The Spirit is a name of portable amp from mSEED labs which is known by their former FAITH amp. You can find this Spirit amp on eBay, their own site or ALO site to purchase. I bought this from their site at $148 include international shipping charge.

This looks like an ordinal portable amp at first glance, but reading on the brochure I found some interesting points. First, this amp emphasis on musicality, I like this statement.
I also noticed this amp provide unity gain as a low-gain mode. I have been using Tomahawk for almost half year and I found the unity gain is useful for IEMs as it keep background noise at lowest possible level.
In addition, this amp employs a BlackGate cap and Wima caps, it also employs unique JFETs. I am not quite sure about the technical details but I was told the use of JFETs improve smoothness of the sound.
My educational guess (and my sixth sense) has detected this amp would be a good match with my IEM setups.



I think the construction is so-so for the price. This comes with Alkaline Battery but I have replaced it with Maha 9.6V. External power supply adapter comes with the package as a replaceable rear-panel.(AC adapter is not included)
here are my setups for iMod 4G and nano.



This is an early sound impression for the first 10 hours. I use RWA iMod and triple.fi 10 pro.
I have listen to Jazz, early music, female vocals, new age music, electronica and some rock music.
The sound is of fairly smooth, full and liquid as I expected. Vocals and human voices are not harsh and I found some unique sweetness on the edge of sound but I can not well verbalize for this.. Instruments timbre is nice as well, especially for violins and pianos.
At the same time, the sound is also highly articulate and powerful than I thought. Bass is tight and impact-full, higher register is clear and crisp.
This is also a good match with HD25 with high-gain mode. I think the downside is width of soundstage, though not so bad.
It is somewhat premature to compare with other amps at this moment, but I have a good feeling so far. IMO, this is well worth for the money.

I like to listen to classic chamber music with this amp, this is engaging. As the name imply, I feel the spirit of the music.

Make sure you burn that amp in. Black gate caps take a long time to burn in, say 200 hours?
Edit: Make that at least 400 hours. I was looking at the specs and it's a 2200uF cap. Huge!

I have a Spirit that mSeed labs loaned me to review. I broke it in for 200 hours. I will be writing up my review very soon, but fully broken in I can tell you it is a VERY good sounding amp.

Yeah, this is an unique amp, I have a TTVJ Millett hybrid portable also and IMO Spirit sounds similar to that. That is to say, tuby.

Skylab,
Do you think that Spirit is a good a sTomahawk to feed HD600/650?

I can't really answer that question. They sound different.
