Top resistors

In the past I have built bridges made up of many Vishay resistors for replacement of high wattage resistors in loudspeakers..Upon first hearing this change out tears may arrive in your eyes.

All those engineers and designers who say there are no differences in these parts either have a problem hearing the truth for themselves, never listen to a simple part swap out or just sell their product based on external appeal. Tom

The Vishays arrived and I installed them in the 6C6 cathode position. Will report back in a week after some burn in time

After 60 hours the the Vishay TX2575 are starting to sound really nice. That crispness that the AN Tants had in the hi frequenies that was bothering me is not present in the Vishays. The high end seems very natural. So far there is richness, natural detail and some soundstage depth. I do notice paticularly how natural they sound. Very satisfying in that regard. They need to develope more front to back depth for me to be completely happy.

Before 60 hours, they sounded sterile and intruments didnt have their individual tonal characteristics. The soundstage lacked the depth and richness of both the AN Tants and A-Bs. I was not loving the sound at all. Sound stage was flat and uninteresting.

So far so good. More in a few days.

There is a lot to consider in my opinion when choosing resistors. Is much more than just making sure they will handle the power.
When it comes to noise, there is nothing better than high quality wirewounds such as Dale RS or Mills. You also want to use a larger physical size in areas that can be prone to noise. No problem using a 5 watt where a 1 watt would work. It can make a difference.
There are certain applications where a certain type of resistor is better suited. Unless going for a vintage sound, I stay away from carbon comps anymore. They are just not reliable enough and can drift in many applications. I wont even use them at grid stops.
There are some very good metal films available today as well as some decent carbon films.
Resistors can make a sonic difference depending on how and where they are used. I would certainly not used sand cast resistors in the signal path just as I wouldn't place a carbon comp in the power supply.

Sorry for late response, but I like the AMRG in my active crossover....to the debate on coloration, you have to try to hear for yourself.....especially if you find the AN tantalum to have none....
