Holo Green / Cyan - DAC+Headamp Intro With the new Holo combined DAC/headamp now formally announced and pre-orders being taken, first deliveries are expected in a few weeks. So time to start a separate impressions thread just for this product. This is essentially a new version of the Holo Spring designed for headphone users - something I have been waiting for. I don't own a Holo or have any association with them but have been aware of them through very positive user reviews. The Spring contains 2 ladder DACS - one for PCM input and one for DSD. With the Green/Cyan, the first model being released contains 1 ladder DAC and 1 headphone amp instead. Essentials This first model contains only the PCM R2R ladder DAC - this will play your normal redbook and much higher resolution files and it will convert DSD files (up to DSD 256) to PCM files for playback - as many (most?) DACS claiming to be DSD capable do. The Spring and a minority of other DACs do native DSD (better for the purists and I do have one of those other non-holo ones) and there is a later version of the Green/Cyan coming out for this. Inputs are : -USB (isolated from ground) -Coaxial (RCA) -Coaxial (BNC) -AES -Optical -I2S - HDMI interface (DSD256) -USB and IS2 support DSD DOP mode DSD256 and all other digital inputs support DSD DOP mode to DSD64 Outputs are: - Fully balanced/bridged XLR and RCA output - Balanced headphone output using 4 pin xlr Other points of note: • The clock is a still a femto one but not quite the same as in the Spring, whilst the USB input has apparently been upgraded compared to the USB input on the Spring. • Offers oversampling and non oversampling modes • The case is smaller than the Spring being 281 * 260 * 55mm or 11* 10 * 2 • The new fully balanced headphone circuit • Ability to select either low impedance or high impedance for the headphones and to change this easlily • The remote control functions include volume as well as switching between low & high gain to satisfy users of IEM's through to tougher to drive full size audiophile headphones. • Jeff the lead designer has commented that unlike other integrated units where the headamp has been poorly regarded he wanted to build a decent headamp inside. • Price - ~20% cheaper than the Spring • All info above from vendor's preliminary info Impressions I have pre-ordered one and might add some impressions in a few weeks - but I look forward to impressions from more respected 'trusted ears' Now I am certain some readers could criticise my summary as not being accurate enough - but please don't rush in to do so - we all can hopefully contribute as more information and knowledge from use comes to hand. Hopefully this will add a new quality product to choose from along with those from the many other vendors releasing quality hear. Please add your impressions from actual use of the Spring or the Green/Cyan. Photos below - will post better ones when received.
