Crossover upgrade capacitor question
"Remember that caps used in passive crossover see high voltages and therefore they change shape along with the signal flowing through them - this can add significant distortion in some cases"Both Claritycap MR and Duelund reportedly have design im... 
Experience with FREDs in a tube amp PS
IME in a high-voltage custom full-wave bridge, Cree SiC Schottky surpasses HEXFRED. For low-voltage/high-current filament supply, a ladder of 50V Schottkys sounds better than FRED. In a manufactured 4-pin bridge, IXYS 600V/6.6A SiC Schottky is rep... 
Crossover upgrade capacitor question
Hi Bob, I'm curious why you recommend limiting small bypass cap to tweeter. 
Neil Young Live at Massey Hall 200 g LP,
On this album his chat on top of retunings & guitar riffs drawn from other songs, is part of the poetry. The sound quality of the CD version is top notch, and the close miking is no problem with a solo performance. The story about Old Man is r... 
10 Levels of Turntable Mastery
During my long noviciate of acquiring purported TT mastery, every year or so when I rechecked arm/cartridge set-up I found it way out of adjustment. I suspect it was my measurement tools & skills that were improving, rather than shifts in geom... 
Top resistors
Audiotweak, please post your findings regarding TX2575 vs. TX2352. 
Top resistors
Clabe, good to hear about your improvements. Prior to switching to fast recovery diodes in the Vel, I was always hunting around with the sub set-up and volume level. Afterwards everything just fell into place.For a cheap and effective mod to SBAM,... 
Sell Theta DSPro Gen Va???
I know of one owner of a broken Gen Va (which is no longer supported by Theta) to whom Theta offered trade-in value toward a Gen VIII DAC. However, in view of Theta's withdrawal of support for all prior models during the run up to the recent acqui...

Anyone heard new Pretenders CD?
A fantasic album on vinyl and CD. While listening I kept thinking how much Lucinda Williams & others owe to Chrissie. 
New LPs with CDs inside
Based upon listening to some CDs that purport to use no compression, I agree that compression may be the main offender in the compromised sonics of RBCD-- moreso than sampling rate.It's interesting how some new vinyl releases are coming through wi... 
Capacitor log Mundorf Silver in Oil
It's not unsurprising that the most expensive cap sounds good and possibly best. What remains unanswered is the importance of Duelund relative to gains that can be achieved upgrading other areas of the system. Hopefully this will be explored as yo... 
New LPs with CDs inside
My purpose in posting this thread was partly to find out if progress in hardware & software has led anyone to change his assumption regarding the superiority of either medium. As the gap between these media has narrowed, it's interesting to tr... 
Rain-X as CD Enhancement Treatment
Eldartfort, at a younger age I did indeed test the limit of a turbo-charged BMW motorcycle at max speed. Rain-X on a CD is safer & more suited to age and temperment today. Closer to the analogy of hifi, I have no doubt that the limbic system o... 
Rain-X as CD Enhancement Treatment
At high velocity where aerodynamic friction becomes significant, it may be true that the smooth surface presented by Rain-X on a windshield may increase both maximum velocity and gas mileage.
