Digital has always, for me, had a detrimental impact on music that had many layered parts. The compression artifacts limited the spatial effects intended by the artists. Clannad’s Banba [RCA] utilises the layering process to great effect. On one song, ‘Na Laethe Bhi’, the layering creates the impression of dozens of voices in the chorus. Generally, the track has always seemed to be artificially enclosed as if the singers were in a smaller space than could fit the perceived number of people. They sounded almost crushed together. With the DSJ it was like the room had expanded. The scale increased markedly and the song had room to breathe. The effect was quite extraordinary and gave me the impression I was hearing the song as intended for the first time. Moya Brenna’s haunting vocals occupied a much vaster area centered among the accompanying chorus that seemed as wide as the sky. Imaging became spot on and the soundstage took on a depth and breadth I had not experienced previously. Chimes had room to float among the singers, strings had room to play! Thank you DSJ for giving this song back to me.
At £3,700 (with an included 1 year Roon trial subscription included) this is not an inexpensive piece of kit. However, the few units I have heard that can reach the analogue heights achieved by the DSJ have been either its bigger DirectStream brother or a handful of other products all coming in at several times the price. Nothing I have heard at this price point thus far has had the word ‘Analogue’ floating in my ears from the start of listening. Enthusiastically recommended.
