Amp and preamp on same outlet?

Jim, what did I tell you before about trying to teach a pig to sing? ;^)

If Al is still following this thread he can do a better job of translating the info from page 22 of the owner manual than me.

Hi Jim,

I can't do that with any certainty, because as I see it the specs provided in the manual are both ambiguous and inconsistent.

First, output power into the various load impedances is specified as "each channel driven." I would normally expect output power ratings to be based on both channels being driven simultaneously, but as I alluded to earlier the specified maximum input power of 6000 watts seems (given that this is not a class D amp) to be too low to be consistent with the specified output into 2 ohms of 2800 watts, if the 2800 watts (or anything close to that amount) is provided by both channels simultaneously. So perhaps "each channel driven" means "one channel driven," rather than "both channels driven."

Second, the specified maximum power consumption of 6000 watts is identical to the spec for the FPB 750Mc monoblock amp (for which specs are provided on the next page of the manual), with that amp having just slightly higher output power ratings. Same goes for the other two monoblock amps in the FPB series and their stereo counterparts. Yet the power consumption numbers for standby and idle conditions differ between the stereo amps and their monoblock counterparts by approximately a factor of two in most cases, as might be expected.

So I don't know how to reconcile all of that, and it seems that all of these numbers have to be taken with some grains of salt. And adding to the uncertainty is the point you raised earlier about inrush current, which of course is unspecified.

Best regards,

Reading back I see that the OP Audiolover718 says his system sounds great now - that's wonderful. Glad it worked out for you. Still would be curious to know what speakers you are using if you see this.

Interestingly (only to me perhaps), after switching to a moderately powered tube power amp (60 to 85 watts or so per side) I found that the lights no longer dimmed at loud passages like they did with my previous 100 watt pc high current SS amp.

I hear you Wolf_garcia. I love my Music Reference RM9 100 wpc tube amp. But here is the thing. It puts me at the 15th row of a night club's music scene which is pretty cool. The Krell however puts me in the 5th row up front. So much energy there. Now the back rows I have to admit were better in the younger days ......for checking out all the chicks. Also no lights dimming when I turn it on (20 amp circuit) - I do close my eyes when the utility bill comes in though. Still I am able to listen all day and night if I wish and not have to strip down like I had to do with the OTL 195's. Again in my younger days this could lead to good things. These days it leads to strange looks and questions.

@audiolabyrinth

Not sure why you had a problem with 20 amp and your Krell amp. As you know the Krell 600 is cruising with B&W Matrix 800 which were Dan D'Agostino's personal speakers in this amp era. Any thoughts of having to tweak the power panel (non-existent). The Apogees mentioned on this thread - Apples to Oranges. Much greater amp load, and load on the house power. I guess I can maybe understand why an Apogee owner would search for power tweaks with those speakers. Does make me wonder what kind of bad ass speakers you must own? Maybe on another thread we can discuss this.

fwiw - I sold a classe ca300 to an Apogee owner. He used it on them with those autoformers....

Happy Listening.

Jea48, Hi, believe it or not, I have $11,500.00 into my amp!, it is totally new out side nearly everything inside, however, I was shocked myself, I have no idea Jim as to why Krell used a inter power 15 amp wall plug on this captive power cord!, unless they were tring to save money,LOL!, the inter power I have is brass, ok sound for what it is, but you can see as to why going to a high end wall plug like the furutech FI-50 Rhodium that is overly built 20 amp would be a good idea, Jim, I talked to chris vanhause of vh-audio, he sells the 30 amp wall plug version of the FI-50, his words- why would you buy this?, the 30 amp only has a little bigger contact surface area inside, the side ways blade is for child safty or people that would try to plug this type of wall plug to a normal fitted wall outlet, their is NO difference in each one for sound or power handling., end quote, chris also told me he does not list the 30 amp wall plug version on his site, no need, the version he sales is cheaper and can handle a load that I have here for sure, that said, I believe krell also used the inter power 15 amp plug on my captive power cord because this will not make any difference useing a 30 amp circuit, I know you dont believe that Jim, however, I have no issues!, the wall plug does not in any way change temperture driving the amp hard, it stays cold all the time jim, like I said, I am only conterplating on this furutech FI-50M for sound purposses only because I have the matching wpo's-wall power outlet's, thankyou jim, I am reading into what you are posting, I do not disagree with you, but I am saying I have NO issues here with what I have set-up, I constanly check, cheers.

Thanks Al for your response to my post above.
