Hi ack
Good question.
The reason for not choosing a recent version is the components of SMD topology. It is not easy to upgrade, this has several reasons. De-soldering SMD components and soldering again a new component, there is always a risk of damaging the printed circuit, even if it is of high quality.
After choosing certain components, they always have larger dimensions, for example capacitors. This was one of the reasons for my choice for this model.
I recently had a spectral preamplifier for a possible purchase, the classic DMC20 series II. I saw a potential in it in case of an identical upgrade DMA150, but did not advance. First, there is no remote control, then I didn't want to have two boxes, pre / power.
Possibly the choice would be the DMC30SL, it has the DMC20 II board and has remote control, this only in a box. The main update would be the volume potentiometer, the same to the latest series, then it would be the same as the one made in the DMA150.
I currently have a Wadia 6 that I bought in excellent condition, incredible that does not have a risk. I am doing the same upgrade, but this one is more complex and many upgrades come from my professional sector (recording studio maintenance). The clock, reclock and power supply is designed for this unit only. I have many CDs and about 90% are from Japan and the USA. This unit is only used as a transport, the internal DAC is removed.
Possibly I can open a topic here, I think many people might like.
