Thaddeus Smith Posted July 17, 2013 Share Posted July 17, 2013 ha, no worries. agreed, running at 12 ohms will create a decrease in overall power, but at 100db efficiency (108db for the top end) and a listening distance of 7ft, I'm not sure it will even matter. so which is the greater evil? decreased power or decreased amp options?

Caio Ferrari Posted July 17, 2013 Share Posted July 17, 2013 You'll get a lot of advantages running with higher impedances: Higher damping factor, lower distortion, more power reserve to transients.... In fact, with 100dB of sensibility, lack of power isn't a issue at all. Running with 12 Ohm impedance was a great tip for you. Quote Link to comment Share on other sites More sharing options...
Thaddeus Smith Posted July 18, 2013 Share Posted July 18, 2013 Hell, if I'm going to be driving a 12 ohm load I might as well go with an older plan I mentioned to Carl. Upgrade my HT receiver to something with Audyssey XT32 technology to help better tame my sub (Denon AVR-X4000 looks pretty promising) and use my Denon 3808CI as a DAC/Pre/Amp in 2-channel mode. It's 130w, more than enough connectivity and I can relegate it to preamp duty in the future. It has Audyssey XT and should help with some of my potential room issues. At $1,600 MSRP back in 2008 it's certainly no slouch in component quality. K.I.S.S.? Quote Link to comment Share on other sites More sharing options...
Islander Posted July 18, 2013 Share Posted July 18, 2013 Did you forget the pro amps? IMHO, before you buy that exotic amps for home use, you have to be sure that you're going to listen some difference between all that exclusive components and that very large supply caps that suppose to provide a "unique sound experience" and all that adjectives that I really don´t understand. Here in Brazil we made a test with a (good) professional amp with 250W and a home use amp with 35W. Besides the power, the difference was the professional maker didn´t spend money buying that expensive connection and audiophile components. No one chose the side of the lighter home use amp. The difference was mainly about bass. The low frequencies ran away when I played the weaker amp. And I'm tanking about a simple bookshelf speakers. I know it wasn´t a scientific test but the difference against the weaker amp was clear for me. The Emotiva are the only home use amp I ever seen that worth the money. The price range is quite equal the pro range and the design is good for home use. The audiophile people have my respect but I just don´t listen the difference between a ordinary amp or cables and the audiophile ones. May be I don´t have a good room, my music source isn´t that good or my ears are not good enough to hear any difference. So, IMHO pay more for that stuff is like throw my money away. In making any comparison, it's best to have only a few differences between the things being compared, so you know just what is causing the difference between the things. The very large power output difference between a 35 Wpc amp and a 250 Wpc amp will be so easy to notice that it may be difficult to pick out other differences, like "does pro audio sound better than home audio?". The difference between 35 watts and 250 watts is nearly 9 dB. If you'd been able to find a good-quality 150-300 Wpc home audio amp, it would have been a much more meaningful comparison.

Caio Ferrari Posted July 18, 2013 Share Posted July 18, 2013 K.I.S.S.? Yes! Just build your speakers and listen how it sounds with your setup before buy new amps. Quote Link to comment Share on other sites More sharing options...
Caio Ferrari Posted July 18, 2013 Share Posted July 18, 2013 Sure I'll need a powerful home audio amp to make some decent comparison... But it was enough to see that a lot of people are talking no sense when they say power is not THAT important, all because home amps have great supply caps and a lot of stuff that guarantee a lot of power when is needed. I know, a home amp with a lot of power would perform better but how does it costs? Except Emotiva, probably is 3 times more expensive. Today I'm sure that it better pay for a lot of power coming from a pro amp instead of get a weak home amp... Quote Link to comment Share on other sites More sharing options...
