| Looking for my first DAC Generic Chinese 9038Pro DAC on eBay. It follows the reference design spec'd by ESS Tech. Easy to mod too. | |
| 6h30 tubes dampers to replace Audio Research ones It is of utmost importance that you source the rings from Audio Research.The right rings for the right mode/vintage of your amp. Some were transparent silicon recent ones are made of cryogenically treated and quantum enhanced black diamond amorph... | |

| heeeelp please audio reserch 5SE - resistor blew up Yea some people can hear the difference in regulator tubes. I can't and you need not show me. We are all here to try to help the OP revive his line stage. I have had it repairing gear that's been "NOSed" by snake oil merchants. Audio Research,... | |
| heeeelp please audio reserch 5SE - resistor blew up Its not the big 27kOhm that blew. It’s the 1k grid resistor to the 6550 pass element. OP sent a pic to me."New old stock" 6550. Members with no tube testers at home are at a HUGE disadvantage. Yes! Test before install is always a good idea but OP ... | |
| heeeelp please audio reserch 5SE - resistor blew up Audio Research, unlike years before, will not respond to you.The local dealer will fleece you.The trusty local tech will tell you the unit is damaged beyond simple repair and it will be 10 bench hours at 100/h.Just replace the damn resistor yourse... | |
| Music I would succumb to under torture Look up a singer by the name of Teresa Teng. Hailed in Asia as the all-time queen of "contemporary" vocals. High-end audio snobs would spend big dollars on vintage Western Electric, Tannoy, and JBL gear to play her poorly recorded cacaphony. Cheap... | |
| Is vintage audio better? I'm starting to look at current (modern) and non-US audio. You can easily recreate the sound of vintage medium-sized domestic gear (note: NOT Vintage Western Electric/Altec/JBL from theater plunder) sound by using vintage tube circuits, tube rectification, oil capacitors, carbon composite resistors, selec... | |
| The Best City to audition High end and Vintage Audio Good to know you know the Silbatone team. I have their 9018 DAC that is unexpectly poor performing in terms of tone and noise compared to 1794 DACs and 9038Pros. Maybe I can find answers through you. | |
| Bypass capacitor questions If it’s a mid-range coupler and you are bypassing say 47uF with a 0.47 to 1uF it makes sense. Further bypassing with 0.01 ventures into the realm of astrological psychics (not astrophysics). Bear in mind there is something called a RC time constan... | |
| Spam Prevention I actually found the counterfeit bills spam rather amusing. | |
| Bypass capacitor questions Sharper transients is your phasiness rightbthere. I think several of us are willing to bet $ you will pull it out eventually esp if you listen to classical music. | |
| Bypass capacitor questions " increase in smear for the impression of greater clarity "teo_audio is a wise sage. | |
| Bypass capacitor questions Btw I wonder how your Thiels have a “coax “board. Are you referring to the PCB that houses the crossover for the mid highs vs the woofer? I have repaired botched crossover jobs by people who just swapped in boutique caps into crossovers and blind... | |
| Bypass capacitor questions Without knowing the crossover topology it’s very hard to give you advice. In general bypassing a dull cap adds sparkle at the expense of phase issues (sibilant sounds move forward) and squeakiness (if bypass caps are too high a value). Your pos... |
