge improvement

agree with the other posters I would definitely look at a tube preamplifier

 

the backert labs gear is the way I would go with

I too have some Bryston gear, including a 9B SST in the HT. That’s a very nice amp for digital. I agree about improving your digital front end - that’s where I would start.

Cables last - like after your first 100K. IMO.
