Cetoole has ordered a number of extra boards and has addressed this in his latest post in the Headwize Marketplace. Also, Jeff Rossel has ordered a number of boards and will be offering kits on his GlassJarAudio website. |

I need to keep up better.. Thanks for the update. Oh, I put a price tag of ~$45 -- is that reasonable? I also upgrade the Mini3 v2 -- do you have an average cost of parts? JCD [Edited by JCD on 08-01-2007 at 06:52 PM.] |

The MHM has been added.. I tagged it with a cost of $165, is that correct? JCD |

It's more like $70 with Hammond case.
Around $75 with Hammond case, AC-DC wallwart and battery. [Edited by amb on 08-01-2007 at 10:07 PM.] |

oops.. does that mean I should be increasing the amount of the σ22? I currently have ~$80. Thanks for the update. JCD |

The σ22 will cost more than the σ11, but since it's not designed for any specific case, the cost is more uncertain. Typically a larger transformer is also used with the σ22, increasing the cost too. I'd say probably ~$120 with a large dose of variability. |

I added a link to both the Elliot and Raymond Audiopages websites -- figured that would be good enough. I didn't see any headphone amps on the PassLabs page. Regular speaker amps, but no headphone amps. As for Walt's page -- I think that should be included in another sticky of similar links. JCD |
| JCD Member Joined: Feb. 20, 2006 | Message [#93] posted on: 08-22-2007 04:25 PM CST (US). | | A thought occurred to me -- this "project" I've kept up has, in some ways, evolved to include projects of many skill levels and goals, and included non-amp projects as well. That's all fine. One area that never really blossomed was the "grading" idea. I thought maybe we could replace that real estate with a "difficulty level" for each project. That way, whenever a new member asks the inevitable "what's a good project for a noob", we can simply reference this list. Anyway, thought I'd throw it out there and see what folks think. If the idea seems like a good one, I'm hoping our more experienced members might be able to give the projects a grade == maybe a 1-10? or Beginner, Intermediate, Expert? Thanks. JCD |
| amb Headphone Council Joined: Apr. 1, 2004 | Message [#94] posted on: 08-22-2007 04:40 PM CST (US). | | It's a great idea, but 1-10 may be too fine-grained. 1-5 is probably much more useful. |

Can you provide cost to complete? and the difficulty level of the amp? and any other comments I should put on the list? JCD |

That looks more like a commerical product rather than a DIY.. or am I missing something? JCD |
