Alright guys, I'll try the E1  see if I am happy with it. If not, I'll just look for another amp.

The output at 32 ohms without significant distortion could be anywhere from 300 mW to a watt I'd guess, but we can't possibly know without measuring.


Sigh. Yea, just like back in school, theory and math never end up being the same as real life.

That's right ;)

 

Many tube amps even have higher output into higher impedance loads for example.

I really don't think you can put down other amplifiers until you have heard them, the CA Liquid Gold has only 35.000 uF of capacitance,and it's considered one of the very best SS amps available, I've heard it personally and it sounded stellar, though outside my price range. I don't expect to get the same SQ out of a 1400usd amp, but I know I'll get maybe 90% or more. I feel like you may be drinking the blue circle koolaid a bit too heavily.

. Thats peanuts if u see the capacity of my realtime meassured only 5,28watts into 50ohm..my amp has 650.000uF! Thats more then a hundreds time the capacity of an amp being offically 3times more powerfull... I wonder whats more important.. Only power or the means to use that power? (reserves in capacitance).. ..

Simple! To justify the price you are paying.  Come on bud!  You are smarter than that. ;) 

 

and Yes, I have personally listened to the Liquid Gold on both HE500 and the Abyss.  That's a great SS amp but personally, I think it's over priced.

^ lmao.  Just trying to get you to lay off koolaid a little bit but apparently you are beyond that point long ago.  Btw, I am very happy with my WA22 for the HD800, but not with 100% with HE500; that's no secret.  I bought it hoping it will be great with both but have found out that it's not possible.  Remember that I pay $180 for my Emo and IMO, the Emo is already more than 90% there compared to even CA Liquid Gold.  If your blue circle is as good as the LG, that will be great but I will never have a chance to find out nor I would bother to attempt.

What bothers me is your self contradiction.  You often say that power is not everything for an amp to drive the HE500, using your beloved 337 as evidence.  Now, you have been border-line bragging about your new amp with its gazillion uF though you yourself don't even fully understand how so much uF would benefit the amp's SQ but so strongly believe that it will do magic.  That's the koolaid I agreed that you need to lay off.  That's an honest and non malicious input from a fellow sharing the same hobby.  Take it whichever way you'd like...

Sure, big transformers and lots of capacitance don't hurt... But I guess we all know and agree that isn't the only thing an amp is about, right? I suppose it is pointless to discuss amp performance based on such stats.

 

And really, I don't think most of us are knowledgeable enough on amp construction to really discuss and debate that much over it? I mean, most of us are just speculating..

davidsh, yes for sure it doesn't hurt to have a lot of capacitance and big transformers but there's always a threshold beyond which it will become unnecessary and wasteful.  You don't need to fully know/understand amp design to comprehend these basic technical / electrical basics.  I have personally seen too many audio components overbuilt on purpose to somewhat justify their price tags with no benefits besides what the maker/builder want you to believe.  I am just pointing that possibility out to a fellow HFier who seems to believe in those aspects quite a bit.

.. i still believe watts are not the most important part of an amp to drive a headphone...... but i understand what u try to say about the coolaid...thanks for that!

..just see this as an explosion after waiting for almost an year and at last seeing the frigging amp getting delivered in 1,5 weeks time.. soon i will be quiet again...and back to my 'lots of power'  is foolish outbursts ;) 

ps..i just swallowed my be cool and relax pills...i can feel they are taking effect already ;)

When I was in the speaker biz we used big caps to get big bass out of big drivers

Not certain how lots of caps would be useful in the headphone world which by comparison is very very small

I love you guys. Unlike other threads you know how to disagree without drawing blood. But I think we may have gotten to Hifi, he's had a sex change operation and has fallen to taking drugs. Now he'll never sleep, he was down to 4 hours a night.

That's because at 8 or 4 Ohms you needs a lot of capacitance to form a low enough corner frequency with the reactance of the speakers as not to roll off the bass nor cause phase problems. Also one needs a good capacitor ($) to pass power without exhibiting nonlinear behavior. That's why one tries to direct couple circuits, especially the final stage that delivers the final blow to your headphones, could also be speakers.

If you don't get those #$%@in' pads, I'm-a cut you, man!!

 

I mean....

 

welcome back, Stan!  How was the Indian?  Seriously, I'm jealous.  When I lived closer to DC, we had Indian to beat the band.  Now, I gotta try to convince my wife she's gonna love it.

 

I think you missed most of HiFi's rants, as he seems to have come back, stoned, and edited them to what you see now.  Honestly, I couldn't follow most of it (nothing new there :D), but I was hoping you'd jump in with some EE-grounded rationality.  Ain't no EE, but I hear grounding is kinda important.
