Melco N1ZEX-H50 Runs Slow

[Desmal]

My new Melco N1ZEX-H50 seems to run slower than my N1Z-H60/2. Let me explain: The scroll across the OLED is much slower on the H50 and also the gap between cuts on the album is much larger than the H60. Running Bubble UpNp, I cannot get gapless playback on either unit, but it is much closer on the H60. I did read the post on the quality of the ethernet cables and I ordered a couple of Cat 8 cables to try out. Other problem is I have to run a 30 foot cable from router to Melco.

For better sound quality, would I be better off running the 30 foot cable from router to a switch, and then run a shorter high quality ethernet cable from Melco to switch?
