DSpeaker Anti Mode Dual Core 2.0 Room Correction

I use a 12v battery ps on mine and found that it sounds much better than the supplied wall wort. I use my Dual Core as a Dac-Preamp. The D/C sounds less "hard" with better sound stage, and imaging. I would highly recommend looking into an upgraded ps for the D/C. My BPS is a custom job and I'm trying to find a reasonably priced 12v linear supply for comparison.

I have a 12v car starter, which is essentially a rechargeable battery with both battery leads and a cigarette lighter output. It can be used for an audio power supply - and recharged between uses. I will try that out. I've been in touch with Toni at DSpeaker, and he told me that users have reported that the Musical Fidelity vPSU mkii ($129) has led to improved sonics. I ordered one from Audio Advisor to try on their 30 day trial. Parts Express sells a 13.8v regulated power supply for something like $40. Toni told me that 13.8 is OK, but not to go any higher.

Thanks for the tip on the Musical Fidelity PSU

Spent some time playing around with the unit today, and here were my observations:

- Definite benefit from switching to a battery power supply, when using the unit as a DAC/preamp. I haven't tested the affect of the power supply when using the unit in the purely digital domain.

- As a DAC/preamp, I like the clarity of my Wyred4Sound DAC2 better. But I want the room correction.

- The best sound I got was by placing the DSpeaker in front of my Wyred4Sound DAC and using it entirely in the digital domain. So far I've only tried optical cabling from my Macbook Pro to the DSpeaker and further to the W4S DAC. I will try the USB connection to the DSpeaker at some point soon.

Using the usb input form your Macbook Pro will sound better than the using the optical out. The optical out will produce a lot of jitter, and you have the latest firmware with the asynchronous USB. I have tried my D/C with lesser transports and there was a very noticeable difference. The battery charger that you are using is OK, but not the best for battery use. It will give you a window at what a battery ps can do, but without it being capasitor filterd you will get some noise from the battery. I know this since I have tried it both ways, and a capasitor bank after the battery is a must.
Look into an IFi IUSB it will take your computer audio sound quality up a huge notch.
I have had my Dual Core since August and have played around with many of the different features. The measurement feature will really help in dialing in your room. There is somewhat of a learning curve with the Dual Core since there are so many features that will improve your sound quality.
I had a Buffalo 32s dac (ESS Saber 9018 chip) and at first didn't like the D/C dac, but after a month or so of comparison the 32s found a new home.
The Dual Core is one serious little machine that will make huge differences to the sound quality to any system. I had mine for four months before I got a call from Tim Ryan (Dspeaker US Distributor) and he spent an afternoon showing me how to better dial in my system. I thought I had good sound,and when we were done I had GREAT sound!
