Luckily John Siau shared a spreadsheet where one can calculate the damping factor of the ENTIRE system (including speaker cable length and impedance). The Matrix has some of the best connectivity options for streaming.Īnyways, I am looking forward to Kal's reviews on the Purifi amps that I may get if I ditch the Matrix.Īctually, most REAL speakers have impedance values FAR lower than their stated nominal value (and higher also).įor example the Revel Performa 3 F208's drop to 3.4 ohms guess where.? Right at 90Hz. It is not easy to say that getting another DAC would have been better. So I have some pretty amazing 2 channel as a baseline. I also have Audience FrontRow speaker cables with SpeakON terminations that were measured (or commented) on this site to be better than banana to the AHB2. The DSP was done by a profession sound engineer who is considered an expert in this field. I also have Convolution based DSP running on ROON for this system. The speakers at the end of my 2 channel system are a completely refurbished (by me) Thiel CS3.7 with OEM Thiel parts (done Oct 2020). Keep using it only with the A90 and Meze, sell it, or get a warm amp. Of course there are 3 ways to solve this. Taking the Matrix to my dead neutral 2 channel system I could hear the deficiency in this DAC. I now realize the reason that it sounded great was because the Meze Empy is a warmish headphone. I had been using the Matrix with the Topping A90 headphone amp and the Meze Empy headphone. That may have been in another ASR thread where Matrix participated. I saw that and then a few posts that the issue was resolved. ![]()
