Pete10:
I'm also interested in the A1 (to drive my MA GR20's, input from pc). I now have the VDAC that I like a lot and it would not surprise me at all if it shares the circuitry with the A1. An alternative would be the valve xcanv8p as pre amp with a power amp. I do not need the other inputs of the A1 and a headphone output would be nice. Unfortunately, MF does not make a matching power amp. Any comments on the comparison, or recommedations on a suitable power amp?
Hi Pete10. The USB DAC used in the V-DAC, the X-DACV8 and the X-CANV8P is the same Burr-Brown PCM 2706. I think that it will be the same in the A1. There are obviously lots of other components in each which means the sound will differ. But I am happy to bet it will not be by much as Musical Fidelity have their 'house sound' as I posted above.
The V-DAC into the X-CANV8P should be a good upgrade. But if you only use the USB part I do wonder by how much. So much so, after reading through loads of reviews I have decided to go elsewhere for an upgraded USB DAC. It certainly makes for a very good headphone amp. As for the preamp, MF are really pleased with that part of the circuitry and push it at every opportunity. Their clear intention is to pare it with one of their, rather expensive power amps. I would honesty try phoning MF details here;
clicky and ask for suggestions in your budget. I found them to be very helpful and bought headphones based partly on their recommendation.
