DK Design VS.1 Reference mkII - Optimization


I would like to know what tuning, customizing, hot rodding, tweaking, what ever.. that you owners of DK Design VS-1 MK2 are using to bring out the best in this amp. It seems to be responsive to changes in interconnects, tubes, power & speaker cables, speaker dynamics, etc. most probably to both the positive and negative.

Please share your work. I would like to know what improved it's performance, what caused no real change and what made it sound worse. Thanks in advance!

This is incorrect information.
John Tucker is Vice President of Operations of LSA Group.
This is not a mod, but a collaboration between John and myself for the improvement of the original design.
I don't know how rumors like this become so convoluted, John has worked for us for about a year now, and brings a remarkable technology with him.
These are stock units, that being the Reference, all QC'd by our Seattle facility, John's facility, then an upgrade to the preamp section only, the Signature Edition, with the final upgrade being to STATEMENT Version, which is a full exchange of parts in all areas, replacing inexpensive op amps, utilizing Active Tube Loads, stabilizing the tubes into the 4/6 MHZ region, generally unheard of.
This is definitely NOT a mod, but a factory recognized, and internal event.
Just so everyone understands the relationship, John IS a part of the LSA Group Team, brining his full expertise to the company. We are fortunate indeed to have him aboard.

To all,
Sorry if that comment, clarifying the nature of John Tucker's involvement in MY company ruffled Jomoinc's feathers--it's just that, with others actually modifying, therefore voiding warranties, I wanted to set the record straight.

The Amp's name will change to LSA in our next run--simply to make our marketing direction clearer. We have made significant product upgrades in the internal parts, and quality control since buying DK more than a year ago.
QC'ing all the amplifiers has been a great value add for most of our customers--since we include a certificate with each amplifier, signed by the technician performing the tests.

Our newer models, the Signature and Statement, are in the hands of reviewers as I write this, so we should have press shortly--also, Bound for Sound's Marty DeWulf reviewed the Signature some time ago--and was impressed with the sound, enough to compare it to units,(even separates) costing multiples of the price.

Thanks for the opportunity to clarify.

Best,
Larry R. Staples

Lauritsvd,
In what country do you live? There are other options than to send it to the USA. LSA has a European Master Distributor, if you live in the European community, for example.
