Upsampling DACs


What are some of the better high end upsampling DACs out there today? And are any of these upgradable. Thanks.

Look on my thread about the Allnic D5000 DHT.

It best my EMM dac2x by a wide margin and much cheaper. It is more versatile than the Empirical Audio Overdrive SE but produces a different sound. Although Empirical does not upsample, it plays redbook files better than the same tracks in DSD format on the EMM.

I have not a to b the Empirical to Allnic formally. However, Allnic has not left my system. Often times I get hairs standing up my back on certain tracks and I really like that.

I have a review pending for the Allnic D5000. What part of the country are you located?

I would be interested in hearing a to b with Lapmi series dacs as this would be a great comparison.
The Vitus RD-100 is an excellent upsampling dac and employs filter-down technology from the previous Signature series spinner (SCD-010). It also includes a good analogue linestage which uses a new version of Vitus's relay-based volume control and 2 'true' analogue inputs (1 rca + 1 xlr), including an array of digital inputs.

The RD-100 benefits from extremely wide bandwidth, future-proof discrete modular architecture and impeccable build quality. The sound is neutral, natural, flowing and sounds somewhat tube-like in terms of its tonal saturation, texture and dimensionality. An easy recommendation, unless you need a good sacd player, in which case i'd recommend the Vitus RCD-101. The dac section is in that player is on par with the RD-100, but omits the analogue linestage.
