I am the recent second purchaser of a pair of MG1C speakers with a B&O system to initially power them. It is a three piece B&O with a Beomaster 6000, a Beogram 8002 with a brand new Soundsmith cartridge, and a Beocord 8004 tape deck. This comprised the system as purchased. It sounds terriffic, but I will upgrade the stereo components, as the B&O stuff is massive and requires a huge flat space. I will replace the amp with a Heathkit AP-1800 preamp, and a Heathkit AA-1800 amplifier. The AA-1800 could easily pump out 500 watts all day, but is very conservatively rated at 250 watts per channel into 8 ohms. These pieces were part of Heathkit’s Professional line, and cost like it. I’ve never heard a better sounding combination. The pre-amp is just as awesome as the power amp. The pre-amp’s versatility is simply amazing. So getting these hooked up to the Magneplannar’s will occur just as soon as I get them back from refurb! They should easily sound as new then, and thinking how good they sound now, I can’t wait to get them back.

I suppose I will totally rebuild the B&O’s and resell them. I’ve been restoring old or new electronics for more than 50 years, so you folks can imagine how good the rebuilt components will be! Former EE, ME, CS kind of person.

All the best – Don H.

You could look at the article https://www.hifizine.com/2018/12/syncing-a-music-library-to-a-droidisk-or-pidisk/ for a different approach to syncing a library.

Comment on Subwoofer Origami by John Reekie https://www.hifizine.com/2012/12/subwoofer-origami/comment-page-1/#comment-112599 Tue, 30 Apr 2019 16:47:18 +0000 http://www.hifizine.com/?p=4056#comment-112599 Hi, the nulls are roughly to the sides in all cases with the listener “underneath” the diagram. I think your suggestion will have a small effect on the bass response but only small.

I was wondering if you knew the effects on the N-frame subwoofer if one were to lengthen one of the sides of the subwoofer to the rear. In your diagram, I would be referring to the upper left side. I was thinking that while the front and rear won’t be totally symmetrical, the added ‘wing’ might take advantage of some of the ‘dead’ space behind the speaker and cut down a bit more on the open baffle cancellation without providing quite the resonance of a U frame in the rear. Also, what is the radiation pattern of the N frame? Is it from the ‘mouth’ of the ‘N’ or is it along the plane of the driver? I hope these questions make sense. Thanks

Comment on PiDisk – adding the music services by Didi https://www.hifizine.com/2016/06/pidisk-adding-music-services/comment-page-1/#comment-112597 Thu, 18 Apr 2019 20:19:05 +0000 http://www.hifizine.com/?p=10125#comment-112597 HI John,

Thank you very much for the great explanation for setting up an Minimserver. I am happy all the day. Great job. Good to understand as well for somebody who has no glue from Linux. The only what did not work was the implementation of the automatisation process you described at part 3.
The command you have written doesn’t work for me.

But anyhow. I am so impressed that such a small devices streams my music to my Linn DSM.

Greetings from the heart of Europe

Dietmar

Comment on How to stream TIDAL to the Raspberry Pi by John Reekie https://www.hifizine.com/2016/06/how-to-stream-tidal-to-the-raspberry-pi/comment-page-1/#comment-112596 Mon, 04 Mar 2019 04:25:08 +0000 http://www.hifizine.com/?p=10267#comment-112596 And to add another update, it does work on a Mac (having BubbleUPnPServer and Kazoo running on the same machine). I’ll add a note to the article about Windows.

I usually run it on the same SBC as my music server (minimserver). I tried opening up Windows firewall ports to enable Kazoo to “see” the OpenHome renderer from BubbleUPnPServer but had no success.

Comment on How to stream TIDAL to the Raspberry Pi by Chris H. https://www.hifizine.com/2016/06/how-to-stream-tidal-to-the-raspberry-pi/comment-page-1/#comment-112594 Sun, 03 Mar 2019 15:15:58 +0000 http://www.hifizine.com/?p=10267#comment-112594 Hi John. Here’s one more sign-post with updates, in case others want to do something similar. I was not satisfied with the solution of running BubbleUPnP server on a separate laptop, because that’s too many things to boot for playing music. So, yesterday I bought another raspberry pi and successfully set it up to run BubbleUpNp server. Basically, I installed Rasbpian lite and set it up for SSH (by adding a blank file call SSH in the boot folder) so I could use it without a monitor. Next, I SSH’d to it with Putty (from Windows) and followed the steps for installing BubbleUPnP on a Debian system that are on the Bubblesoft website. This involved installing Java and downloading and installing the bubbleupnp package. After that, I figured out the internal IP address for my new pi by looking at the device table in my router configuration. Finally, I used my laptop to browse to http://[raspberry pi address]:58050 and configured it as you described. So now, here’s what I’ve got:
1. A Raspberry Pi running Volumio, attached to my stereo system.
2. A second Raspberry Pi running Raspbian and BubbleUPnP, which is configured to set the Volumio renderer as an OpenHome point.
3. Linn Kazoo on my laptop as the control point.
I now can listen to Quobuz music and save favorites directly through the Kazoo app.
As an afterthought, once I learned how to install BubbleUPnP on a Raspberry Pi, it dawned on me that I probably could have just installed it on original one that’s running Volumio. I haven’t tried this yet, but a little more googling revealed that someone else has already created a third-party plug-in for BubbleUPnP on Volumio (though it isn’t officially sanctioned by the Volumio team–they want you to use myvolumio instead). So, I guess the takeaway is that it might be possible to run BubbleUPnP on the same device as the renderer, but I could find no information on how to run it on the same device as the control point. Thanks again for setting me on this path!

I don’t know if it’s the firewall, because I created a rule to allow all traffic to 58050, and it still did not work. I think it requires some kind of port forwarding back to the localhost, but that’s beyond my skill level. Maybe there’s no way to have the control point on the same device as the server. For now, I am using my other laptop to run BubbleUPnP, and my main laptop has Linn Kazoo. At least with this setup I can stream directly to my raspberry pi. Thanks again! I really appreciate this post.
