well, it's been a lot of years since i've used joseph chow's services, and i had very good results.  15 years ago, he converted a japan-spec acuphase t109 for me, and upgraded it as well.  the work was very good.  a couple years later, i had him convert a japan-spec sansui tu-x1 for me, he also upgraded it.  again, i was pleased with the work.  in fact, a couple years later, when i started hearing audible crackling noises in the audio output, i sent it back to him, and he replaced aging caps that were causing the noise.  i was only out the shipping costs to get it back to him.  no, i did not have him go through the entire tuner, replacing everything the 1st time around - i can only imagine what it would cost to do that to a tuner like the tu-x1.

perhaps his efforts have diminished more recently?  i would suggest reaching out to him directly with any issues you may have had.  in my experience, he always tried to make things right.

Unfortunately, I too have had negative experiences with Mr. Chow's work. A few years ago he sold me a modified Music Hall mmf-25 CD player, supposedly having upgraded parts and enabling it to be used as a digital transport with an external DAC as well as a stand-alone CD player. As a CD player, it worked for a while and then lost output to the right channel. I took off the cover and noticed a small component that he added had become unsoldered at one end. A local repair shop was recently able to resolder the joint for me at a cost of $50, but when I try to use the mmf-25 as a transport, it doesn't work at all. Add to that the difficulty I had getting the unit in the first place (requiring threatening him with a bad review on Audiogon before he finally shipped it to me), and I too cannot recommend his "upgrades." I'm only out about $400 altogether, and the CD player works as such, but I would not buy equipment or services from him again. Your mileage may vary.
