Assuming my source is lossless on my iphone; what quality/bitrate will be sent to these headphones via bluetooth?

Foobar sounds so much better than iTunes.  Even in directsound mode...

I'm using the same settings in both programs. WASAPI Push. Bitmatched 16bit playback all lossless files. J River is much more dynamic sounding?  Any one else have the same experiences?       

Going to try some abx tests

Yes I know it doesent make sense.  I just got into foobar with WASAPI Push (Bit-Pefect Play back) on my Titanium HD (Audio Creation Mode)   My entire collection of songs consists of ALAC.  I figured why not convert a song to FLAC and see if there's any audable diffrence?   Well after about...

Nothing you can do about that untill a software update.   Honestly you should use J River with the WASAPI.  It blows itunes out of the water. 

DAC on the Titanium HD is outstanding.   I recently starting using foobar with WASAPI "exlusive mode" (bit-perfect)  and must say the detail level has increased.  Make sure to set your conrol panel on the right settings.    

Well I just returned my pair, had them for about a week.  The clarity and separation was outstanding but I kept finding my self rasing the volume to hear the vocals and all I kept hearing was more bass and treble which lead me to my refund.    My M50's maintain more foward mids than the pro...

Just bought another pair of 598, (i previously had a used pair and loved them but sold them because I needed the cash at the time.   This time I bought I brand new pair off ebay for $230!   Cant wait.    The reccessed mids on my M50's are really starting to bug me..

Just bought this card guys, intailly (Xonar was way to bright for my liking)  Hope the blaster delivers.    http://www.newegg.com/Product/Product.aspx?Item=N82E16829102033

Just the cost of the Arcam r/dac ($480), everything I bought and didn't like was returned promptly for a full refund...     My upgrade's went, HRT Music streamer II, Xonar STX, Emotiva XDA-1, and now the Acam r/dac.  

About 2 hours in with the Arcam and I'm finally happy to say Goodbye CD Player!!!!     The Arcam r/dac detail retreival and BASS is apsuletly outstanding.  Very laid back but detailed response without that "bright" cold digital feel.      Finally satisfaction with a DAC!!!        

I will be picking up the arcam within the next couple hours, impressions soon to come. 

Yes, 1GB of ram for XP, and 2GB for 7.
