At the beginning of the year I was lucky enough to pick myself up a Croft pre and power amp . These amps are so good that I have decided that this is the end of the road for me in terms of box swapping . I then decided to upgrade my mains cables . I've always made my own from Belden mains cables and decent plugs , however , I decided to treat myself . I contacted David Brook at MCRU , gave him my requirements , and a budget .
The first cable arrived promptly and IMO was really substantial and very well built , fitted with silver plated mains and IEC plug and a covered in a very nice black braid .. I plugged it in between my mains socket and RA mains block and it didn't take much time for me to realize that the MCRU cable was a very audible upgrade in terms of SQ over my own home made efforts . There followed another which was used between my mains block and Croft power amp , again another significant improvement in SQ . Last week I bought the same power cable for my preamp and after some listening I have come to the conclusion that the culmination of all three cables fitted have provided me with a profound improvement in all areas of my systems SQ . My system has changed for the better in all areas . Bass is now deeper , cleaner , and more tuneful . There is more low level information emanating from a much quieter background . Improvements in mids include singers sounding more natural and easier to understand . The top end also sounds more natural . Soundstage is bigger with better separation , singers and instruments now in their owns space . Sometimes when I close my eyes the singer , or band , seem to be in the room . All in all a wonderful upgrade in SQ for not too much money .
The MCRU mains cables  have provided me with an upgrade in SQ which I believe can't be achieved by any other means . David has been a top guy to deal with throughout , and I will probably be back for more when funds become available .

Oh... and just to clarify . I have no connection to MCRU . I'm just a very happy customer
