adcom equipment.....

Sure, no problem.  Being that I've owned both Parasound and Adcom previously, I compared some of the specs of the 555SE and the Parasound 2250 V2.  They retail for about the same...

The Adcom has comparable SNR and better damping factor(900 to 150), better THD and better frequency response, which is down to 10 Hz vs a -3 db of 20 Hz for the Parasound.  The 555 also doesn't need a 2 ohm switch to be stable at 2 ohms.  I can't find cap values for the 2250, but comparing photos, the Adcom's at 60,000 micro farads seem quite large compared to the Parasound.

One more thing.  The 2250 achieves unity power at 1 volt, which is the typical max voltage output for receivers, but not preamps.  The Adcom achieves full power at 1.75 volts, which would give more range on the volume dial.

To be fair, the Parasound has more features, consumes less power at rest, and has 275 wpc on tap vs the 200 wpc for the 555.  The new improved Halo amps look much better for more money, though.

 I got the 6002 in yesterday. Two things stuck out immediately. First, I was right about the better damping factor helping out the bass response compared to my old tube amp. No surprise there, but I do like an accurate bass. Secondly, the amp has a harshness to it that I am hoping will go away with a few hours of use. In general, it is an honest sounding amp to my ears, so it would be worth using for the time being, until my Forte' amp is rebuilt. 

That's an interesting result, the harshness I mean.  I found it not harsh with Totem Rainmakers( a somewhat forward/open sounding speaker), but perhaps the Halo P5 had something to say about that.  Then too, my definition of harsh may be different than yours.  My cabling differs too, but let's not get into that!

I suppose it is a budget amp after all, you can only get so much SQ at the price point.  

4krow,
how is the ummp factor, I had one rebuilt (555) and its clear as hell but a little lacking in the bottom end.  im thinking that will go away at break in as well..

 Guys, both of you make good points. Mostly, I know that what I am hearing is really due more to the combination with my speakers than the amp itself. I am referring to the single driver speakers that I am using from Decware Audio. So many things I like about these drivers, 'but' there has always been a certain frequency that shouts (in the midrange). With tube equipment, it was tolerable, but now that SS has the floor, there is less forgiveness. After pointing that out, I am willing to say that this little amp is well worth the money. Like I said, the damping factor improved the bass to my ears, and overall, I find a good open presentation. The ummp factor can be had, but mostly at higher volumes. Maybe a bit more break in is to be considered. Only a few hours on the amp so far.
 I must point out one feature of the amp that is cool. It can be set to standby mode, and then if a signal is sensed, it will turn on. No need for a trigger, although that can be used as well. Small thing, but appreciated
 I will be moving on in a couple of months when the larger amp is rebuilt, and that is where I hang my hopes.
