Pros: Superb performance of CD/SACD/DAC
Cons: Not enough manual control nobs
The first impression was fluidity and being spaciousness so that I stood in the concert room.
I felt the 3 dimensional space of musical sources.
It was not the case with Bifrost without Uber upgrade, which was once my savior of Mahler symphony 8.
The symphony requires high definition to represents 1000 men and women choirs and extended orchestra with adding pipe organs for example.
With 105, it seemed to carry me to real concert hall.
However BDP-105 seemed to transport another level with liquidity and musicality.
it forgave much lower quality recording down to 256 rate as usual itune source.
Another noticeable improvement is the SQ of wind instrument when it plays back Wagner Prelude of Tristan und Isolde, which was so sweet to my ears.
After upgrading Bifrost to Uberfrost seemed closely up to BDP-105.
However the BDP 105 shines when it plays CD or SACD. I heard the 1st time Kleiver's Beethoven sym.5 without grainy sound at the introduction.
All Mahlers are now sining now in far different level of SQ in comparison to Flac files through any other combination of machine.
It saves all my collection of CD and SACD, and hence provides far more value on them.
Another notable thing is that it saved my oppo DV980H which is now acting as another SACD transporter without degradation of SQ due to the versatility of digital connectivity through HDMI. It serves a media center for almost everything from computer and other sources.
