Dears,
today there was the comparison between the Ref1000 MK2 and the Ref500M.
The source was the Bel Canto CD2+DAC3Vb, Modwright LS/PS 36.5 combo and Gemme audio Katana. All Cables was Oyaide Tunami.
Ref1000 was leaved always on, where the Ref500M had only 30 minutes of warm up. Despite of this, the ref 500M was better in every aspects. The 500M sounds sweeter on the voice, more detailed on the bass and far away more extended and refined on the highs.
Another test we made, clearly show how better was the RCA versus the Balanced interconnection. RCA sounds more transparent and with an improved controlled bass.
I will certainly go for the 500M!
