    CAPS v3 Zuma vs Carbon

    Been following the comments on CAPSv3 Zuma & Carbon but am surprised this question never came up so I thought I'd start a new thread.

    I've been happy with using my work laptop as my music server. JRMark is around 1400. Since my DAC only accepts 16/44 or 16/48, I use JRiver to downsample hi-res and DSD music. I also use JRiver to add two small parametric EQ to lower two bass peaks by 2-3 dB. I have never noticed any sonic deficits with these DSPs on my laptop and am very happy with the sound, have no intention to upgrade my DAC or to an async USB-to-S/PDIF for higher bit rates because I have minimal amounts of music in hi-res.

    I'm planning to buy either Zuma or Carbon from Small Green Computer so that I don't have to plug and unplug my laptop all the time. Zuma's JRMark is 4712 and Carbon's JRMark is 601. I prefer the form factor of Carbon. But I'm worried that Carbon may be underpowered to do the simple DSPs that I currently do. Using the Windows widgets, CPU usage during JRiver playback is maximal when downsampling DSD files to 16/44 dithered with the parametric EQs engaged and it is about 7% of CPU usage on my current laptop.

    I was wondering if people have experience with music servers with various CPU speeds engaged in simple DSPs (not full-blown room correction or JPlay) and whether they feel strongly, or not, whether the performance is sufficient to not affect sonic qualities.

    Thanks for your thoughts!

    No doubt you have thought about just spending the same money you were going to spend on a server (soundsike you'd need the Zuma) , upgrading the DAC to handle 24/192 and DSD? Doesn't the price of a Mytek = about same as a Caps Zuma? And the Sonore is a bit cheaper ?

    Why don't you just do that and listen to the files natively and bit perfect?

    Then stick them on the cheapest CAPS if you have to...

    Cheers.

    DAC upgrade & CAPSv3

    Upgrading from Chord QBD76 to QBD76HDSD is in my audio roadmap. Especially when I have built up more HD music into my collection. But it doesn't solve the parametric EQ need unless I'm going to upgrade my home. And DAC upgrade doesn't resolve the inconvenience of plugging and unplugging the laptop.

    But I see that I may have to bite the bullet and get the Zuma unless others have a different experience.

    Thanks for the suggestions.
