What qualities stand out in really good solid state preamps?


Recently I posted on the Herron HL-1, asking people what they thought, how it compared, etc. It's been sold and that's ok. The search continues. 

But it raises a question I'd like to ask folks:

What attributes do you look for in a good solid state preamp?

Some qualities — quietness, durability, seem pretty obvious.

But what other criteria do you use to differentiate between solid state preamps?

How can they differ and what matters to you?

Please let me know!

P.S. As I've looked around, I've begun to learn more about some of the legendary preamps — made by companies such as Threshold, Ayre, Bryston, Pass, Apt-Holman, and others. It's good to have these names as references, but it would be even more useful if I knew what these brands conveyed, sonically. I've played with the idea of getting a newer Schiit preamp and then I wonder -- what if there's a "classic" preamp out there, used? What would it deliver that was worth searching for?

Sound Qualities: the majority of SS amps and preamps were/are designed to change nothing audibly.

People hear differences, individual opinions or a general consensus?

Take your time, research, read, consider warranty and later service, maker's longevity, ......

 

@hilde45 Have you ever considered a hybrid preamp? I just bought a PS Audio BHK Signature preamp and it has a couple of 12au7’s for the input and mosfet’s for the output. Only had it a couple of days, but I am really enjoying it so far.

 

It’s kind of interesting that Paul of PS Audio was dead set against tubes for a long time.We are talking about someone who led the charge for solid state for decades.

Now the story about how the late Bascom H. King (BHK) finally talked Paul into using "TUBES" on the input stage of his amplifiers, and then TUBES in his BHK preamplifier. Why Paul says, "because it sounds better". Now he agrees.

All tube or hybrid with tube in the preamp, how PS Audio -or how Linear Tube Audio does it is fun to explore and test out. Finding a suitable (new era) solid state preamp that sounds "natural", and does not break the bank, is fun and time consuming research project. Best of luck to all here in that hunt, enjoy! :)

 

@elliottbnewcombjr After reading your two posts I do not see any mention of sonic metrics. Your comment, "change nothing audibly" is all I see. After all your years in the hobby, you never compared one SS preamp to another and made any notes (even mental) about the differences between them? (Such as the ones listed by @audphile1 ) That surprises me based on your other posts. Then again, maybe you are just being transparent about the fact that, for you, there’s nothing to be noticed.

I’m not asking for buying advice in my OP, but thank you for your thoughts.

"But as was said above, sometimes it’s nice to hear what the rest of the chain is doing, minus the preamp."

Have you ever considered a passive preamp?
