Upgrade from Wyred 4 Sound STP-SE

Hang on to your STP-SE and get the upgrades done..circuit wizard Chris Johnson, former founder and President of Sonic Frontiers, is doing major upgrades to the STP-SE for Underwood HiFi, the only authorized retail dealer for Wyred4Sound. The complete upgrade costs $ 750.00 resulting in a richer, fuller midrange with more body and weight,
deeper, tighter bass, and smoother high frequencies.
Contact Wally to get all the details.

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.

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?
