Just wanted to share my Piano M1 experience so far:
I contacted Seth a while back when I was setting up the RWA listening room. I mainly use my Macbook as my source (feeding USB into the Isabellina dac), or play vinyl - but I knew I needed to have a CD Transport to add to the listening room for customers who bring their CDs.
So I went ahead and ordered a Virtue Piano M1 from Seth in Black, with a Walnut top (which looks very classy and closely matches my Walnut equipment rack). I love the size of this CDP, and upon opening the box, I was very impressed by how solid and well-built the Piano M1 is. It has nice mass from the solid aluminum enclosure and a hefty toroidal transformer used for the linear power supply (not a SMPS that you typically find in a CDP at this price point).
Based on looks and build quality alone, the Piano M1 is a steal - but it also proved to be an excellent transport for the Isabellina. I am getting great results using both the coax and optical output (I haven't done enough A/B'ing to determine which I prefer using).
While I do prefer the analog outputs of the Isabellina and bought the Piano to use as a CD transport, I did try the Piano's analog outputs and they are MUCH better sounding than many CD players that cost quite a bit more than the M1 -- Good tonal density, doesn't suffer from a sterile digital sound, no harshness in the top-end, and nice PRaT.
I'm really impressed with the Piano M1 - it is a silly-good value! It'll be staying here for a long time. Nice work, Seth!
