The Second Coming
below is a list of upgrades to our current model:
Tube Life-Saver: MK2 automatically shuts-off after 30 minutes of silence.
Upgraded remote: MK2 comes included with the new MK2 remote
Volume: volume control has 4 times the resolution of the previous generation, resulting in finer increments. The 30dB increase in attenuation means a lower minimum volume.
Amplifier Module: MK1 used ICEpower 125ASX2. MK2 uses ICEpower 200AS2. Output RMS power increased from 120W to 215W@4Ω / 60W to 120W@8Ω.
Tube Preamp: redesigned to operate at double the voltage, the new preamp has a similar sound signature to MK1 while minimizing gain variability from tubes.
Headphone amp: rebuilt around the TI OPA1622 chip, the MK2 headphone amp has better dynamics and higher gain (142mW@32Ω).
Coax input: new this year, a coax input with sample rate of 192k@32bit.
Bluetooth input: featuring AptX HD encoding, the module has better range and is 5.1 BT compliant.
Phonostage: upgraded capacitors. Comes with high gain jumpers for low-output MM cartridges (2-3mV).
Switchable Pre/Line Output: the pre out can be switched to a max output line out. Both signal paths pass through the tube preamp.
240V Volt Models: While 240V stock was problematic in the past, we’ve now solved this issue using new dongles that can configure any amp as 120V or 240V. Configure your amp to your home country voltage, but should you move, dongles are available here.
Chassis design: MK1 was made using an off-the-shelf T6061 alloy aluminum profile. MK2 is machined using our proprietary profile, made of T6063 aluminum. The T6063 alloy has better heat dissipation, thermal conductivity, corrosion resistance and surface finish. The profile thickness is consistent all-around. But most importantly, the profile production is subject to our own stricter manufacturing tolerances.
The inner chassis and backpanel are made of stainless steel (same as MK1.5), with the speaker posts spread out horizontally to better accommodate larger speaker cables and spade connectors.
