I owned the Freya Plus for 2 years, and currently have it posted for sale on USAM.
If you want to save money ($650), please feel free to consider my listing.
Putting that aside, here are some thoughts for you to be aware of (also discussed in my listing).
First, with the right tubes, the Freya Plus is a top tier preamplifier (not best of the best, but can compete with preamplifier on the lower end of that top tier), which is unbelievable for the price.
Two, I bought mine with the premium Tung Sol tubes. After first listen, I was prepared to sell it the same day. It sounded dry, sterile, and no dynamics. I switched out the Tung Sols on the output stage, and replaced them with the Electroharmonix Platinum Cryo-treated tubes from Upscale Audio and it completely transformed the sound... huge changes...honestly...from hell to heaven and those tubes are inexpensive. My theory is that the Tung Sols are really good at filtering which is why they work so well when left in the buffer stage, and sound so poorly when placed on the output stage.
A PS Audio BHK Signature preamplifier replaced my Freya Plus, and the Freya gave it a good run for the money soundwise using the stock BHK preamplifier tubes and the magical pairing of tubes mentioned above. I bought some new tubes for the BHK and expect those to take SQ to the next level.
Hope this is helpful and best of luck.
