The 301 does sound tremendously good. It was a bit of a leap of faith, with the benefit of the 11kg brass platter and the LDA power supply ensuring speed stability. Plus it looks nice compared to the black thing I had before. The veneer is the same as used through the ground floor of our house and on the rack shelving.
I went through some fairly budget phono stages (Vertere, EAR Phonobox, Whest Two.2 Discrete) and for some years had an RCM Sensor2 Mk2. I then went for the Mofi unit. It's a brilliant concept, isolating the power supply, phono circuits, and cabling (AC, DC and signalling) with an extremely short signal path. It can connect up to three inputs. One is fully balanced with a transimpedance (current) circuit. All the settings can be controlled from the remote, with an automatic temporary mute.
I had a Zen Mk3 and only upgraded to Pulsar 2 years ago. The NG has a new processor, but is three times the price and still no fibre input. The Stream 3 seems a sideways move.
I have a VLAN in use through a Ubiquiti managed switch and controller. Data comes down fibre. File storage is networked and I have the option of networked upsampling using HQ Player. This might benefit 16/44 or 16/48 files (my CD rips) because the DAC is NOS without anti-alias filtering, but I can't say I've had an issue with any of those files. Most of them can now be streamed at 24/96 or 24/192 these days.
