Hi and thanks for bringing this up. Ultimately it IS a matter of cost. I won't go into all of it, but obviously we have a dealer network and so every part cost has a non-trivial impact on the retail price.
At the $5K price of the LS 36.5, we used the very best caps, Teflon tube sockets, tube-rectified supply with more MWI caps, custom remote and high-end chassis/machining, custom-wound output transformers and an innovative tube circuit.
I did experiment with the DACT attenuator in the 9.0SE vs. the Alps and heard SOME improvement in ultimate detail/resolution, but I found the improvement to be relatively small and didn't want to give up the R/C capability. Admittedly, we could add a stepper motor and DACT attenuator, but this does drive the price up exponentially, believe it or not.
I honestly feel that areas such as power supply design and other direct signal path components have a greater impact on the overall sonics, especially with respect to overall cost/value.
I do try to always produce products that represent extremely high value, no matter the price-point. How many other mfrs. offer a $5K product with custom capacitors and Teflon tube sockets with the build quality of the 36.5?
We will undoubtedly offer higher-end products over time and there are things that can be done, if cost is no object, but I will always keep performance/value ratio as the top priority for each of our design considerations. I.e. every design decision that we make that significantly impacts cost, is weighed against what I feel its overall positive impact on the unit to be.
I feel that the Alps Blue is a very respectable choice for a volume control and it is one of the few good solutions that allows for R/C capabilities also.
Thank you very much for your input and feedback.
Take care,
Dan W.
