Customer Review
- Reviewed in the United Kingdom on 27 August 2024I recently upgraded my audio from my hifi/computer system to optical feeds from source to headphones, and to speakers via my amplifier.
I already had an FiiO DO3K digital to analog converter and was more than happy with the sound when connected to my vintage Sennhouse HD600 headphones. Only one minor ptoblem, the fixed volume level, although set at a good rate, was slightly under my preferred listening level. So, since it was so cheap I bought a Prozor 192K optical digital to analog converter, (the one with just optical in and only a jack plug out for headphones) which has a volume control on it..
Yes it did give me the extra volume I was seeking, but while both mastered the full range of sounds, the changes to the sound the two DAC's produced was revealling .
The DO3k produced a smooth, well controlled sound, extremely good thumping base, with perhaps a lack of sharpness to the otherwise well controlled treble end. The stereo imagery is excellent and the music integrated into a stable soundstage image.
The Prozor definitely had a higher volume level with it's pot, the treble I suppose you would call brighter, with more bite, the base, although very much still there, had slightly less impact. Perhaps it was the 'brightness' of the sound, but the soundstage was I feel more confused. To judge this more completely I think I need to try both of them on something more like orchestral music to establish how I feel about the soundstage that type of music presents itself given these two different DACs..
My current feeling is that for the pop end of the market the Prozor might be preferable, but I am sure that for orchestral type music, where the soundstage is everything, the FiiO DO3K is my preference.
One thing that surprized me was that the cost of implementing this optical sound and switching system was far less than the previous analog setup I had, so that's good news.
