Looking for more transparency.

rvpiano, glad it is coming together for you.            
My ARC Sp-15 I use mainly for the three tube phono section (6DJ8) takes over an hour to sound good. Most of the rest of my stuff stays on 24/7.

Truly superior cables are not tone controls. The very best cables I have heard and now own were better in every way than their inferior predecessors. If you think that cables are tone controls you are not listening to really good cables in my opinion.

Elizabeth say's:
" My pile of Furutech AC duplex also took a very long time to all break in. I would say, now from first few purchesed in late July 2018 with a few in August and a few in September.. they all finally have fully settled down like January!"
Wow... Although I've never heard anybody say anything other than that they were great, that is a true commitment. 

My new Morrow speaker cables did the trick.
Night and day difference from my very old Cardas cables.
smoother and much more transparent!

My Morrow interconnect was so good I buy the number 3 and was very satisfied... And yes the break-in was very evident for my ears...But the transparency I get mostly comes from cleaning the electrical grid and the audio grid with passive means because introducing new electronic components does not always lowered the noise floor, it is a trade-off most of the times when you introduce new electronics filtering components because they introduce noise of their own...Passive filtering is the way for me...
