jafant - I do love the R&D and do appreciate the support and interactions I get with you guys. I’m glad Rob is pleased and hope we get those Purity caps sometime soon. The new order seems to run on snail time.
It is difficult and frustrating to be working against the current. But, progress is being made. The declarations here about Cardas Clear Beyond caused me to overcome my bias from earlier Cardas wire which I found to be warm and dark. I require neutrality and now have a sample of their 15.5 gauge internal hookup wire for comparison. Tests this week!
In the general news department, Bill Thalmann of Music Technolgy in Virginia has finished upgrading my Classé DR6 and is working on the DR9s. He is also upgrading the CS3.5 equalizer which has been upgraded to best professional specs by Jim Williams of Audio Upgrades in California. I’m looking forward to visiting Bill to compare JT stock against JW, against BT upgrades and finalize that project. I will say that in my trials here, JW’s upgrade is a significant improvement over Jim’s (budget constrained) 1987 design. JW used a bigger transformer, regulated power supply, faster and quieter transistors and a couple more bypass caps. JT’s design had all styrene caps and metal film resistors which came through unchanged. JW’s upgrade has a more authoritative bottom end as well as a cleaner, more transparent upper midrange. The previous ’sparkle’ was an artifact. Progress, slowly but surely.
