I can think of other reasons why people might say the knob makes a sonic difference......

I was initially worried it would sound too 'silvery'. The combination of rohs compliant solder and the plating had me worried, initially.Thankfully, so far, it is not and is calming down nicely. Dynamics are improving.

It is being used in one of the most demanding situations possible - a passive preamp.

WBT nextgen RCA's, a maximally damped chassis, and er, VERY unique wiring. . It is 'possibly' the most resolving of passive preamps in existence at this time. There are sound and solid reasons for that, which I won't get into at this time. Apologies......

Many thanks for the pics and impressions.

"calming down nicely" sounds like famous last words before delegating a component to a dark drawer hopefully not what you mean

Any idea how it compares to a Shallco?

I wish I knew. Send me a Shallco and I'll let you know.

I'll need a year for both to break in, of course.


Now for the SMD (surface mount) 50k ladder MBB units that arrived yesterday.

Looks absolutely great. Are you going to keep the lead out wires? It may also be interesing to investigate the contribution of the pretty cover.

I'm liking the sound of the Dale resistor ladder unit, so far. It's been in daily use since the first day I reported on it. It is, of course, a case of randomly using different settings and hoping I'm hitting enough of them and using each long enough...that most settings (resistor pairs and associated contacts) are breaking in. The pot is 'on' and passing signal 24/7.

Hi, I am new here ...
may I ask if there is any apparent advantage in using SMD (surface mount) resistors over the non-inductive Dale ? I mean in ladder attenuator, please advice me, thanks.

The point is literally debatable and such long and torturous debates have emerged here on this forum, so you should go and search for those threads. This thread is centered around being a discussion on the availability and sonic aspects of this particular attenuator.

Apologies.

Does he give a rotational life span on that wiper? What is the wiper arm made of?
An all PRP swap might be interesting...
