Why recordings made before 1965 sound better.
It is not just tubes vs SS. Before 1965 year record were made with a small amount of microphones, console schematics were much simpler with shorter signal path. The signal path become longer in number of times! And each addition electronic stage ... 
DIY Replacing Components in Crossovers
What kind of speakers do you have? What kind of drivers? How much money do you plan to invest? I just rebuilt my Altec 604E crossover using original crossover schematics. I just use original inductors. Capacitors in most vintage speakers are of v...

From the book of Geoff Emerick "Here, There and Everywhere". About a new SS mixing consol:  "As it happened, the first week of the Abbey Road sessions were quite peaceful without John and Yoko's presence, though  a bit tentative because of equip... 
Turntable upgrade recommendations: SME vs AMG vs Technics vs other
Sorry for my bad English. English is my fourth language. I think a heavy platter weak motor combination can work only in super ideal conditions. Even rubber belt compliance uniformity can be an important factor. Any deviations of speed in such a ... 
Turntable upgrade recommendations: SME vs AMG vs Technics vs other
Hi @lewm , Here is a bad thing about a spring-suspended DD turntable: The energy put into rotation of the platter is also going to twist the chassis on its suspension, in the direction opposite to platter rotation (counter-clockwise). EMT had ...

Turntable upgrade recommendations: SME vs AMG vs Technics vs other
Hi @mijostyn ,   Lenco Turntable is a genius piece of Swiss engineering. If you add heavy plinth and upgraded tonearm it over performs any mid priced belt drive turntable. One of my friends who had used dozens of great turntables used Lenco L70 ... 
Turntable upgrade recommendations: SME vs AMG vs Technics vs other
Hi @terry9 , Motor turns platter in jerks just in cheap DJ DD turntables like Technics 1200. Top Japanese and German DD don’t have this issue. For example, EMT 950 motor (DC PWM) works so smooth that is has super light platter. All lacker cutter...

I had a Nottingham Analogue Spacedeck turntable for many years. Then I switched to vintage Lenco L78 on a heavy birch plywood plinth. I was amazed how much more accurately the Lenco idler drive conveys all the nuances of the rhythm compared to Not... 
Top resistors
I did more comparison between Duelund Custom resistors and old "black" Mills in Altec crossover. In my case 7.5 Ohm resistor is connected to compression driver. At first I used 3.9 Ohm Duelund and 3.5 Ohm Mills in series. Then I changed it to sin...

Hi @mozartfan , 845 tube needs ~10KOhm output transformer that has more narrow bandwidth compared to 3.5K transformer for 300B, 5K transformer for 45 or 2.5K transformer for 2A3 tube.  So, if you have high sensitive speakers in a small room I do... 
If a " system " cannot do this, I move on........
Hi @mrdecibel , Yes it is very important point you are talking about. The system which help you feel interpretation. But sadly most of audiophiles don’t care about it as well about natural instruments tone. Probably, because that, low sensitive...
