Supratek or Don Sachs - which way to go?
Hi all,Don Sachs here.   I just want to clear something up.  Yes, you can buy a kit from Roy and build a great preamp.  I use the same board.  I suggested a number of improvements to that board and now kit builders can have them.  That said, my pr... 
Don Sach's pre amp
Hi all, I have modified the preamp to take a 6BY5 rectifier because it sounds better and you can source 6BY5 tubes for $12 or less. If you own one of my preamps and pay the return shipping I will modify it for you and provide a 6BY5 tube for $7... 
Don Sachs 2 vs. deHavilland Ultraverve 3
The par metal ones because they are in New Jersey and you can get most any sizes.  I don't think they manufacture there though, they just stock parts.  Maybe I am wrong.  Anyway, you can get a cheap case and then have cnc panels made for $125 or s... 
Don Sachs 2 vs. deHavilland Ultraverve 3
I have thought about it, but it would be low powered, probably el84 based or 6V6, and 15-19 watts/ch.   The problem is that I cannot fit the best line stage and the best power amp in any sort of smaller case so have thought about compromises that ... 
Don Sachs 2 vs. deHavilland Ultraverve 3
Hi All,A customer pointed out this thread to me.   I will just say that I have improved the line stage by about 10-15% in the past few months.   I have gone to a different output cap, a Polish made Duelund copy that is just mesmerizingly good.   A... 
Are there any $1500 tube preamps that that can compare with Tubes4hifi's SP14?
HiDon Sachs here.  I am not trying to sell anyone anything and don't want to violate any of those sorts of rules so I will give my opinion.  I have built and sold over 40 custom preamps built around the sp-14 board.  My opinion is that if you take... 
Seeking Suggestions on Preamp Upgrade (CJ, Aesthetix, EAR)
HIDon Sachs here.  I see I have been talked about.   I would love to build the OP a preamp, but he has an amplifier with a 15K input impedance.  I could certainly use a really large output capacitor value and drive that load, but it has been my ex... 
Review: Space-Tech Lab VP-1001 Tube amp
HiI think that Albert has a pretty strong following even if it isn't too large. I emailed a few people to check him out when I was considering his equipment and everyone felt that he had built them wonderful gear and had been a pleasure to deal wi... 
Jolida reliability? Anyone with comments?
Hi,My two cent's worth... I have had a modified Jolida JD-1000a integrated for a month that I bought on Audiogon from "underwoodwally". I biased it when I got it and just recently replaced the stock Chinese EL 34's with some Siemens ones so I have...
