Upgrade from Wyred 4 Sound STP-SE

Black528..more than likely your aware of Sonic Frontiers and their remarkable tube electronics back in the 90's which included the Power 1 Amp and their Line 1 Preamp. Their CD players were tube based as well. The founders, Chris Johnson and Chris Jensen are tube guys. I suggested getting your STP-SE upgraded by Chris Johnson, and more than likely his mods would bring the STP-SE much closer to sound like a tube Preamp which you want to achieve.

I went from a W4S STI-500 (some of the same circuitry as the STP-SE) to a BAT VK-52SE with Hypex NCore's for amps. IMHO, I strongly disagree with the description of BAT being labelled as overly DARK or a WARM LAYER OF CARAMEL.

To be perfectly honest though, I think that for the price differential over the STP-SE, you are going to only get a small improvement in performance with ANY pre-amp.

Mine sounds perfectly neutral. I cannot tell how much of the change is coming from the new amps and how much is coming from the new Pre-amps, but overall, my system went from sounding excellent to superb.

I think the only way you are going to find out is to try one in your system. I think if you find a good deal on a used BAT or ARC unit that fits your needs, go ahead and get it and if it doesn't work out for you, you should be able to resell it for a similar price meaning you will only be out shipping costs.

Another one to consider would be the Modwright. I had it narrowed down to that one and the BAT and found a better deal on the BAT before the Modwright. I am perfectly happy with the sound of my system now and am not planning on upgrading/changing anything currently.

Merlin:

Glad you are enjoying your system. I just wanted to make clear that I did not say "Bat" in general had the characteristics I discussed. I spoke specifically of the unit I had :) the Bat Rex. I can not speak to the VK-52SE :)

If you can find one used, I heartily recommend the Von Gaylord LAD-L2 at relatively little additional cost to you. I used to own the STP-SE, then a Conrad Johnson CT5, and have had the L2 much longer than both. It has a lot of that vivid, soul-reaching tube magic but is also very detailed and clean, but not edgy. There is not a whole lot of info about it out there, but it's there, and you'll see that it is quite beloved by those who've experienced it.

Has anyone taken the plunge and purchased the STP-SE Preamp with the Level-2 upgrade from Underwood Hi-Fi? Wally at Underwood informed me recently that the Level 2 upgrade done by former Sonic Frontier's engineer Chris Johnson puts the STP-SE on the same performance level as the Spread Spectrum Ambrosia Preamp that Underwood also sells. Wally stated that the upgrade is 100% as good as the Ambrosia which has been compared to Preamps costing well over $20K. If purchased new, the STP-SE level 2 upgrade will cost you an extra $1200.00 or $1400.00 if you already own one. Curious if anyone has listened to the Level 2 upgrade version and is it as good as Underwood says it is?
