I finally bought my own a pair of Magnepan 2.7QRs over 20 years ago, and now drive them with a Gamut D200 Mk 3 fed by a Sonic Frontiers SFL-2 Signature pre-amp. Sources are a Burmester 089 CD player and Simon Yorke S7 record player with Graham Phantom arm.

The Gamut is a single MOSFET per channel design with 200W/ch into 8 ohms, 400W/ch into 4 ohms. With high current capability it is a match made in heaven for the Maggies. The speaker cables are Kimber 12TC.

The one downside of the Maggie design is the cheap stands that allow it to wobble slightly. While there are proven cures like Myestands and the awesome Magnestands, these require expensive shipping if you live outside N. America.

Last year I found a great solution that does not require any mods to the speakers as such but effectively decouples them from the room, improving bass and transparency, and all but eliminating room resonances. This is the Townshend Audio Seismic Platform from the UK, which Max Townshend will custom make to suit the footprint of your speakers stands.

I use the 2.7s with an REL S3 subwoofer, also on a Seismic Platform, and the result is simply awesome with lifelike holographic imaging underpinned by subtle deep bass when required. Although I visit the Munich High-End Show every year I have yet to hear a system less that 10 times more expensive that is better in any meaningful way. Bang for your buck; you bet!

Comment on Magnepan Incorporated—A Tiny Giant by Ross Cauldwell Mon, 31 Dec 2018 20:50:21 +0000 I have been an audio enthusiast since my college days in 1970. I heard the 6-panel Magneplanar Tympani’s around 1971)and never forgot the amazing sound, but I had to settle for large Advents, which I still have today. A year ago, I had the opportunity to hear the SMG’s and the owner sold them to me. I am again amazed at how good these sound; everyone who listens to them is amazed as well. I use these in a small 4-season sunroom, so despite the less that ideal acoustics, the sound is awesome.

These are easily driven by a used Yamaha HTR-5960 receiver (100 RMS @ 8-ohms) which I acquired from an electronics store (sounds equally well with Yamaha HTR-5760). I know these are 4-ohm speakers and purposely chose these receivers. The lowest bass register is supplemented by a Polk Audio subwoofer. This is a relatively inexpensive setup that absolutely sounds terrific. Jazz, blues, vocals and country all sound crystal clear with an incredible presence and soundstage.

Comment on Droidisk – Playing music by John Reekie Wed, 19 Dec 2018 23:14:18 +0000 It appears that the Tidal UI in Volumio is there now but requires a paid subscription. At any rate, the BubbleUPnPServer install is the best approach as it will work with any DLNA renderer.

Comment on PiDisk – adding the music services by John Reekie Wed, 19 Dec 2018 18:53:44 +0000 Hi Jim, cool, glad it’s working for you 🙂 I thought the default setting for minimserver was for automatic startup, but at any rate you can enable it by running minimserver/bin/setup, selecting y then y.
Interesting that NTFS mounted automatically… True, Samba is not necessary if using rsync to load up files. I have an article on using Resilio Sync for that nearly ready to go, which is a nice way to do it.

Comment on PiDisk – adding the music services by Jim Hardy Mon, 17 Dec 2018 15:17:57 +0000 IT WORKS!!!

🙂 🙂 🙂 🙂

Thanks for much for this. Couple notes:

* I screwed up my fstab configuring Samba. Since I’ll be using rsync or similar for copying music to the drive, I backed out the changes and purged Samba. Seems an unnecessary step.

* Your instructions have bubbleserver set to start on boot, but not minimserver. Oversight?

* My USB is an old Western Digital “My Book” that I’ve had lying around the house for years. It’s NTFS. I figured I’d have to install drivers for it: but no, the Pi just mounted the USB automatically when I plugged it in! Pretty brilliant.
(I have a 3 B+)

This is fun. And so great to have the family room stereo back. Thanks again.

Comment on Magnepan Incorporated—A Tiny Giant by Reinhard Thu, 13 Dec 2018 15:12:31 +0000 Dear,
since a number of years I have a set of Magneplanar Speakers in my studio. In the last weeks the left channel speaker shows some problems, and I believe, that there are some contact problems or defective elements somewhere in the crossover network inside the unit. If you can send me a schematic of the crossover network this would be helpflu to bring back this speaker to his full function.
The Magneplanar speakers are more or less one of the few speakers who could compete with Quad or Manger. I would like to keep these as my reference speakers. I could not identify which model my Maggies are, there is a metal panel which indicates the serial numbers 116787 -L and 116787-R
hope you could identify these…
best regards

Comment on PiDisk – syncing the music library by John Reekie Tue, 11 Dec 2018 11:47:36 +0000 Hi Michael, the key file goes into the home directory of the user e.g. /home/droid/.ssh
So… these articles assume that you have a Mac with a library, but you don’t want to keep the Mac turned on all the time. Hence syncing the library to the Pi. The automatic nightly sync is useful if you update the library frequently but not essential, as you can manually update it. I’m looking into a different solution for library syncing that will work on Windows as well.
I’m not sure I understand the rest of your question. If you have a NAS already then things would probably be different. Some NAS devices will allow you to install a DLNA server or even minimserver, in which case you may not need the Pi at all. Another way to do it would be to use say Volumio and mount your NAS using the web interface. However then a. you have to use the web interface and b. it doesn’t seem to work very well with large libraries. The combination of things I’ve written here works well together.

Comment on PiDisk – adding the music services by John Reekie Tue, 11 Dec 2018 11:37:49 +0000 Hi Jim, the Pi did work fine 🙂

Comment on PiDisk – adding the music services by Jim Hardy Tue, 11 Dec 2018 03:01:52 +0000 Ok, thanks. I’ll be sending to my Chromecast Audio, and I know BubbleUpnP works (currently using it on my Win7 desktop), so I’ll stick with the initial instructions.

This is exciting! Although, literally 5 mins ago I clicked “purchase” on Amazon for my first Raspberry Pi — it’s disappointing to think I should have stopped here first and learned about an ODriod HC1. 🙂 I’ll go read that article now.
