Welcome to AC. All those preamps you listed are great, tough choice. The Sachs allows you to customize to your tastes. Give Don a call and tell him what you are looking for. I spoke to him last year and almost ordered one but decided to keep my BAT. As far as CJ I would look at an ET-5 (instead of the CJ-5) and there are a few for sale on Audiogon used for good prices as the new ET-7 is available.
For dac's take a look at PS Audio Direct Stream, a very detailed and versatile DAC with multiple software packages so you can tailor the sound to you liking. The T + A DAC8 is awesome if you use HQ player and upsample to DSD512. Others to consider are the Auralic Vega G2 and Schiit Audio Yggdrasil.
