I've owned both of the preamps your colleague recommended and I doubt either one would be the equal of your current preamp. If you're interested at all in the Modwright units then look higher up the line. The BHK is not only discontinued but noisy and finnicky about tubes. As the reseller of most PS Audio trade-in gear I'm sure they have a warehouse full at this point. I would look at Backert and Linear Tube Audio.
Suggestions for a holographic preamp?
I'm looking to replacing my Herron Audio tube line stage with something else, not because of a problem with the sound, but for a few other reasons.
I do both digital and analog, and have a Herron Audio tube phono preamp. My power amp is an MSB S-200, which is awesome, and my speakers are Marten Parker Duos, which are wonderful for a deep, holographic soundstage that I like so much.
I listen mostly to rock and reggae, and I'm looking to keep the price under $10K US, and I'm fine with a used one as well.
I get the feeling that I will need a tube preamp to get that holographic sound, but perhaps there are some SS ones that do as good a job?
The fellow I work with at The Music Room suggested a ModWright LS-100 or a used PS Audio BHK preamp; I've researched and they both look like they'd fit the bill, but I'd like to hear your suggestions, too!
