    "ASH-400 Project" Sylph Audio FB-100 Stereo Module with advanced PFFB

    Hi amigos, I'm coming back to the forefront with a new project. This time I focused on the Sylph Audio FB100 module, based on a TPA3251 and an advanced implementation of the PFFB. Voltage Gain is factory set @ 14dB (5V/V) on this module. So I intended to couple it to my DAC SMSL D6s which has...

    Fosi vs NCore/Purifi: When would there be an audible difference?

    I'm weighing options for which new amplifier(s) to purchase. The budget option is Fosi v3 or ZA3. The more expensive option would be an Ncore/NcoreX/Purifi amp (from Buckeye). Obviously the latter would have more power and is technically superior. It seems that a v3 of a couple of ZA3 should...

    Recent Purifi EVAL1 build

    Having just sold my Buckeye Purifi amp, realized I had all parts available to build an EVAL1 except the case. Had been searching for a case with serious heat sinks but Ghent’s case is nice heavy aluminum and the back is cutout for the EVAL1 with nice silkscreening. I opted for the version with...

    First Impressions of the Magnepan LRS vs. the LRS+

    After months of waiting, I finally received my new LRS+ this week. I had a chance to do some very preliminary listening and testing. These are my subjective opinions and should be taken as such.

    Purifi updated their website, the spec sheet is now downloadable, and the status of this driver is now 'new' instead of 'preview'. Maybe we can see this being tested in the future? @hardisj Imagine a floorstand/big monitor with 2x this and a well-designed tweeter :)
