Graham, going to a bespoke LPS on my Straingauge cart has been night and day, although the 100 hour burn in from Hell was very hard to endure.
If I went the Chord route, I'd certainly heed their advice esp re warranty. I believe the issue is that so many specialist LPSs are not strict on voltages leading to (potential) malfunction. Whether this is BS or true, the one or two reviews I've read state there are only marginal gains to be had going LPS.
Can you Chord fans try and describe what is appealing to you and where there is a step up over competing dacs?
In the end, I'm gonna have a shortlist of not more than 3-5 dacs, Chord may end up more the outlier compared to Kitsune Edition Holo Springs, Lab12 Dac1 SE and Aqua La Voce S3, these latter three being Ladder R2R tech.
