No! In the end, I took it to Roksan who upgraded it to the MkII spec, and also replaced the laser unit. It has performed faultlessly since, including playing CDRs. If you are still struggling with a MkI, I'd say let Roksan upgrade it for you.
High frequency roll-off optimised to be completely smooth into Mhz range
Extended frequency response at both ends providing tighter, deeper and faster bottom end, naturally open mid-band and crisper yet smoother top end
New on board power supply section improved with far better high frequency noise rejection and dedicated regulators for the new output stage amplifier
The new output OpAmp with improved current drive
I'd say the upgrade IS worth the cost.. its much cheaper than buying a new player and the improvements are noticable. Would have been nice to compare a MkI with a MkII side by side to see exactly how the sound has changed, but to me it seemed immediately 'fuller' and 'warmer' whilst still being super sharp. Its interesting playing some early CDs which aren't mastered as well.. I never realised just how poor some sound!!!
Hope this helps, let me know if you want more info.
The current cost for Roksan to upgrade the CD player is £345. For this they will upgrade the CD player to latest M series spec, the model that superceded the Mk2. They don't replace the face plate, so it will still look like your Mk1, but sonically will perform like a M series which currently cost £1100.
FYI, if you have other Roksan components, it might be worth you joining their cognesciti club. It costs £100 to join, but for this you can get your Roksan kit serviced for nothing, and 20% discount on parts and upgrades.
So the cost of the CD upgrade would be £276 plus £100 joning fee. So you will end up paying £376 for the upgrade and club membership - an extra £31 and for this you can get your amp serviced for free.
I tried to book my CD player in recently, but factory is closed for a fortnight.
