I’m wondering about this post of yours regarding the firmware version of the bhk 300. I have recently bought a pair and they have started to randomly go into protection mode. Sometimes while listening but at other times even just sitting idle.
As per your manual, it could be due to low input impedance, which I took to mean the preamp. I have since removed the pre (an old Nagra Tube Preamp) from the system and running off the dsjr since yesterday… Protection mode hasn’t since happened, but since it was unpredictable, I’m wondering if that was the solution or will it rear it’s head again.
How do I check to see if I have the latest firmware? Will an update solve my problem?
Well, impedance problems are referring to speaker impedance, not preamplifier. Sorry for the confusion.
It could be the preamp is spitting out spurious blips that set the protection in motion. I would just keep an eye on it. Seems like you’ve narrowed it down.
I don’t think an update would help since I don’t believe it had anything to do with that. I’d have to check with our service folks to be sure, but that won’t happen until Monday when folks are back to work.
Have you ever owned McIntosh amps? If not, I strongly encourage you to go demo them. As they do have a “signature” sound that many refer to. I would say it’s a little more on the “wet” side, not unnatural sounding, but more lively. Having owned McIntosh amps, and then the BHK’s, I would not revert back to McIntosh. But that’s just my preference for how I like to hear my audio.
I would also add that’s not quite an apples to apples comparison, as the power difference is going to naturally create more sonic headroom with the 1.2kw’s; which you may or may not notice, depending on how hard you drive the Maggie’s.
I’d also throw caution to the wind, it would not shock me one bit to see a revamped BHK 300 and a more powerful version, possible BHK 600. Point being, you may want to lob a couple inquisitive questions around that, especially if you like the sonic signature of the BHKs.
I owned BHK 300’s for two years. I owned Parasound JC-1s prior to the BHKs. Both are very good amps with subtle differences. When comparing amps absolutes just don’t work. System synergy is a giant influencer in a given amps performance.
That said, prior to covid lockdown I had a demo MC462 and C2700 that I was comparing side by side with the 300’s and a BHK pre. I ended up having the demo units for over two months because my dealer was closed so I speak with authority. Hands down, the MAC gear was the clear winner, simply a more effortless and natural presentation. I would have been quite happy to keep the MC462 since it is a fantastic stereo amp. However, I ordered MC611’s to go with the C2700 and couldn’t be happier.
I was at my dealers yesterday picking up a few demo pairs of speaker cables to try out, anyway he had a pair of JC1+ wired up to a pair of Magico A5’s (Mac C-1100T pre) it sounded ridiculously good, the JC 1’s just “manhandled” the speakers (88db/4 ohm nominal)
I’m running Accuphase amps at the moment but if I had the urge to change, the new JC 1’s, as well as the BHK’s would be on my demo list, along with Bryston 4B3 x 2
The Parasound’s were quiet, powerful and detailed, provided big soundstage width and slam, maybe not as “sweet” on the top as some (very costly) solid state amps or the BHK’s with the tube stage
Possibly more burn it would open up the top a little more!
Don’t get me wrong…I’m in no hurry at all to trade out of the Accuphase amps (P4200 x 2) I absolutely adore them and yes, as you referenced, the build quality is top at the top of the food chain! If their A class amps were in my budget realm, that would be the direction I would go in the future, no question
If I do change down the road, the JC 1’s really surprised me, they were much more “musical” (sry hate to throw out that wide ranging audiophile cliché) than the previous version but they still had that slam
I should have a dealer demo JC1+ pair soon to try for a month or so. Aesthetix Janus Signature and Maggie’s 20.7 with JL Audio F113v2 subs. PSA DS DAC and DSMP is my current set up. All powered by a P20 pair( expect for subs wall direct ).
