Are there any albums you consider perfect?
Tull's first album "This Was" is the closest to perfect IMHO, but Aqualung might qualify also."A Salty Dog" and "Broken Barricades" by Procol Harum are worth consideration as perfect also.Also I'd have no qualms nominating "Magician's Birthday" - ... 
High Current SS amps with input impedance = 200K
This is primarily for the OHM 5s which have a somewhat difficult load, are only 87db efficient and the more juice, the merrier.Power requirement: 250w/ch minimum doubling into 4, high current.I'd like to stay under $2500 if possible for now.Also, ... 
High Current SS amps with input impedance = 200K
Tvad,Any SS Amp recommendations given all this? 
High Current SS amps with input impedance = 200K
My strategy will be to play it safe and go with a high current SS amp that doubles output into 4 and eve 2 ohms as much as possible and has a higher input impedance, along the lines of those I mention above. That will optimize electronic interface... 
High Current SS amps with input impedance = 200K
It does make sense to me optimize the electronic interface between components in a system to whatever extent possible, all other factors aside, to maximize inherent performance.The input impedance of my current Musical Fidelity A3CR amp is ~31K.I'... 
Ohm Walsh Micro Talls: who's actually heard 'em?
YEs, the consensus also seems to be that the higher ratio the better for optimal interfacing between amp and pre (sounds kinky), so who knows where a 10:1 minimum comes from? 
Ohm Walsh Micro Talls: who's actually heard 'em?
Rebbe,After some investigation, the ARC sp16 I use is also a candidate for you at least technically, though the cost may be a tad higher.Here are the specs:260 ohms Single Ended main; 20K ohms minimum (amplifier input) load and 1000 pF maximum cap... 
High Current SS amps with input impedance = 200K
Well, that's very different then.ARC's specs are the most detailed I've seen so far then in this regard, and my original question is a moot issue then I suppose..

""Emerson, Lake & Palmer" does not have a lighter cut.""Lucky Man"Very good + a hit, but light/commercial by ELP standards. 
High Current SS amps with input impedance = 200K
NEwbee, you may be right.Here are the specs from the arc site:OUTPUT IMPEDANCE: 260 ohms Single Ended main; 20K ohms minimum load and 1000 pF maximum capacitance. Outputs (3): 2 main, 1 record (Single Ended RCA connectors). I'm not sure how to int... 
Ohm Walsh Micro Talls: who's actually heard 'em?
So for example, my case, with the ARC sp16 premap output impedance being 20K ohm, I would want an amp in the 200K input impedance range (my A3CR is only 31K). Also, interconnects factor into the equation in regards to impedance loads presented to ... 
Ohm Walsh Micro Talls: who's actually heard 'em?
Here's an interesting thread on the impedance matching issue:http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1227661419&openflup&12&4#12The consensus here seems to be a 10:1 amp input/pre-amp out ratio is a good target. Also that act... 
Ohm Walsh Micro Talls: who's actually heard 'em?
Tvad,One other question. Certainly a low pre-amp output impedance seems to make it easier to match more amplifier input impedances, but I wonder is it the absolute value of the preamp output impedance, or the ratio or magnitude of amp input impeda... 
Ohm Walsh Micro Talls: who's actually heard 'em?
Tvad,Have you found the better clarity and control extends into the upper frequency ranges as well?Any downsides that you can identify to go along with the benefits?This is something I'd really like to test out in my system. 
Are there any albums you consider perfect?
"Yeah, I love "Brain Salad Surgery", but Benny the Bouncer blows it for me. Otherwise, it's a perfect LP, IMO."Point taken, but even BTB is fine in the context of the rest of the album.ELP liked to lighten up most of their albums with at least one...
