Stevecham< "not to mention a much better current capacity doubling down to 2 Ohms. Parasound gear is not rated at 2 Ohms. If you don't need this current capability then Parasound may well fit your needs."
The current ability of the Parasound and heat dissapation is one of the main reasons to get the Parasound.
You also certainly can't compare the old lower tier Parasound designs to the new Halo stuff. They are completely different animals.
Comparisons
Krell: 750va Transformer
Parasound: 1.2 kva Transformer
Krell: 55,000 UF power supply filter capacitance
Parasound: 100,000 UF power supply filter capacitance
Krell: weight 36lbs
Parasound: combined weight 75lbs (The power transformer alone weighs as much as the Krell integrated)
Krell: Current ?
Parasound: 60 peak amperes per channel
Krell: Get's hot under normal listening conditions
Parasound: Runs relatively cool even when driven hard
The Krell is not rated for 2 ohm use either, not on their website, and not in the manual (and it certainly won't "double" it's current capacity at 2ohms, if it could it would weigh about 100+lbs), but I'd be willing to bet money in a 2 ohm torture test that the Krell would give up the ghost MUCH sooner. It's just physics. A much larger power supply, and much larger heatsinks will deliver more power (current)and dissapate more heat under any given load.
I'm not saying that the Krell isn't a great product. It is very attractive, has a good build quality and performs reasonably well for a $2500 integrated, but it still is just a somewhat compact integrated amp. I'm sure it is very enjoyable to listen to. This is still just the lowest model in the Krell line though.
In the back of my mind sometimes I think that all this crazy system with all it's complexity, variables, and cost might just be simpler and better served with just an integrated such as the Krell or Creek Destiny, and a player and pair of speakers... Then I sit down a listen to a new CD I picked up and realise why I do all this. It's probably the single most enjoyable thing I have in my life to be able to hear music like I'm in the studio with the artists. There isn't an integrated that can yet do that.
