I have actually been comparing it directly to the Magni/Multibit stack and it meets/exceeds it depending on taste. The basic 299.99 version is actually very similar to the schiit stack. The most noticeable difference is that the Multibit increases the bass a bit but due to this I would say the play is more Neutral. I also think the Plays USB implementation is better than Schiits, I usually use optical with the Schiit as I found the USB to be finicky.
If you go with the V6 Vivid version, the separation of instruments improves and it sounds more open/detailed as a result but it may not be to your taste depending on your headphones. I find a lot of songs sound TOO separated on the HD 660 S, its like you are running them through a analysis program rather than listing to music. Its fantastic with the 650 though, as it benefits from the open sound. I prefer to put the Basic NJR op AMPs in the SIngle channel slots when I use the 660 S as it tones down the vivids a tad, but I like all Vivid with the 650.
My main gripe with the Play has been that I think the gain is too high and its causing hiss even with the 650s 300 ohm impedeance. Tried a attenuator which got rid of the hiss but killed the bass. However the mod Burson mentioned here seems to have helped. I pulled the caps out earlier today and it did make the Play Quieter. Have to turn up the volume a bit more now, but the hiss reduced. I was also getting some feedback when I actually plugged in the headphones or touched the plug near the headphone jack and that has gone away after the mod. Still need more testing but seems to have improved the Play thus far.
I agree, as much as I hate to admit... this USB implementation is top freaking notch! It's quieter than the Coaxial input form my EL Dac <.<
Now it turns of sound... I'm not quite ready to spill the beans... but with my initial impressions the Play is very much an ESS Sabre Dac, there's a quickness to the sound... with a slight focus on ambient noise over micro detail, in a sense it's ever so slightly more exciting! The Play also has a nice sense of space to it! Not so much airier but a bit wider, echos in a room extend just a little longer
Now the EL Dac on the other hand... has this weight to it... drums are hardier, vocals are... chestier, it's not that it's slower but... there's just that much more decay and resolve in the release/sustain, ambient noise is not as evident and the top end is a little sweeter/better resolved... while the echo of the bell in "drum an bell" doesn't sustain as longer it's vibrato is more evident. The slight changes in pitch as it fades into silence are more apparent, there's just better texture all in all. But it's also not as quiet... I can't say that it's relaxed because micro dynamics are also more apparent on the EL Dac but... there's just a weight that I appreciate, but this weight also adds a some what... almost intimate character, not as wide as the Play but neither sound any more or less airer than the other
I'm currently running through my Chesky Headphone Demo disc play list and listening to "drum & bell" along with 4 voices with my Schiit Vali as the amp and my HD 800 [silver cable'd with SDR mod]
Given how good the Line out in the Play is I'm confident the Classic an Vivid opAmps will take it to that next level!
Though the stock module has a nice tonality... the imaging could be a bit more 3D, but with music it's fine and more importantly it has a good balanced pleasant sound, with nice resolve. While at this time I still feel the EL Dac+ Vali 1 does a better job dynamic headphones, switching into my Planars the play is clearly better, I guess I should also invest in a $100 solid state amp... but honestly I don't really see the value in going that route...
I just feel a good all in one Solid State Dac/Amp is an amazing value, I started out with such a set up and added in tubes later. While I haven't yet heard the schiit stack and won't compare it, in terms of value I think going Single End with a Solid State is the best place to start for new comers. All in one's present an even better value up front, though they can hold you back later down the line. With how popular the Hifiman/MonoPrice M1060/LCD 2C are becoming alongside the HD 6## series, I think new hobbyists are going want prefer the flexibility of solid state over the specificity of a tube system
Given how it scales with the Classic an Vivid OpAmps and how well the Dac it self performs I really do think you guys have a winner here, most impressive though is this USB implementation! Holy freaking smokes it IS CLEAN, easy to install and works like magic!!!!!!! Gawd good clean usb ALONE makes this a winner! I can't tell you how much I hate usb... heck I just bought a SECOND usb to Coaxial converter for my system because I continue to have such a bad experience with USB.
@Burson Audio @Burson B, you guys are really setting the bar for how a USB implementation should sound!!!!!!
