| How quiet is your Rogue Sphinx? To go a bit further. I did feel a bit burned with the noise issue on the amp, Rogue suggested it was a product of implementing valves and class D, unfortunately my dealer had a no return policy after home demonstrations, I did not notice it until ... | |
| How quiet is your Rogue Sphinx? I have yet to purchase a replacement amplifier, for the time being I am using some pro equipment to run my speakers. Jspively, apparently the original version sphinx does have this noise issue, some may not object but in comparison to say a NAD 36... | |
| How quiet is your Rogue Sphinx? A late follow through to this thread. I did unfortunately abandon the sphinx primarily because of the noise issue, I feel it is an otherwise competent unit but that level of noise was simply unacceptable, a sub $1000 NAD unit by comparison was pra... | |
| DAC as an attenuator? thanks for the responses all. Definitely something to consider to reduce gain at the preamp input. Despite my amps quoted 1V input sensitivity I still find some CD's get 'shouty' at around the 8:30 position on the amp and at that point anything lo... | |
| DAC as an attenuator? EDIT: that would be HIGH sensitivity line inputs. | |
| 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... |
