« on: 20 Apr 2006, 10:06 pm »
Just a reminder to AudioCircle members that the best way to keep up to date on the latest news and products from Mapletree Audio Design is to  read the Branches newsletter which you can download from the web site. If you wish to be notified of future issues just email to with 'subscribe to Branches' in the subject field. cover pages.jpg" height=300 width=688>

Here is what you will find:

Issue 1: History of the Ear+ family of headphone amplifiers and some tips for modifying your Ear+, report on a 12/6SN7 tube  rolling/listening test with the Ultra 4A SE, and  a tour of special 100th anniversary editions of the Octal 6 and Ear+.

Issue 2: Designing high performance volume controls, more tube rolling with the Ultra 4A using 9-pin adaptors, and a tour of the new Stealth 60 power amp.

Issue 3: Designing high performance balance controls, an introduction to the new Ear++ III, and a special section on tools and tips.

Issue 4: In press. A special issue on getting more out of your collection of power amps and speaker systems—high level crossover plans for bi-amping with separate speaker systems, implementing a subwoofer, and resurecting the Hafler ambience recovery setup. And, of course, a new product to help you do all this: the Process 7.
