notchasingrainbows Posted May 24, 2019 Share Posted May 24, 2019 Hi, finally received my Gryphon Diablo 300 after almost a month delay from the promised date by my local dealer. Question is regarding setting my chord qutest’s output volt. Under the gryphon’s spec sheet of the diablo 300 it says the input sensitivity is 0,617V abit lower from qutest’s lowest output volt which is 1 V. So what is your recommendation/solution for this? Should I just leave the qutest at 1V? Will there is any cutoff/distortion? Anyone w this experience? Your feedback would be greatly appreciated. Thanks in advance.

georgehifi Posted May 24, 2019 Share Posted May 24, 2019 (edited) If you have enough volume for the loudest your going to listen too, then there is absolutely no problem. And don't listen to ANYONE talking about "extra headroom", even if the Diablo's volume is almost full up. If anything it's an advantage this way because your noise floor will be the lowest, as your not raising the Qutest signal/noise then shunting back to ground again by turning the Diablo's volume down more, your using almost all of the Qutest's output, instead of throwing it away to ground.

It is amazing how it transforms my whole system into a new diff level. And no didnt get the optional dac nor phono. Chose to go with an external dac, chord qutest for future upgradability and it sounds amazing. Link to comment Share on other sites More sharing options...
Simon de Pass Posted May 25, 2019 Share Posted May 25, 2019 Thanks for getting back to me. I have heard one and loved it. I heard it with the DAC module and loved it. Through some TAD speakers. I have a PS Audio DAC. If you don't mind what did you pay for as I believe they are $23500? Link to comment Share on other sites More sharing options...

Simon de Pass Posted May 26, 2019 Share Posted May 26, 2019 Sexy Times!!! Fun time ahead for you! One of the best looking amps around! Link to comment Share on other sites More sharing options...
notchasingrainbows Posted May 26, 2019 Author Share Posted May 26, 2019 Much appreciated @sdepass! Still need to break in a couple of things, the diablo300, receptacle and speaker cables. It sounds a bit weird when the amp was first installed. After the 20ish hr mark it sounds better. Get yours soon! The only thing holding the amp back I think are the n803. Should get a new pair sometimes next year. 1 Link to comment Share on other sites More sharing options...

Actually I am waiting for the upcoming Vermouth Audio’s latest floorstanding speakers which is under R&D process now. Had a chance to check it out when I visited their workshop last week in Bali. It’s a limited edition of 10 Using adjustable (front to back) ribbon tweeters and their custom spec’d driver from SB acoustics. Reserved no.10 for myself next year when it is released Edited May 26, 2019 by kerisabe Link to comment Share on other sites More sharing options...

You should check them out, or even listen to their system and cables when you get a chance. Hope to be able to test the prototype of their latest floorstanding speakers paired w the diablo 300 in the next couple of months. Will post updates 2 Link to comment Share on other sites More sharing options...
notchasingrainbows Posted June 16, 2019 Author Share Posted June 16, 2019 (edited) Update: for those who are planning to use chord qutest dac with gryphon diablo 300, the output voltage setting of the qutest should be set at 3 V, ive done some listening tests between the different output voltages in my system and it sounds best with qutest/diablo300/nautilus 803 combination.
