A little bit of help. I have had a DX50 and now have a DX90, which I most often run coaxial into a Chord Hugo2. I am thinking of upgrading the DX90 to either a DX200 (used) or a DX150 (new) as both are a similar price. I would then use the new machine on my travels as a stand-alone unit rather than linking it to the Hugo2. On my p I use SE846s. Intuitively I think I will prefer the warmer sound of the Dx150 plus Amp6 versus the DX200 plus Amp1. I really like my DX90 but I fancy an upgrade but given I generally use it coaxially now via the Hugo2, will I be satisfied with the sound of the DX150 or DX200 vs Hugo2 My questions therefore are : 1. Sonically how big an upgrade is the DX200 & DX150 above the DX90? 2. Which one of the two to go for ? The DX200 is presumably a more refined machine and has 2 SD card slots but has it other advantages ? the DX150:is a newer machine. Any thoughts welcomed.
