Yes, indeed! The same reviewer has also reviewed the Nagra and CH pre and power amps.
I don’t think anyone, except DartZeel, can match Nagra’s HD Preamp. And if you get the pre, it makes sense to get the amp (at least at some point), as there are important synergies for any manufacturer between pre and power amp.
Generally, the Nagra is viewed as more “musical” with no loss is detail, soundstage, noise floor, speed, etc, that the CH has. Of course you can’t really go wrong with either, and some will prefer the CH. For example, if your speakers are tonally warmer than neutral, maybe you would prefer the CH to balance the sound.
