Thinking how to efficiently make space for it.
^ This with what phone?
Good idea to seperate trasformer as much as possible, but I also have limited height on my table, so separating each amp with rack is a bit tough, although I actually really want to separate each amp with rack tray so to avoid scratches to the surface of the amp.
Btw, how's Master 8 handle high impedance phones like HD650, T1 or HD800?
Any report on that?
I don't have them, but just in case.

 

I have the Master-6 not the 8 but it handles my T1's superbly and I have not even balanced them yet. I will order a 4 pin XLR today and re-terminate next week. I will then report back.

Thanks. How do you compare T1 running on Master 6 (in SE) vs your WA6 SE?

post #363 of 866

I mostly use the TH900, D7000. The other phones in my sig worked just as well to my memory.

I haven't compared then to be honest but I would say they are on the same level but the T1's are not yet fully utilising the Master-6 and the Woo is only running single ended off the DAC which should mean its at an disadvantage compared to the Master-6.

I fully expect the T1's to go up at least a level once balanced. biggrin.gif

Im thinking im just gonna grab a Master 3 instead for use with the HE-6s, since then i know i wont be running out of power, and plus, when i do have space for speakers ill already have a top shelf amp for them :D

post #366 of 866

Oh, seriously, you want to drive HE-6 with 250W @ 8ohm? The website don't have data for 50/60 ohms though (obviously)?

 

Isn't that seriously overkill?  biggrin.gif 

Nevermind, let us know how it sound  wink.gif

Itll be somewhere around 30-35 watts (edit: this figure actually comes out closer to 40 watts, using the simple halfing power for every doubling of impedance) i figure that it could pump into the He-6s. But i havent heard a headphone amp that can power them as well as a good speaker amp can. Even a dual mono 4 board fully balanced B22 couldnt do it. So i figure i should be safe rather than sorry, and its convenience to double as an amazing speaker amp in the future is priceless.

 

I will be sure to ask kingwa about that gain though. the amps max voltage output is 58 volts RMS. this means that in order to need 30db of gain to hit max output your input would have to be .058 volts...most balanced sources output a voltage north of at least 4...that seems ludicrous to me. so ill ask for 20db of gain on mine very_evil_smiley.gif

 

though that math doest add up either, 58 volts into the 50ohm load of HE-6s is 67 watts. and you say, but wait it might run out of current, but this is doubtless since that only requires 1.16 amps. and in order for it to pump 1000 watts into 2 ohms it needs 22 amps, i think itll be alright wink.gif. so somewhere above 60 watts into the HE-6s it is!

I wonder how many email Kingwa received a day. He even responded to my email in the evening. He is super!

Oh, I dont understand your calculation btw o_O but nevermind me.

Which part of the calculations did you not understand?  id be happy to explain

Man that's crazy but go for it! The up side is that amp will rock any set of speakers you can think of.

Everything biggrin.gif  for example, how do you know "the amps max voltage output is 58 volts RMS"?  I don't see it ion his website though.

 

^ Edit: oops, I saw it on the website, right in the middle.  Did Kingwa just add that in?  eek.gif

My speaker amp is 50W @ 8 Ohms in class A. It sounds warmer than my Master-6, but slightly less transparent. No difference in bass quality or quantity between them. I don't use the HE-6 via the speaker amp any longer. The Master-6 really is a master of an amp biggrin.gif

Haha yeah i couldnt tell you how long its been there, so im not sure what to tell ya. as for the rest of it, i just used a couple formulas I = V/R and P = VI from which you can also create P = I(squared)R. so knowing that, the rest of it just kind of falls into place.

 

I = current in amps

V = voltage

R - resistance in ohms

P = power in watts

That depends on how the balanced B22 was configured for gain.  If it were mine, for example, you're probably right since I'm only using a gain of 2 per board (effective 4 per channel).  However the B22 can be configured with more gain (2x, 5x, 8x, and 11x).  If it were configured for 8x or 11x, it should be more than enough.  I would even think 5x would be enough.  It just depends how loud you really want to listen to them.  I use dynamics and not orthos.  With the HD800 and a gain of 2x, the loudest I ever use it would be the 12:30 o'clock position on my attenuator.  The HD650s seem to require a little more power so I can go up to maybe 1:30 - 2:00 on the attenuator.  But I never max it out which would be the 5:30 position.  Obviously the orthos require more power but I'd be the B22 you listened to wasn't configured for a higher gain.
