Yes the bass really tightens up. Drums should be fuller, treble more natural and the soundstage just huge. Will wait a couple of weeks before I really sit down for a critical session. House sitting at my sister's next weekend, so will be another 300 hours on from now. Plenty of time to find my impressions of it all...

Yes it is pretty impressive what it all does. It is a really big step up and for me just makes the music flow better Don't forget that you have a different clock upgrade from me fitted, which doesn't require burn in, but more of a warm up till it hits its operating temperature. That normally only takes a few minutes on an average day. But I have noticed that it can take up to 10 minutes now that the weather has gone a bit colder.

As has happened before for me, anything designed by Stan is joy. Plays way above its price, allowing the music to shine. Many thanks to you Mr Beresford.

I would like to qualify the clock running in process
this is not the clock itself but the regulation circuit around the clock which has been designed to deliver a very quiet, clean and steady voltage supply
the regulator section contains some special ultra low esr and high ripple current capaitors which are capable of handling far greater current and voltages than clock itself requires these take the time to fully bed in as the current the clock uses us between 15-50 miliamps it will take a long time for this happen and the capacitors settle down this has been well documented by many customers over the years
however the results are more than worth the wait, the regulator circuit in an aftermarket clock is as important as the clock it self imho which is based on close to twenty years of working with digital circuitry and hands on experience with over 250 aftermarket clicks fitted
yesterday John popped round for me to sort out a potential problem for him, which turned out to be indicator lights not sat back in their correct holes!
John felt like our QP1 power supply possibly was at fault with his new streaming from end the specs read around 2amps @12vdc.
i spent sme time re-engineering the voltage stabilisation circuitry and now have upto 6amps stable @18vdc (heat sink dependant as well)
anyway the upshot was we also measured the actual working current the SEG uses around 250ma very briefly on a cold start up then settles down to around 100ma at ldle and 130-160 with spdif or toslink with USB it uses more due to the revived chip and associated circuitry it goes up to around 200+am which on the grand scheme of things is not a great deal
Johns new streamer actual uses around 650ma at cold start up so we were well with intolerance but now with the supercap and voltage reconfigured fitted for his SOTM John is now reaping the benefits
While checking out the current I also performed some further upgrades to the SEG to make full use of the clock and firmwhete than Stan fitted

Each of the LEDs can be pushed in our out till they are flush with the front panel. It's possible to push them in accidentally or otherwise with a finger. But to push them out you need to open up the case. I used to glue them in on earlier DACs, but then it became a bit of a mess to remove the PCB from the case.
