Thanks Bob, one point regarding fans and power supplies. . I agree good DC supplies are beneficial and am opposed to fan noise, but by combining the 2 you can get the benefits of fans without the noise. Heat is the enemy of electronics and just a small amount of air movement can make a huge (20-30 degree F) difference with some devices, verified with an infrared non-contact thermometer

 

Get some very low noise 12 VDC computer fans then run them off of a much lower voltage from a DC supply. 5V is probably not enough to get them spinning but 7-9 V will. They turn slowly enough to create no noise but move enough air to keep things much cooler. Pop the lid on a DC supply and point the fan at the regulators and you might be surprised how much cooler they run... like these

have one fan I have been testing it is a Noctua NF-A14-ULN.  This is a 12v fan that is not PWM a

 

pretty sure the fans have nothing to do with being or not being pulse width modulated. That is a function of the controller. PWM is a highly efficient way to control the fan speed but the fan doesn't care. If you take 12VDC and pulse it to the fan at 50% (12 - zero - 12 - zero ) with an electronic switch (transistor) you  effectively get 6 VDC as far as the fan is concerned but no heat because the switch is either full on or full off. If you use a linear regulator that drops 6V all the time you get heat. Unfortunately with PWM you also get electronic noise.

please don't throw things at me,  in my experience properly constructed digital cables do not affect sound quality. Geistnote makes high quality , professional grade cables found in many high end studios. They are properly constructed, well, built , and reasonably priced.

feel free to trash me but I do not care to debate the topic
