Top resistors

Audiotweak, please post your findings regarding TX2575 vs. TX2352.

I'm bumping up this thread as I just completed a comparison of resistors in the gridleak position of a tube pre-amp.

The contenders:

Vishay S102C
Tc TX2575
Dale RN65
Takman Rey
Shinko Tantalum
Holco (old stock)
Caddock USF340 (TF020)
Generic Metal Film
PRP

This was quite an interesting undertaking as I was not expecting to hear drastic differences. In the past I heard differences between resistors but mainly in the high frequencies (cartridge loading application)

The Shinko Tantalum was by far the most inaccurate resistor of the lot. Dale RN had the most bass and midrange warmth. TX 2575- the biggest disappointment of the lot. A laid back/bland/lifeless sound. S102/PRP/Takman/- not worth the time of day. Holco- now this is an interesting part. Very lively/dynamic/textured presentation with great inner detail and prat. Unfortunately it adds a fullness to vocals and mid-bass that ultimately becomes distracting.

And the winner......by a w-i-d-e margin is the Caddock USF340 (TF020). Clearly the most transparent/musical/involving resistor I've had the pleasure to hear.

Very interesting. It's been awhile since I made the comparison, but for me Caddock TF020 is a close second to TX2575. IIRC TF020 was initially strident on top, but eventually settled down. Nothing bland about TX2575-- just clean and clear.

Reb1208, thanks for your impressions!

What were your thoughts on the PRP?

PRP- Incoherent, unrefined, opaque with an emphasis on frequencies in the upper mids > lower treble.
