A good Preamp for ST70

Don't skimp on a preamp. The ST70 is a far better component than most realize today. Using something too downmarket will show up as the obvious weak link in the chain, and hamstring the ST70 from giving you all it has.

The Audio Electronic Supply (Cary) AE-3 is a superb choice with the ST70. A sleeper, if you can find one as they're quite rare, is the Vacuum Tube Valley Ultrasonic. The AES offers remote control, the VTV does not.

Both sound good no matter they're used in budget or far more upscale systems.

Shay123, I have seen several pas 2 and 3s here on agon but i wasnt sure of the sound quality although I have no direct experience with them. I think I will pick up the next one just to see. Hey Hoopster, great idea. I have a SS Jolida I could try. Might not meet the look I was wanting. I want to have a vintage look. Looking to add a set of Klipsh horns. A departure from what I have now. Trelja, I was looking at wright preamps as well as the Cary gear. It sounds like you have experience with Cary. What about Wright?

I do not disagree with Trelja who has probably forgot more about tube amplification than I know. I think he is very much on point when he says the ST70 restored and upgraded is a very under appreciated piece of gear. However, I can tell you the sound through the Grant made me sell my CJ PV10 (which I have loved for many years) because I felt I did not nead it any longer. I bought the Grant as one of those I am going to try this thing moments and after living with it decided it was the way to go for me. Got a decent sounding DAC in the deal also, not state of the art but very pleasing. In the immortal words of Newbee, YMMV.

The Grant does not give you that classic tube look though. Another consideration might be a Mapletree pre which I have never read but only good things and want to try at some point in my main rig. I have a TAD 150 Signature there matched with a TAD 60 amp there which are very synergistic IMHO. (I tried a PV14 there but ultimately liked the TAD pre better.) Also the George Wright pres show up here from time to time. These may be a consideration. Again, I give these considerations with the disclaimer that I have not heard them either. Only putting forth these because they seem to be well thought of. I have not heard the Cary/AES Trelja mentions or the other one but I am sure they are solid choices.

We've rebuilt and updated a lot of PAS-3s and PAS-2s over the years- given it a new line stage, better parts, power supply regulation, stepped volume control and the like.

What's fun about that preamp is that if properly updated it can take on any modern high end preamp and give it a run for the money (of course it will not handle low output moving coil cartridges, but with a set of Jensen SUTs, you can manage that quite well too). Since you already have a modified ST-70, it might be something to consider.

I used an inexpensive passive (Luminous Audio Axiom) with a set of Will's rebuilt MKIII mono blocks. The sound was just incredible. Single source only, but it sounded f-ing great. I still have the pre in my closet as a backup.
