| Bass and Treble Dials Unsound,That would be really interesting to insert such device in a chain spdif-in spidif-out but I would still stay out of correcting. Timlub,It looks like you know your caps. Outstanding Mylars? - no way (Dielectric Constant = 3). It is probably... | |
| Bass and Treble Dials Timlub,Capacitors used in analog tone controls have tolerance of few percent producing different phase shifts between channels. Same goes for limited track to track matching of the tone potentiometer. Capacitors, in addition, have dielectric absor... | |
| Premature wear from power-cycling? I don't think so. It might wear tubes or switches but is safe for semiconductors and caps. Electrolytic caps will get momentary temperature increase because of large current going thru internal resistance (life of electrolityc cap cuts in half for... | |
| Bass and Treble Dials "Rooms need tone controls"Room treatments improve clarity and imaging. Tone controls destroy clarity and imaging. | |
| What is “warmth” and how do you get it? Learsfool - jitter is a form of modulation. It creates in frequency domain sidebands of very low amplitude - still quite audible since not harmonically related to fundamental. This amplitude (order of <-70dB) is proportional to level of fundame... | |
| What is “warmth” and how do you get it? "I am unaware of any naturally occuring 'harmonics' in an electrical signal. Only distortion of what ever type."Harmonic distortion measurement is done by feeding pure fundamental with no overtones (sinewave) and subtracting the same fundamental f... | |
| Bass and Treble Dials Sputniks, Adjusting treble and bass can do more harm than good since nature of recording deficiency (if any) is more complex than just treble and bass. It shows in market demand - no tone controls in most high end systems but tone controls in ever... | |
| Oh how I wish Class D amps ... "Audiofeil, you know how low ICE impedance runs"It is 10k - just a little low but many class D manufacturers use additional input circuit that increases impedance. My Rowland Icepower uses THAT1200 instrumentation amp to obtain 40k input impedance... | |
| Success Rolling Opamps in EE Minimax DAC I finally replaced opamps in Benchmark DAC1 with OPA1612 and after initial brighter performance sounded a little mushy. There was a LOT of energy (slam) in the bass and extra extension but midrange became muddy. Today I replaced them again with LM... | |
| OPA 1611 / OPA1612 any Impressions Tubey, better late than never - I just replaced all NE5532 amps in Benchmark DAC1 with OPA1612 and play it so far for few hours. NE5532 is a very good amplifier especially for the price ($0.5). OPA1612 is fuller sounding - especially lower midrang... | |
| Oh how I wish Class D amps ... Dob, I'm confused. I thought that warmth of tubes IS euphonic coloration since tubes enhance even harmonics (artificially added warmth).What is "absolutely artificial origin" and why it is attributed to class D only. Why details are supposedly los... | |
| Are audiophile speakers turn on for single women? Jazzybs, Yes, attraction to women is a drawback and even can be financial disaster for many, home (lost) being the most expensive part of the audio system. Meeting women at the concert is good for common interest in particular music genre and migh... | |
| Oh how I wish Class D amps ... Simon, I checked Spectron website - very impressive. 100kHz bandwidth and 65A max current is not easy to do. I am especially impressed with bandwidth - less phase shift in audio band. Spectron will be possibly my next amp. | |
| Oh how I wish Class D amps ... Spectron,Switching power supply offers many advantages such as ripple that is easier to filter out, voltage that is line and load regulated and transformer that can deliver same power at high frequency at 1/10 of size. The problem here is that SMP... | |
| What is “warmth” and how do you get it? According to Technical Director of Benchmark John Siau, DAC1 that I own, was specifically designed not to sound warm but rather natural without enhancement of any harmonics odd or even. Enhancing even harmonics does sound really nice with guitar o... |
