Well upon researching I just stumbled upon these modern Vishay TO-220 case style resistors. Interesting and high wattage. And I suspect lower overall Z. I wonder if the sonic results would be better than the aluminum cased milspec, or classic sand wirewound types. Being for the topend they might be the ticket.
Any thoughts of ideas are most welcome. In fact if anyone knows what sonic differences exist between the classic sand type and the aluminum housed modern wirewounds? I’ve yet to experiment with these so I’m officially ignorant on the subject.
Nevertheless check these Vishays out.
