HeadRoom 9-V Micro Amp & DAC Stack/ SPECIAL OFFER!

hey Jorge, what's up with this 2007 module? I thought the last upgrade was 2006. can you tell us more about it if it is an upgrade over the 2006 module? or did you mean 2006? has there been any thoughts at HeadRoom to offer a module upgrade for the 2006 MicroAmp?

Interested in the Stack

Hi Jorge, I am interested and actually just now sent a mail to sales@headphone.com. My main question is whats the difference between this 2006 model and the new model. Can I get the manual for these. Also, in your site I find that there is a Micro Amp and a Micro Portable amp. But, the dimensions of these 2 seems to be the same. So, what is the difference between them.

The 07 Micro amp requires wal-wart to power and has no battery option. The new Micro Portable has a built in lithium rechargeable battery and an optional DAC in the same casing(not separate components).

Thanks mate. Would this difference affect the sound quality, if so, by how much. Also, wouldnt battery provide a better noise free current source than the wall wart.

The Portable Micro is about the equivalent of the 06 Micro stack maybe slightly less SQ but almost negligable. Thus it retails for the same. In comparison to the 07 Micro Stack(the non-portable ones) the SQ in these is significantly better partly due to completely new components and class A biasing such. The Micro's have the same circuit designs as the Home modules and Home DACs(I think) I know the Amps are the same not sure about the DACs. The Ultra Micros use the same components as the Max Modules, but are almost twice as expensive. Please note that just because the new micros have essentially the same electronics as the Home and Max amps doesn't mean that they have equal sound quality. The Home and Max amps have significantly upgraded power supplies as well as fully decoupled dual mono signal paths on higher quality boards. The Micros are no slouches though trust me I have the new Micro and Micro DAC and they're an excellent pair.

Also while the Portable might have a slightly cleaner noise floor due to the battery power the Micro Stack is plenty clean and I don't really hear noise until the volume nob is at least twice as high as my ears could take, and that's with IEMs too...with the Grado's there is no noise.

Hi Jorge,

First off I want to start by saying I love my Micro DAC. It is very open and transparent and warm and full sounding. It's the first portable DAC good enough to replace my iBasso D1.

We had several emails exchanged on 2/28, and I mentioned I wanted to order on the 29th to order before the 12 noon cutoff. You were busy but emailed me about 10am, so I called to order at 11am on the 29th when I woke up (my sleep apnea is killing my days), for delivery on the 1st. I didn't get to speak to you, so someone else helped me. I mentioned I was from Head-Fi.

I thought I was the first person to take advantage of the 2/28/08 sale, but I misread your post and when I looked at my CC statement online I didn't get the 15% off because I didn't buy a "pair". Oops, my fault, but 15% off both means I would have saved $89.70, and I would have done the pair for an extra $210 IF I had caught the mistake.

I also paid what I think was full price ($88) for the Microstack bag and Microstrap player platform, when I asked for the B-stock MicroBag that was $20 off. I somehow skimmed over the fact that I could have bought all three items with the pair, for $59. I have 600 threads I am subscribed to, and I had to learn to speed read, albeit poorly.

The price you offered on the 2/28/08 sale would have been $607.30 for everything, with over night shipping. I paid $427, and I didn't buy the amp or the extender strap that I could have had for ONLY $180.30 more!

I know my failure to read the details meant I missed out on all the savings, (and I am enjoying my DAC, bag and strap) but is there some way I could get the rest of the "package" for the $180.30 + cost of std shipping?

Thanks,

Larry G.

Thanks JorgeC,

I was the one who messed up by not reading the fine details, so I appreciate the quick email response taking care of the rest of the order.

That's great customer service!

Thanks Jorge for the manual. Did quite some research and decided that your desktop portable seems the perfect choice for me. Now, I better start saving a little more for that.
