I've heard the Lumin AMP and it's an exceptional performer. It runs pretty hot apparently due to a high level of Class A bias. Very clean and transparent sound with a natural tonality and no typical solid state signature. Not inexpensive but it's the kind of component that once you experience can be difficult to move past... you have been warned.
Now you're really tempting me! From my experience with the P1, I'm very impressed with how well Lumin
thinks things through.
From the core design parameters, the technologies and engineering approaches embodied to provide the various functionalities, e.g. utilization of optical interfaces, dual-mono circuit topologies, sophisticated and dual-mono power supplies and transformers (e.g. Plitron transformer for the shielded power supplies and Lundahl transformers for the digital section), cutting-edge methodologies e.g. LEEDH volume control, and subseequently, how well they execute on the design parameters and engineering specifications.
An example that most folks might not consider is the front panel and chassis. This panel is solid and machined from billet, and provides damping from vibration imparted to the chassis. The top/side cover are well-damped as well, and I'll add that with respect to damping against vibration, having the
right amount of damping is important, there's a "sweet spot" so that the component is not impacted by vibration, but is not overly-damped so that it sounds "dead". Same applies to the footer design used. I tried placing my P1 on the HRS Nimbus couplers and spacers and, it sounds better on the Lumin footers.
Thomas of Thomas & Stereo did a nice review of the Lumin AMP...
