| Does anyone care to ask an amplifier designer a technical question? My door is open. Hello @ramtubes,I have a DIY 300B SET.Input tubes are 6sn7, driver are 6f6 in triod mode.I use coupling capacitors (Duelund Custom Cu) between input, driver and output tubes.I use 5K output transformer James Audio.My speakers Altec 604E ~100dB sen... | |
| JAM by Duelund Hi @grannyring ,Does a capacitor quality in the 2nd order speakers LPF make a big difference?If yes, Which producer and type can you recommend (I need 8uF)? Do you like Jupiter VT?Regards,Alex. | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Yesterday I updated cables from Werner Jagush crossovers to Altec 604"E" speakers.I used Belden 9497 and I update it by Duelund Sn-Co DCA16GA.I use 16ga cable for both mid-base and compression drivers.Despite zero break-in time Duelund cables soun... | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Hi @pumpweel ,I had some such experience before.I used LEGENBURG 22ga for tonearm to MC step-up transformers interconnect cable.I changed it to Duelund 20ga cotton version.At first Duelund sounded cooler with less midrange bloom. But separation, s... | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Hi @pumpweel ,I like Neotech LEGENBURG.I use this wire in my amplifier and phonostage for many years.But I'm curios if I can improve the sound of my amp using Duelund Cu-Sn wires. | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Hi @grannyring ,I understood you.You wrote: " compared to the cotton 12ga it will not sound as open, real, and lively due to the synthetic covering".What I want to say, these drawbacks may do a sound of synthetic covering 20ga more balanced compar... | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Hi @grannyring ,Duelund 600volt 20 avg can be used for headphones cables. Cotton isolation is not as durable as plastic one.I'm also thinking about to upgrade 50 cm long run of cables from RCA inputs to input selector in my 300B integrated SET. No... | |
| Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG Has anybody tried new Duelund 600 volt Cu-Sn 12 AVG and 20 AVG cables?How do they sound compared to regular Duelund DCA20GA and DCA12GA? | |
| Duelund cast Pio Hybrid Copper/Silver or Rs series with Silver Bypass PIO Hi @grannyring ,Did you use Duelund copper or Tin plated copper wire?Regards,Alex. | |
| Duelund DCA16GA Hi @laaudionute, Did you try to build interconnects without copper mesh shielding?Regards,Alex. | |
| Duelund DCA16GA Did anyone try to build an interconnect cable with combination of Duelund DCA16GA on cold wire and DCA20GA on hot wire? | |
| Duelund DCA16GA I compared Duelund DCA16GA and DCA20GA as RCA interconnects.Yes DCA16GA has fuller base and lover mid and less dry, but DCA20GA sound much more vivid.So it depends from overall system tonal balance. In some dark sounded or dull systems DCA20G... | |
| Duelund DCA16GA Hi @grannyring ,Which Cardas RCA do you use? Is it SLVR or other type?Have you compared KLEI Absolute Harmony RCA to Switchcraft RCA or Duelung Gold RCA?Regards,Alex. | |
| "New" Western Electric wire Hi @larryi,Have you compared EML Meshplate 300B tubes to regular EML 300B?I think about time when I have to replace my EML Meshplate 300B. Are regular EML 300B good enough?Regards,Alex. | |
| "New" Western Electric wire I have old WE 300B reissue tubes.They are good but a little overrated tubes.I bought TJ Mesh 300B and liked them more compared WE 300B reissue. I sold my used 300B WE reissue two times more expansive that I bought them new!After that I bought EM... |
