Living room system: class A or AB amps?

robert1976,

     As you know, you have very high quality speakers that deserve a high quality amp,or better yet, a pair of monoblock amps to drive them.  A pair of Gryphon class A monoblock amps controlled by a Pandora preamp are very likely to be a very good match for your speakers. 
     Each amp, however, consumes 700 watts to operate at idle and up to 2,650 watts during normal operation, which is roughly equivalent in electrical consumption of 1-4 high powered hair dryers.  Due to class A amp output transistors being run with constant bias, both of the large Gryphon monoblocks will very likely provide enough combined excess heat to significantly raise the temperature of your tropical climate room. 
      Given your requirements for very high quality amplification for very high quality speakers, that do not produce large quantities of excess heat and that can economically remain powered on in an optimum operational condition on a 24/7 basis,  I suggest you may want to at least audition a pair of very high quality Merrill Audio Element 118 class D monoblocks, in your room and system, before deciding to purchase any other amps.     
     Attached below are links to a professional review and followup article about these exceptional, unique and expensive amps:

" Class ?
That should determine little or nada.
Put some powered desktops on the TV and buy what amp favors the speakers most."

Hello fuzztone,
     I agree, amp type is not relevant when selecting an amp based on sound quality, however, it definitely becomes very relevant when  selecting an amp based on additional amp qualities such as electrical efficiency, size, weight and a low operating temperature. 
     Who knows?  I guess it might even be technically possible that someone, somewhere, who lives in a tropical climate, has high quality speakers and may even be an active Audiogon member,  might even have the shear audacity to be searching for The Friggin Holy Grail of Amps, which has the highly unusual combination of amp qualities of having excellent sound quality, being highly electrically efficient ,being light in weight. small in size while also constantly operating at a safe and moderate operating temperature regardless of the speakers' reproduced frequency and its correspondingly difficult impedance level presented to the amp.
     I believe we both agree that the possibility of an individual actually searching for such a highly proficient audio amp would be, at least theoretically, a discrete possibility.  Based on your post comments of "Class ?  That should determine little or nada.", however, it's obvious you lack even a basic understanding of how and why class D amp type technology generally, and the class D technology contained within the Merrill Audio Element 118 monoblock amps specifically,  represent such a useful, important, relevant and elegant solution to robert1976's amp search.
     As to your other brief post comment: "Put some powered desktops on the TV and buy what amp favors the speakers most."
     To be fair, however, I must also admit that I also lack a basic understanding, or even a clue, about what the heck this statement even means.

robert1976: "Did you just call your fellow forum contributors "schmucks"?"

Hello robert1976,

     I believe he actually called his fellow Audiogon members "schnucks".

     According to The Official 2020 Audiogon Forum Discussion Rulebook, often informally referred to as "The Bible", it unequivocally states the following:

     "If an Audiogon member calls another official member a derisive name but misspells that derisive name, for example intending to call another member a "schmuck" but misspelling it on a post as "schnuck", then it is not only officially permitted by Audiogon for fellow members to refer to this mentally challenged member by numerous similarly derisive names without penalty for a period of 1 year, it is in fact highly encouraged.               Furthermore, if the offending misspelling member is a repeat offender, such as our especially dimwitted member bigdaddy2, then members shall feel free to strike down upon thee with great vengeance and furious anger those that attempt to poison and repeatedly misspell the English language.
     According to a recent statement from the author of The Official 2020 Audiogon Forum Discussion Rulebook, Samuel L. Jackson, "our rulebook committee has just unanimously decided that fatdaddy2's misspelling of 'schmuck' as 'schnuck' represents such a major mental malfunction and high degree of schmuckery, that, beginning with the 2021 edition of our Official Audiogon Forum Discussion Rulebook's Supplemental Dictionary, we will be placing a picture of fatdaddy2 as an example in the dictionary's entry for the word 'schmuck'. "

Thank you,
