Lampizator Amber - I am going to preface this by saying I am testing this unit with stock tubes. I have no interest in rolling and optimizing as I have no plan to keep this unit for myself. Lots of threads in other forums on tube optimization for Lampi so no need for me to dig into this.
The Amber 4 is as nice DAC that is engaging and easy to listen too. The version I have is an XLR model with a built in volume control. It also has an analog input and can serve as a preamp. The closest competitor to this unit is the Rockna Wavelight.
What is immediately obvious is that with the stock tubes, this is easy listening but far from the be all, end all in terms of detail. In a Sentimental Mood is lovely. There is sparkle on the top end and very musical. It feels like there is a touch of smearing in the drum rolls
In Be Still My Beating Heart, soundstage is huge. Great width. Nice depth but lacks the stability of more premium DACs. Nosie floor through XLRs is quite low, espcially for a tube unit.
Liberty had zero sibilance. Effects were muted but coming from a distance. Staging is good but again, not the most focused image.
in the opening of Duende, there is noticeable smearing in the bass solo. This sounds smoother than more premium DACs but is not necessarily how it should sound. Dynamics are great and it is fun and easy to listen too.
On the Berg piece, strings feel somewhat massed and the intimacy is lost. Exactly what I would expect at this point in the demo.
Flaty, this is a very enjoyable and easy to listen too DAC. It reminds me of the PS Audio DSD in some ways. With stock tubes, it has excellent staging but lacks the detail and stability of the best units in the price class. Not sure how better tubes will impact this but have to assume it will improve it.
