Unfortunately no, I have not had a chance to listen to or try the Minibox. I am curious how the Minibox sounds. Maybe at a meet sometime. On another note (there goes my wallet again), I just received my Centrance HiFi-M8 iDevice version and am doing A/B comparison to the 901. I am using a 160GB iPod Classic with the HiFi-M8. I am using a 128GB SDXC with the 901. All of my music (eclectic tastes ranging from Miles Davis to Bartok to The Rolling Stones to Basia to Tupac to Toto, etc., etc.) is lossless 16bit/44.1 in either ALAC, FLAC, or WAV. First impressions: The 901 sound quality is two or three steps above the HiFi-M8. There is more air and pinpoint imaging/staging with the HM-901 compared to the HiFi-M8 in my opinion. In addition to the HM-901 multiple note and articulate bass. I can actually hear the different bass notes of Eminem, Nelly, Akon, etc. I can also hear this with the HiFi-M8 it's just I have to listen harder. All IMO. However, the HiFi-M8 has greater flexibility with the impedence, gain, bass, and treble selectors. In addition to the ability to listen to my laptop, iPad, iPhone, and iPod via the HiFi-M8. I only wish I could do the same with the 901. Yet, so far (only three days; maybe 8 or 9 hours total) when I just want to listen to music and it's well-recorded 16bit/44.1 or Hi-Res (separate SDXC card for the 901; laptop for the HiFi-M8) I find myself enjoying the sound quality of the 901 more than the HiFi-M8. More impressions to come. As always YMMV. We live (and listen) in a great time!!!
