Are some of the ultra expensive Phono Pre's using resistors like those?
I bet not.
If you are building your own boards as Nick77 is, I would think about it. It is a dual mono design with a Gary Dodd custom power supply. He has got it done maybe he will share his experience with it in the vinyl section. I sure would like to hear it.
I do not think it necessary going that high $ in the Vista.
It is "fast, clean, and neutral" I'm going to leave well enough alone.
I have a mass amount of choices here now.
Still, you think what if..........
I think a couple of them are using nude Vishays. Some high end units have sealed modules so you can't see what's inside. This is done mostly to keep other companies from stealing the design, really. A patent that's worth anything costs big bucks and other companies will steal it anyway and fight it in court yrs later. The consumer electronics industry is ruthless in that respect, as is most big business. So an ounce of prevention... I think this started with Mitch Cotter in the '70s. He used to seal all his electronics in what looked like expanding foam. I had a Cotter SUT that had little silver jumpers in the side of the unit. You could resolder the little jumpers to configure it for different gain and impedance. It had captive silver cables coming out, and the inside was completely sealed.
The AHT Non Signature phono stage was the only 5 star component in TAS for something like 3 yrs running in the late '90s. The TOTL sold direct for around $5K, not really expensive by today's standards, but if it went through dealers it would have been close to $10K. You could see where the money went though, it had teflon boards with silver traces. A couple of caps on each channel were teflon and the plug in resistors for load and gain were the encapsulated Vishay they used in the space shuttle. The regular version of the IC, 3 per ch, cost $30 ea today, but the military version was used, at least for the one handling the signal. The power supply had a hugh toroidal transformer which could power a pretty big amp. My AHT isn't the TOTL, but I have the teflon boards and caps and a big power supply with regular Vishay 102, I think they are. Those are the ones I substitute sometimes. When the AHT designer got out of the audio biz, he had offers from Herron and Walker to buy the design. He sold it to Walker and it now has a DC offset circuit and sells for $14K.
I have no idea what Nick77 is building, and I don't really know how much difference a nude Vishay or a space shuttle resistor would make. They are super stable in all kinds of temp, if the music puts you in space.
My suggestion would be to save the money and get more records.
