| DAC as an attenuator? Zd542. The idea would be to use the DAC to attenuate CD signal into the preamp input so as not to relatively overdrive it, quite common with low sensitivity input line inputs. | |

| How quiet is your Rogue Sphinx? Reynolds853.The transformer hum is audible close up, certainly not several feet away as was yours. The balance hum is more the issue, to be honest if I tried for an exchange with the dealer they probably would oblige especially as they also felt i... | |
| How quiet is your Rogue Sphinx? I'll agree with Donjr, the customer service response is excellent. Mark O'Brien did email me this morning. He suggests that the grounding for tubes and class D to be tricky and that in different environments there may be noise at the balance. He r... | |
| How quiet is your Rogue Sphinx? Reynolds853.the transformer hum you described in the perseus, did that give any noise through the speakers also? Or was it only the hum from the unit itself? I do wonder if my 'variable hum' is related to that which I hear from the unit. | |
| How quiet is your Rogue Sphinx? further to my last post, I have a rega brio in the TV room and the noise consists only of typical 'hiss', noticeable through the tweeter, little deeper in the mid unit and barely perceptible in the bass unit. If I turn up the volume knob to maximu... | |
| How quiet is your Rogue Sphinx? I think what is perplexing about the hum is just how asymmetric it is: turn the volume up and it rises (slightly) on the right, reduces on the left, if you then turn the balance to the left the hum becomes much louder on the right but unchanged at... | |
| How quiet is your Rogue Sphinx? Actually, as it is a very quiet morning I did test the amp, the hum does change a bit as you raise the volume (went to 12 oclock to simulate loud listening), however it is asymetric...it rises in the right channel and reduces in the left! To be ho... | |
| How quiet is your Rogue Sphinx? Devilboy: so did the guy you sold the unit to actually get a repair?I will give some feedback to my audio dealer (with the same noise in their unit) as to Rogue's response. In this situation some people could insist on a return but to be honest th... | |
| How quiet is your Rogue Sphinx? I'm glad I opened this thread at the very least it will make people aware of sphinx's noise and they can check it out for themselves specifically, it's the type of thing I wouldn't have thought of noting on a demo. | |
| How quiet is your Rogue Sphinx? I did ask Rogue if in their opinion the noise was an issue, Nick feels that the amp is working as it should saying that some transformer noise is possible and that some noise from the balance is normal. I still have a three year warranty and unle... | |
| How quiet is your Rogue Sphinx? lowrider57/Reynolds853.interesting that your two issues cover both of my units observations and both were repaired. (The testing was thorough, cables/speakers were switched, even different power cords used.I'll see how Rogue responds next.Thanks. | |
| How quiet is your Rogue Sphinx? I've emailed Rogue again and as both units demonstrated the various noise I have asked if they think this warrants a return, I guess the ball is in their court so to speak, there is plainly an audible hum and the odd unequal hum from the speakers,... | |
| How quiet is your Rogue Sphinx? So an update on the humming sphinx.I took it to the audio store and compared it to their shop floor model, both units demonstrated the same unit hum and noise from the speakers. The conclusion by the store associate was that it was a bit noisier t... |
