An all Parasound system - Good idea?

Don't believe that if it costs more or has a more prestigious name it is necessarily better.  Different?  Certainly.  Better?  Matter of opinion.  I just invested in a Pass Labs X150.8 stereo amp, which cost significantly more than my A21 and my Bel Canto REF100M monos.  In addition to these three amps I own a pair of Jungson JA-50 80 watt class A monos.  Every one of these amps provide serious enjoyment, all at different price points and with differing technologies.  Which one is 'better'?  You tell me! I prefer the Pass in the bass region and at low level resolution and detail retrieval vs. the other amps.  But it is not as 'sexy' or 'regal' as the Jungsons.  I can and do live with all of them, and gladly. I don't believe in absolutes, nor do I believe if you spend more you necessarily find something you end up liking more.  In fact, I believe sometimes if you spend 'too much' (or 'more') you actually end up disappointed because your expectations are not met based on what you paid. 

Sorry, Bel Canto REF1000M monos. 

No absolutes in audio and I  respect everyone's opinion.  I've owned many components over the past 30 years. Nothing is as good as I have  now, based on my priorities and my ears. I could careless about the name or cost of a particular component. I have Monitor Audio speakers. They are not viewed as being high-end like Magico, Wilson, and a few other companies, but I have them anyway. My point is I never said anything about manufacturer or price determines what sounds good. I only said I didn't like the JC 2 and it's only my opinion.

Ricred, for you to describe the JC stuff as 2 dimensional, masks details(What??) and a big disappointment, there was something else at play.  It's not a case of different strokes for different folks.  Perhaps your speakers are a bad match for Halo gear, maybe you didn't break them in properly.  Your cables might be muffling things somewhat.  I know that I've cleaned all my cable connections and with deoxit and had the q-tips turn dark with carbon, and the sound improved afterward.   There had to be some other issue.

I mean, I guess one could prefer another brand, but not because the Halo stuff is 2 dimensional.

At the time I had the Parasound A21 amp and I'm describing what I heard after a couple of weeks. Initially I thought the JC 2 was fine, but after continuous listening I decided to sell it. Notice, nothing negative about the A21. 2nd point.. it's my opinion, my ears, and no one can tell me what I heard or what to think. 
My friend had 4 different amps recently: McIntosh, Absolare, Bricasti, and Rowland. The Absolare to my ears was on a different level. I prefer the Rowland over the McIntosh and Bricasti. I'm not afraid to tell my friend the Absolare to my ears was better than my Rowland. Don't want to argue about my opinion.
