Sonic Frontiers Line 1 valve preamplifier SE and Balanced plus Loop
Superb pre for sale, selling due to a change of plans.
Great headphone stage too.
In stock form these are very highly regarded. This unit was upgraded by Parts Connexion in Canada which is owned by the ex-founder of Sonic Frontiers so the work is done by someone who knows their stuff and the circuits of these units.
The pre has been max'd out and sounds incredible - very very revealing. Leans towards the cooler sound of what valves can offer.
Comes with the puk metal round remote and works like a dream.
4 x single ended inputs
2 x balanced inputs
2 sets of single ended and 2 sets of balance outputs
Tape loop
Upgrades:
Tubes:
4 x NOS matched Tesla gold pin E88CC
2 x NOS matched 6H23N-EB Reflektor ultra low noise military spec, ruggerised
Power Supply:

12 Diode upgrades
Resistors now Kiwane (5)
All electrolytic caps upgraded to various Nichicon's
Hi-Fi Tuning Silver Star fuse

A lot of labour

Volume gains in 0.5dB steps making getting the perfect volume spot easy.
Demo welcome.
