| Caps for crossover upgrade for Opera Grand Callas Loudspeakers @erik_squires The series cap to the Esotar tweeter is 5.9uf. The shunt cap to the Scanspeak 8545 mid/woofer is 17uf. IIRC, crossover is around 2000Hz. The greatest change with the .01uf Duelund bypass is heard in mids to LF. The change is rather d... | |
| Caps for crossover upgrade for Opera Grand Callas Loudspeakers Just thought I’d chime in here, as I recently installed new Duelund .01uf Pure Silver Foil bypass caps over both series and shunt caps in 2nd order crossover of well broken in ClarityCap CMR in my Merlin VSM-MXs. This is a synergistic combination ... | |
| Digital clock - any recommendations? @mzkmxcv OK, you rooted me out: Esoteric and DCS are expensive junk, and so are laboratory instruments like my Stanford Perfection 10 Rubidium clock specified +/- .05 ppb and < -150dBc/Hz@ 10kHz phase noise. None of this matters with any DAC... | |
| Is a CD Transport the Best Digital Source? @jim204 Interesting that the JCAT USB card made a major improvement for you. I have a JCAT NET Femto ethernet card on order for installation in a QNAP i5 NAS that hosts Roon core in conjunction with SOtM EN-to-USB endpoints. I'll try powering th... | |
| Digital clock - any recommendations? +3 @folkfreak With an Esoteric DAC it's easy to perceive the improvement of an external 10mhz atomic clock powered by a good LPS. Why would Esoteric market the interface were this untrue?Also, if your networked computer audio components have mas... | |
| Digital clock - any recommendations? For that unit you'll need a clock that outputs 44.1, 88.2, and 176.4. Try an Antelope LiveClock and upgrade its wall wart to a good LPS. If you want to go further, the LiveClock may in turn be synchronized to a 10mhz atomic clock like Mutec, Cybe... | |
| 12V Deep Cycle battery with Pure Sinewave inverter for tube amp? I used a 100AH Odyssey PC2150 deep cycle battery to power my modified Sony SCD-1. They have vanishingly low impedance, which is a function both of their design and high AH capacity. It's good to add a large amount of capacitance between the term... | |
| MORE Esoteric problems I’ll come to the defense of the K-01X. Over time I’ve added to it a SRS 10mhz master clock, a better power cord, a LessLoss 64x Firewall, and a Star Sound Rhythm platform. It has been responsive to these tweaks and has proved fantastic both as CDP... | |
| Are the XA 60.8s the best of the Pass amps? When the .8 series debuted I spoke with one of the designers about it. He mentioned that, independent of power capacity, the design of each model in the series is different enough from the others to favor one over another. He personally preferred ... | |
| Is there a difference in sound quality when streaming TIDAL Vs CD player Which sounds better likely depends on the quality of your network and USB DAC implementation. You may need a system well above $10K to hear all that hi-res streaming can be. As Roon applications Tidal/MQA and Qobuz 24/96-192 both equal or surpass ... | |
| How much do we at A'gon influence the industry? I interact with a variety of hi-end OEMs in the course of marketing ClarityCaps. I can’t think of more than one or two who follow Audiogon or other high-end forums, and as far as I can see, they do it only out of general interest. Audiocircle is p... | |
| DAC - Aqua Formula or Aqua La Scala @astelmaszek Funny, I can’t think of anyone I’ve met like me. If I did, I probably wouldn’t like him either.The Aqua pieces are simply in a different class of performance and price than Anthem. Moreover, if you buy into the R2R construct (I do and... | |
| DAC - Aqua Formula or Aqua La Scala Agreed. Reintroducing the output of either Aqua DAC into the digital domain in a budget piece like the Anthem is a bad idea. I've heard the Formula. It's among the smoothest and most analog sounding DACs to be had. If you can afford it, then... | |
