I have both a Don Sachs phono stage and one of his preamps. The preamp is probably an early model, one of the first with remote.
Both are superb.
Because of the pricing of Don's equipment there is a tendency to add "for the money" to review comments.
While it is true that Don's gear costs less than some comparable equipment that should not be the driver of the buying decision.
For instance, I also have a Pass XP 20 preamp which cost, new, so much that I would rather not say in case my wife's people are monitoring my Agon activity.
I keep both preamps because I like to change the sound of my system now and then....my wife still works so I can do this during the day and she does not notice.
Is one better than the other?
All I can say is that they are different. And that I am glad I am lucky enough not to have to make a choice.
I will say that Don's preamp is by a large margin the best tube preamp I have had in my system, and I have had a few.
Don is a class act, always found him to be helpful and straightforward and goes out of his way to help a customer. I have asked many stupid questions, sometimes about equipment other than his own and he always takes the time to answer.
