What is difference in the sound signature?
Top resistors
My interest in the topic increased after recently installing the latest Texas Components nude Vishay TX2575 in several SS and tube phono & LS components. This was a proverbial "Ah-ha" moment-- a stray resistor dropped into signal path here or there, surprising with an improvement that equalled or surpassed the impact of a switch to a top coupling cap like V-Cap or Mundorf.

I built n-1500 crossover for Altec 604E. DIY Altec N1500A (audioheritage.org) I use constant resistors instead of potentiometers 36 Ohm and 7.5 Ohm. I also use resistors 1.2 Ohm - 1.8 Ohm for super tweeter crossover. I tried Duelund Regular and Custom, 12 Watt Mills Black and Brown and 20 year old Dale CW-5-500 5 Watt. Dales are worst not smooth not transparent. Both Mills are very clean and transparent but a bit bright and not very natural tone. Mills are best in term of focus. Duelunds are best. Natural tone and more calm, less ringing vs Mills.

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 single Duelund Custom 7.5 Ohm resistor. The difference is huge! On first glance, Mills-Duelund combination sounded transparent on simple music. But on complex music sound become congested, messy and unpleasant (the same was happened when I used 6.8 Ohm single Mills resistor before). I don't understand why most of audiophile call artificial, synthetic, mechanical sound "neutral" ? |
