Hi all, I am sort of fed up with the 'dropping' of signal over my network and AE, so I decided to go back to use the good old docking system. I purchased the Wadia 170i last night and hook it up to MF M1 DAC via coaxial. While the out of the box sound a bit harsh, a good run in for a few hours changed the sound dramatically. I do have a e few questions though: 1. I tried with iPhone 4, iPhone 3GS and iPod Touch 32 GB and all of them worked properly. However, eventhough all of them are synced to the same library and music files (apple lossless and 320 kbps mp3), at the same volume level on the amp, the iPhones sound louder than iPod. Why? 2. Eventhough my CDs are ripped to the same file types above, some files shows a signal at 48.1 kHz instead of 44.1 kHz on the M1 DAC. Any ideas why? 3. What is the function of the Mode button on the Wadia remote? I accidently pressed it and the signal shown on M1 DAC was 32 kbps and there is no more sound coming off the dock. Thanks all.
