@bigKidz My mistake, you indicated that you received only ONE comment concerning Lampizator upgrades.  What upgrades have you done to them other than tube rolling?

@fleschler most of the upgrades in general are in the power supply section.  Upgrading to nichicon or audio note capacitors.  Then signal path resistors mostly amtrans or audio note non-magnetic resistors now.

Tube rolling is not a upgrade we perform.  Our DAC and preamp began as 101D direct heated triode tube products.  Lampizator was not even offering that sort of product.  I do not remember what Grover secret sauce was and I don’t believe that most products we repair/upgrade/modify are not good sounding.  They just can use a little benefit from the better parts.  We only change the design for products that are in very bad shape and have burnt circuit boards.  For the Da Vinci, that was a real mess and we had to fix other repair techs work.  We were the only ones that got that unit to work.  We also repaired an older Art Audio stereo amplifier that nobody else could repair.  Again I will say that my business partner has a masters degree in electronic design.  He has been doing this since he was 10 years old.  How many people can say that?

I don’t remember the person who posted about his Lamp upgrade.  Don H (not sure if I can post his last time without his permission).  But the power supply and some resistors were upgraded with better parts and that upgrade produced fantastic sound to his unit.  We were impressed with it.

We also did a Cary SACD/CD players maybe 306S.  Over one hundred parts we swapped out if I remember correctly.  We did this for someone and the results were so great, I purchased the same model and upgraded it for myself.  So we are always learning and wanting to improve our own sound.

Thanks for posting.

@bigkidz Again, you did not answer what piece of GroverHuffman equipment you worked on.  I will calling him later to find out if he or his friends know of you.  He is very careful to choose NOS high quality capacitors and electrical parts throughout his units.  Maybe you replaced a knob or toggle switch?  Funny you mention Art Audio as those pair of old monoblock amps for about $20K are probably similar to the one’s Grover restored perfectly several years ago after they were abused and run down (looked trashed).  He is so smart he filed and received a cable patent without an attorney, without a college degree either.  He has been building and repairing electronics for about 40+ years (he was also a professional photographer/developer/printer prior to audio electronics).  He also can repair motor vehicles, household appliances, etc).  

What Lampizator piece of equipment did you work on?  Was it a DHT model or a recent non-DHT model?  

What model and what type of work did you do on a Jay’s Audio transport?  If it wasn’t a transport, I’m not familiar with their other equipment.  

Cary equipment could use some work.  I never heard or met anyone with a Cary DAC.  

I’m 100% certain that you never worked on a Westminster Labs product.  Or Trafomatic.  

@fleschler not sure what you want from me here.  I'm looking for input on launching my business. Do you want me to list 25 years of repairs upgrades modifications?  The Cary wasan sacd 306S if i remember correctly. The lamp was not a heated triode model.  The other stuff is a blurr.  The last two items you mention no. What dies any of this have to do with anything I'm looking for input on?

It doesn't...
