I love that little Micro Amp, sad to see them go away.

Is that why they've been on sale? They're being phased out? redface.gif

Small in a sense, but you would have to include the enormous power brick.  If the power supply were built into the same box, it might look more like an Asgard in total size.  Well, perhaps not that large, and certainly not as hot. :)

I still think their BUDA is one of the finest headphone amps out there.

Thanks! (Me too.)

Anyone know if I can use my Nuforce LPS-1 linear power supply with the Micro Amp?

Been searching for the right cable to use between the 2, but I don't want to burn the house down if I get it wrong.

Until very recently, I've never been able to find any specifications on this amp for output impedance (0.5 ohms) or max power at any specific impedance for any of the gain settings.  I've been using an O2 at work and an Asgard in my home.  Now it seems I've had a better amp all along with the Micro Amp.

 

I'd love to know what the maximum power is for 25Ω, 50Ω, 300Ω, 600Ω with the 3 gain settings.  The output voltage is simply listed as 10 Vrms, and my math skills are too rusty to attempt to work all of this out on my own based on the info that is provided.

 

I like the Micro too. No way I'm ever getting rid of that thing. I even liked it enough to upgrade it with the Astrodyne power supply. I did the 30 day trial (which probably is not offered anymore) when I had the Asgard and Fiio E9 and immediately sold the Asgard. I only had the Asgard 1 though.

 

The nice thing about my Micro is there such such thing (to me anyway) of bad synergy etc. It sounds good with everything. It also managed to not sound cold/analytical and yet not warm. It's a bit weird to describe. My Magni for whatever reason sounds thin and bright with the Q701 somewhat. Don't ask me how.

 

With the Micro going away soon I wonder if there is anything that sounds 99% identical to it. Yeah I know it's transparent and all that, but it doesn't sound like a clone of the Magni (or maybe O2?). It sounds smoother/fuller than the Magni I have, yet it's not a warm sounding amp to me at all. If so i'd probably hate it with the HD-650.

 

Can't say it enough, but my Q701 just isn't the same without the Headroom Micro. It's hard to describe because there's not really any sort of coloration coming from the amp itself.

 

Oh and of course it's almost as good as what source/DAC is attached to it.

 

Micro almost reminds me of an E9 on a ton of steroids with better extension at both ends and better detail and a clearer sound. They both use similar op-amps but don't really sound the same.

 

For years I wondered if the Micro had any similarities to the M-Stage at all? It would probably be a downgrade or side-grade. My idea was that the M-Stage sounded a bit darker/warmer.

I used a The Max Amp as a pre-amp for a Plinius SA-100 driving Magnepan 3.5Rs 1998-2003.  At the time I could not improve on the pre-amp function sound quality with anything twice the cost of The Max. One dealer brought out a $2500+ Plinius pre-amp and left with it because it was no better. 

I still have this The Max that was retired in 2005 and am sending it in for repairs after apparently too many years on the shelf.  It is clipping like crazy on anything but the very lowest volume.  Headroom tell me they are not producing any new product or making older models current, but that they still intend to keep designing new equipment.  I guess their business model does not meet with current times.  

Soon I will have the Bottlehead Mainline and will compare the two.  Assuming that is that Headroom have any repair parts they might need ... they have let me know they will do their best.

According to this (link), the Micro power supply is 9V, 1.66A. 

 

Even if you could reterminate the Nuforce LPS cable with the proper barrel, the output is 12 or 15V (selectable with a jumper inside). You would have to ask HeadRoom if it can handle a higher voltage than the supplied wallwart.

Thanks, but that is for the portable micro amp.  I'm using a desktop version that came with a larger, 15V brick.

Since I normally don't use my Nuforce Icon HDP for anything but a DAC now, I have practically no benefit from the bulky, linear power supply unit.  I was simply looking for a way to make use of this with an amp.  The setup I use now seems to have no noticeable noise, and the LPS-1 would just be overkill.

I *think* the micro runs on a dual +/-15 rail, while the LPS only provides one, so they are likely not compatible. 

 

There's always this for overkill... http://www.headphone.com/accessories/headroom-desktop-power-supply.php

I actually did find a slight improvement in the HDP (serving as dac) with the LPS, but it was pretty minor overall. In my setup though I've got the LPS serving triple duty as power for both the Icon speaker amp (driving my HE-6) and HDP, plus spdif bridge to feed the HDP.

Ah, yes, you are absolutely correct.  It has this info directly on the power supply when I pulled it out and took a look.  Too bad the BUDA isn't dirt cheap.  I'd love to try one.

Make 'em an offer. The worst they can say is no rolleyes.gif
