Hi "ribit"!
I use the M1000i for some years now. Compared many other cables (Van den Hull The Second, Van den Hull Thunderline, Audioquest Quartz, JPS Labs Ultraconductor, Harmonic Tech Precision Link, Kimber PBJ...) to them. Always liked the Monsters better. I think nothing in their price range(especially when buying second hand!) outperforms them. I'm still looking for better cables for the money - but with no success.
Be sure to have a higher quality front end. With some lower price/quality cd players you can do/match better somewhere else.
I must recommend them highly!
You'll hear from many people that they don't like Monster's but I don't know why... I like them a lot!
Hope this helps!
Best regards,
David D.
