Thanks for the tip on the Musical Fidelity PSU
DSpeaker Anti Mode Dual Core 2.0 Room Correction
Has anyone tried this new unit in their system either 2 channel or home theater??? I was reading some reviews and this thing could be a winner. A couple guys in my audio club have tried it and claim it is absolutely the cat's meow!!! One stated it is the best piece of gear he has ever purchased in 55 years of audio buying!!!

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! |
It's more about the power on the cable coming from the computer. When the signal enters into the IUSB it is separated from the power on the line, regenerated and then sent to the decoding devise. In this case it is the Dual core. Many users are very pleased with what it does, the sound is fuller and much better detailed. I don't currently own one, but I have had the privileged or hearing the difference of what one can do at a friends house. I'm on the list for the next shipment. http://www.ifi-audio.com/en/iUSB.html http://www.audiostream.com/content/ifi-iusbpower-taking-audioquest-draginfly-dac-notch http://www.digitalaudioreview.net/2013/01/amr-ifi-iusbpower-review/ Enjoy, R |
