Dacmagic Hype...Or is it just me...

post #1 of 11
Thread Starter 
Hi All,

Have been reading this forum for quite a while, but this is my first actual post on it.

I have always liked quality music and recently learned about what a good headphone amp can do to improve the overall sound of a good headphone.

After some listening and comparing I bought myself a Graham Slee Solo headphone amp in combination with a Sennheiser HD650 headhpone. Both make a huge difference in how I experience music these days. (in a very good way)

The next thing I wanted to tackle is to get great audio from my pc. I have a Xfi Elite Pro running in audio creation mode with bitmatched playback enabled. Although I thought the sound was already very good, I kept reading about what an improvement a dacmagic would be and that it was an absolute bargain that gives a lot more expensive dac's a run for their money.

Finally gave in to the hype and bought one. I must say, Can't hear any real difference between my Xfi elite pro and the dacmagic. A/B'd for hours on end. It makes me wonder if the elite pro is that good, or if my ears are that bad. Don't think it's the latter as there was a huge improvement with the new headphone and headphone amp, though I'm sure the dac would have been a much more subtle difference.

A dacmagic is more expensive than an elite pro, so the actual reviews where it is said that the dacmagic gives a lot more expensive dacs a good run for their money sounds strange to me, as the elite pro to me sounds just as good...

Not going for a refund though, as it's easy to connect multiple components to it and it provides a way to route audio to my headphone aswell as to my speaker amplifier at the same time.

Please feel free to criticize my hearing or to give me your insights or experiences in this kind of situation.

regards

Pascal

Generally speaking the differences betweeen DACs are far smaller than the differences between say speakers or headphones. There was a blind test that pitted a Benchmark DAC1 against a Behringer and nobody could tell them apart.

In my experience the biggest difference is the output volume, when this is adjusted for the big differences frequently disappear.

well, there's the new toy syndrome, the shills that get free units if the reviews are good, those that fall for placebo to keep justifying their expenses...high end audio is one big road w/ lots of signs

Your experience certainly isn't unusual. Differences between well-designed and implemented electronics are pretty subtle, and those who hear them, sometimes even those who don't, often overstate their effects. Your experience may just be a testimony to your self-awareness, and good hearing.

I don't recommend testing the Slee against much cheaper amps with enough headroom to drive your 650s, you may experience a similar disappointment. I personally find that the overwhelming majority of the sound quality is in the transducers and having enough power to drive them. Everything else, except for the recordings, is incremental when it isn't psychological. Please take no offense. It's only MHO. YMMV.

How are you connecting the DacMagic to your PC? Are you doing an A/B test by switching from the analog to digital out on the X-Fi? If that is the case you are still relying on the X-Fi to send the DM a clean signal. If you're using the USB input on the DM you are getting a lot of jitter which is probably why you are not hearing its true potential.

If its possible try to borrow a cheap USB to SPDIF converter like the Trends/Musiland/Teralink-X and redo the A/B test. This way you are not using the X-Fi for the SPDIF signal and you are avoiding the crappy USB input on the DM.

Yes but the dacmagic should be more detailed and the bass will be more textured than the x-fi.
It should also be more balanced.
If you're expecting a HUGE difference though, you won't get it.

Thanks for the replies

@ Phelonious Ponk:
I actually did some testing in the store with cheaper headphone amps and spent quite some time listening to all of them. I found the differences to be pretty audible. My personal taste went to the solo. Could very well be that someone else finds the cheapest one the best, but I guess that's subjective. Must admit there were more expensive options aswell, but to me, the solo sounded best. No regrets there.

@StateRadioFan
The dacmagic is connected using an spdif coaxial cable from the breakout box from the elite pro. As I stated in my previous post, I'm running bit matched playback which means the signal (should) stay untouched until it arrives at the dacmagic. From there it goes to my headphone amp. The elite pro goes from the card directly to the headphone amp. I could try using the usb to spdif, though I doubt it'll make much difference. I thought the whole point of the dacmagic was to provide an audio upgrade for your current soundcard.

With a good jitterbuster, the difference lies in what you don't hear. The DACMagic is reportedly a very good jitterbuster.

I'll take Toslink over USB, and a battery-powered laptop over a mains-powered desktop. Placebo ? I dont believe so - the Topaz still sounds good after several months of ownership, and its definitely more DAC than amp. Go back to the headphone out on my MBP ? Never.

Why ?

You have an input stream and an output continuous voltage signal, it is hard to see where notable differences might come from if both DACs reconstruct a waveform accurately with minimal noise or distortion

The Solo is a fine amp. Enjoy.

Just my 2 cents

I have the DacMagic and find it truly improves the experience I get from my sound. However, the biggest improvement came from more power to the phones. No DAC will sound right unless the phones are driven with proper amplification. Differences in the DAC are likely to be much more subtle with a good headphone and amp in place. However, let the DAC burn in awhile, 50 hours or so, and see what you think then. Some have reported better sound. http://www.head-fi.org/forums/f7/cam...ad-ii-430326/]
