Teo Macero...RIP...
The obit reminded me how much TM's creative post-production tape splicing & looping techniques shaped the sound of Bitches Brew & other Miles albums of the period. It appears TM and MD were at times cojoined like George Martin & the Be... 
Tube rectification
Many components with tube rectification also use SS rectification for select circuits such as filament supplies. Most tube components with SS rectification also fail to use the best fast- or zero-recovery SS rectifier bridges made of Schottky(or i... 
Implications of Esoteric G-0Rb atomic clock
Rather than open yet another thread on MP(I've heard MP & yes it does sound good), I'll address the post by observing that the manufacturer's claims concerning MP theory of operation remain opaque & controversial. There has been too much d... 
Suspended vs. non suspended turntable
The springs I'm using are rated 40-60lb. each & six springs are used to support a 100lb TT plus a 200lb. sandbox. 
Implications of Esoteric G-0Rb atomic clock
Dazzdax, The mods I've made to my CDP that have obtained the most audible improvement are refinements to DC power into the digital section: power to master clock, but also separate discrete power circuits into DSPs and motor/servo control througho... 
Implications of Esoteric G-0Rb atomic clock
JH's point regarding frequency is that a crystal clock is subject to transient fluctuations in output frequency caused by power supply variations & ripple, whereas the output frequency of a rubidium clock is inherently stable. He states that a... 
Implications of Esoteric G-0Rb atomic clock
Jitter occurs mostly at the DAC, whether with music server or CDP. 
Which sub - JL Audio Fathom or Velodyne DD?
Curt at Velodyne tech support mentioned to me that the largest DD was faster & more authoritative than smaller models across the entire frequency range, due to minimal strain placed on the servo & plate amp by the short excursions of the l... 
Implications of Esoteric G-0Rb atomic clock
It's a fascinating product review & survey of the jitter problem. If as Joe Harley observes, the ear can easily discern improvements in word clock accuracy down to +/-0.05 parts per billion (translating into jitter reductions on the order of t... 
Suspended vs. non suspended turntable
Dan_ed, Admittedly, it is speculative to theorize concerning the impact of extreme LF seismic activity. However, though the effect of acoustic resonance & its harmonic content at frequencies above the fundamental LF tone is unpredictable, it i... 
Any updates on the Nova Memory Player?
The Memory Player (in combination with Scaena line array speakers) was the best sound at HE2007. The system had uncanny resolution, along with silky smoothness & jet-black background & complete lack of strain rarely experienced with RBCD. 
Tube amps have a signature sound
The longer I've lived with tubes, the more I've tried to purchase or modify tube components to eliminate that tubbey midrange bulge that sometimes comes at the cost of sluggish dynamics and mediocre bass control. Somewhat rare is the tube componen... 
Trumpet cds like Chinatown
Enrico Rava's new one with Stefano Bollani "The Third Man" is pretty far out there as well. 
Suspended vs. non suspended turntable
Based on what I've been able to prove to my own satisfaction by tweaking a VPI belt-drive TT, I'm in agreement with Halcro regarding the merit of a non-suspended TT, but sited on a platform that provides a decoupling suspension. An unsuspended TT ... 
Tube Rolling on BAT Preamplifiers
My thought is that the amount of time that a tube performs "optimally" before audibly degrading is the practical measure of its lifespan & should be considered when judging its value. In the VK75SE at least, a fresh 6H30pi(EB) sounds better th...
