The Rule of Twos

 When customers ask me about burn in times for PranaWire Cables. I tell them my rule of twos:

the most significant changes seem to happen after two hours, then two days, then two weeks and finally two months.  Is this hard and fast? Not really, since I have never had a timer on to gauge these things exactly, but the approximation is useful and seems to be borne out by a recent email from my customer, A.M.

"It is now been five months since I received the Nataraja cables and I thought I should report on how I have found them. They have been in the system approximately 34 days. … I don't know the actual playing time but I would guess it is something like 600 + hours.
 
… I am very impressed. It took a couple of days for the sound to open up and since then it's never been anything but good. It has taken a long time however for everything to come together. The bass in particular took 450 hours (perhaps 350 hours actual) to become focused with extension, weight, scale and texture coming together… Since then bass quality has gone up another level every hundred hours or so and it appears to be still evolving. This has had a beneficial effect on the whole frequency range. The center of gravity seems a little lower and everything somehow seems more solid and powerful. I have had to turn the volume knob down 3-4 clicks to achieve an equivalent volume. The sound is tonally richer without any apparent loss of clarity or darkening.
 
“the soundstage noticeably increased in depth and height to be positively cavernous on some recordings and with a stronger sense of musicians being in the room.”
 
The Nataraja cables have a similar sonic signature to what I described about the Vajras – spacious (the soundstage noticeably increased in depth and height to be positively cavernous on some recordings and with a stronger sense of musicians being in the room) resolved, dynamic and utterly beautiful. In particular the sound is noticeably more dynamic. The impact of the Nataraja cables is like introducing a good preamplifier with increased drive and in room presence, tighter timing and a more full-bodied sound. Classic rock has been a bit of revelation, rediscovering old Wishbone Ash records, Cowboy Junkies, Dylan, Humble Pie, Rolling Stones, Flaming Grovies, JJ Cale, Robin Trower …. and Miles’ electric Jazz  J
 
Compared to the system with just the Vajras, the sound with the Nataraja ICs has more of everything. The sound is significantly better, which is what I had hoped for, but how much better is surprising. As I've said, the cables still seem to be evolving and there was a noticeable improvement in SQ between 700 and 800 hours (nominal). Last night I was glued to my seat for eight hours totally absorbed in the music. I'm still feeling the afterglow. There is another 26 days before the two month mark is reached so I will be interested to hear what further improvement there is still to come.
 
You have made me very happy. Thank you so much!!!"
