C/L find a few months back. Needed a bit of TLC. I’ve been running this along with a pair of Nova 7B speakers on my office system. Incredible FM reception. Great match for the Nova speakers.

re: STA-850-UPDATE

A bit after I wrote the initial review, I gave the Nova 7 speakers to a co-worker and refurbished a pair of CV RE 30's. The combo sounded pretty good in my workout room
Over holiday break I installed new caps on the 850.. The filter caps were different from any others I've worked on. Instead of the usual larger two 6-10K uF caps (one each channel) these were 8 smaller 4K uF caps. The engineers who designed this had 4 caps per channel. All were glued together fairly well. I use Nichicon audio grade caps. Yep, I know a cap is a cap but for the extra $1 each it's not going to break the bank.
On most of the stuff I recap, I can tell there's some subtle changes for the better in the unit's sonic performance. Probably more implicit bias than actual sonic difference.
With the new caps installed on the 850 there WAS a noticeable improvement. In that room we stream Amazon Music on a dedicated laptop through an Audioengine D3 DAC. This bypasses the laptop's crappy headphone amp.
Even my wife, who usually doesn't notice things like this, asked me if I put a different receiver in the room. Told her no, she still thinks I'm lying because this sounds so much better than the 'old' one.
