Hi @donsachs , Thank you for good words and help. My next project will be a phonostage. I have a DIY phonostage I built in 2011 based on EAR834p schematics. In my phonostage I used better parts (air capacitors) and power supply (with LCLC power ...

Hi @lynn_olson The driver tubes are 6f6 in thriode mode. 6f6 are Torvac brand (probably made by Mulard).

Thank you @lynn_olson ​​@donsachs ​​​​@atmasphere for your advice and answers to my question that helped me to build the 300B SET amplifier. https://photos.app.goo.gl/4LUJVLJ3LuuW32yE7 The amplifier sounds realy good - fast, transparent with d...

Montreal Audio Fest 2024
Hi @noromance , You are welcome! Regards, Alex.  
How important is the efficiency of a speaker to you?
In my experience low sensitivity speakers not just make unpleasant compression but also mask microdynamics and texture. It is so obvious that producing low sensitivity drivers is much cheaper. Weak magnets are cheaper, heavier diaphragms are cheap...

Many audiophiles underrate the contribution of pre and power amplifier in sound systems. In most cases an extraordinary amplifier with average speakers sounds better than an average amplifier with extraordinary speakers.

JBL K2 S9900 vs Klipsch Heritage Jubilee Horn Speakers.
Hi @kennymacc ​​​​@james633 I think it is possible to make an analogue active crossover for Jubilees. But it will not be as easy. Time delay can’t be done like in DSP. But I have a friend who builds DIY speakers with and without horns with passiv... 
JBL K2 S9900 vs Klipsch Heritage Jubilee Horn Speakers.
I have chance to listen Klispch Jubilee on Montreal Audio show last year. The sound disappointed me. I think the reason was because the speakers were powered by TEAC amplifiers that are not a good match for these speakers. IMHO when I think about ... 
Capacitor replacement for Jamicon 25 volt
I can recomend Cornell Dubilier capacitor 383lx series. They sound good in power supply and have a huge number of voltages and values. Nichicons are good too. I also agree than 63v is better than 25v if there is enough place in box. 63v from the ... 
JBL K2 S9900 vs Klipsch Heritage Jubilee Horn Speakers.
I feel sad that most new 12", 15" drivers developed by JBL, Tannoy and other companies are designed for high power transistor amplifiers. One exception is Radian Audio. For normal home listening in a mid size room don't need heavy cone 15" drivers... 
Amplifier Pairing with Coherent 15s
I double checked. On Montreal show last year Allnic Audio M-2500 monoblock power amplifiers derived Coherent model18 speakers.  
Amplifier Pairing with Coherent 15s
Hi @mmcgill829 , Yes. To my taste this room was the best on this show. I liked this Coherent Model 18 room sound 2 years ago with the Allnic Audio T-1500 integrated 300B SET. A year ago Model 18 was drived by Allnic Audio monoblocs. It still sou... 
Amplifier Pairing with Coherent 15s
Hi @bjesien , I heard both at Montreal audio show. But in different rooms. I will not comment Devore. I think it was a bad match with amplifier. I liked Coherent model 18 a lot. I think this room was one of the best. These speakers are so diffe...
