Hi Peter,

Took me an hour & half to install the upgraded oscillators. It went of smoothly thanks to the detailed instructions sent by you.

To all the guys who are still with the older oscillators my advice is go ahead with the upgrade. The SQ is significantly improved. There is a lovely warmth to the SQ & the musical quality is excellent.

Regards,

Arvind

Hello Peter,

could you send me the instructions for a diy upgrade. Depending on selfconfidence, heat, Tour de France and other factors I will after reading decide to either try it myself or make an appointment to visit the home of the NOS1 Dac once more Happy

After three failed attempts  to send the new oscillators by Dutch mail (there are some very keen audiophiles among the dutch postmen) I finally got hold of them by visiting the x Fi fair in Veldhoven and receiving them in a nicely wrapped package personally from Ciska and Peter.
Starting with the extensive but also slightly intimidating instructions I went ahead.
Allthough I managed to get one of the legs unsoldered from the first oscillator (pff, just keep up normal breathing here, oi oi oi, stay calm , don't grab an axe and destroy the tiny enemy) I got everything installed and sorted out. 55 minutes from start to finish.
And presto no fifo errors and even better sound.
