My 1-Ohm O2 amp can drive my 600-Ohm headphones just fine (so that's 600 times the impedance of the amp).
The STX & DX & D1 use the same CMI8788 audio processor, the Phoebus uses the newer CMI8888.
But as far as I can tell the CMI8888 just allows the audio processor to work directly with the PCI-E slot.
Where as the older model CMI8788 (native PCI) needs a bridge chip to work with a PCI-E slot.
Thx again for the explanation
from what I've been digesting from you explaination an older card would suit me better
I am using a max v formula which has built in sound amp already and I've noticed that somehow my shure sound a bit better if its plugged in straight to the motherboard than to my phoebus
(not sure since I'm a beginner)
since I have DAC incoming I might compare it first when its plugged straight to my phoebus and my motherboard
but would you reckon I'll get better sound if I get older version of sound card like stx and pair it with the DAC?
I have the budget to do so anyway...
And I've read some post regarding the tube amp, it says that
Q: Does the Aune T1 DAC utilize the tube, does the T1 headphone amp section use the tube, or do they both use the tube?
A: The Aune T1 is a USB tube DAC with a solid state headphone amp. What this means is that if you want the benefits of the tube, you must use the USB Input of the T1. The amp section of the T1 does not use the tube by itself. Technically, you could bypass the DAC of the T1 and just use the amp but this type of use is not really what the T1 is for. One thing you can do is use the T1 USB input then hook up a different amp to the RCA out of the T1. This will give you the benefits of the tube and allow you to try a different/more powerful amp (though I think the amp in the T1 is quite good). I personally have a speaker amp hooked up this way so I can use my headphones and some bookshelf speakers at the same time from one source.
sorry to keep throwing question but what does a tube does?
