Right folks, the differences are marked. Rather noticeable improvement, not a subtle one.
For a more accurate assessment, I figured out I need to carry out a more methodological approach with the listening by swapping the cables between each track. So I listened to a complete track with the Wireworld Ultraviolet and upon completion I switched to the Tellurium Q Ultra Silver and listened to the same track at the same volume. I was prepared to do a 3rd switch back to the Wireworld in case I didn’t hear a difference but there wasn’t any need to do so as the difference is very noticeable.
Music used is David Benoit’s “Drive Time” which is a random selection.
The differences. With the Wireworld Ultraviolet, music sounds good and I still tap my feet to the beat. Once I switched to the Tellurium Q Ultra Silver, I realised the Wireworld lacks the control from top to bottom. The bass sounds big but loose and smeared. Sound of instruments such as piano, saxophone and trumpet is slightly louder and 1 or 2 rows in front. With the Tellurium, everything sounds more controlled. Bass sounds more defined and textured with reduced smearing. Sound of instruments sound slightly softer and 1 or 2 rows behind. The tone of piano is more controlled with shorter decay and sustain times which may have contributed to a cleaner sound.
In summary, the Tellurium cable brought better control and refinement to the sound with an overall cleaner presentation. With the Wireworld, music sounds “messier” with higher levels of smearing especially in the bass and instruments sound slightly larger, airier and louder than they should.
I would recommend trying a better USB cable to connect the laptop or computer to the DAC if anyone is still using some cheap off-the-shelf USB cables, or the Wireworld Ultraviolet.
