Hi guys, I have had the Arcam 170 CD transport for yonks , it was bought AFAIK when they first came out. I added the Arcam black box but after a couple of years exchanged this for the Deltec DAC, the Deltec is probably 6-8 years old now. I am no techie but have read a lot here about the benefits of a good CD transport coupled with a good DAC and wonder what I should do re upgrading. Should I look at upgrading the transport or the DAC? Partnering equipment: Pair AE1 V1 oldies but goodies Arcam AVR200 receiver, I will probably add an Arcam power amp to power the woofers on the AE1's leaving the AVR200 to power the tweeters and the other speakers when in surround mode. Mission Radius centre, surround and sub. Any thoughts/advice much appreciated.
