@ryder What was wrong with your D300? Looking forward to hear how the Alpha X sounds on the Diablo.
@swede58 I just received the Diablo 300 but will need some time to compare the Alpha-X NR and Furuteh DPS4.1/FI-50 NCF(R). I’ll report back in due time perhaps by end of the week. I briefly swapped the mains power cables and music sounds less open and dynamic with the Alpha-X NR but that may be inaccurate since I just listened for about two hours comparing the cords. I hope The Alpha-X NR will sound better than the Furutech DPS4.1/FI-50 NCF(R) on the Gryphon Diablo 300 but if it's the other way round, I guess the NR version doesn't suit the high current Diablo 300. With the Luxman L-590AXII I can conclude that the Alpha-X NR sounds noticeably better than the Furutech, direct connection from the wall outlet to the amp.
