Re: X-cans problem/question
|Originally posted by Jacobh
I noticed when plugging in headphones (or unplugging them) to my X-cans V2 there is a sound like a spring vibrating in the left channel. Tapping the volume pot, the headphone cord, or the top of the unit produces the same effect. The top of the unit has to be tapped harder to have an effect. The volume of the vibration seems to based on how hard the unit is tapped and is not influenced by the position of the volume control. When the unit is not plugged in, there is no sound from tapping the unit. I noticed this behavior with both my Grados and Sennheisers. Have other people heard of anything like this or is something damaged?
I haven't noticed any problems during normal listening.
In the another thread headed "Smooth Cables", started by blr, I have commented that the X-components are quite microphonic, ...
" Happy to help, Blr.
FWIW and simply FYI, I felt that I should mention that I have auditioned the various X-components from Musical Fidelity and I have consistently discovered that the they generally are quite "microphonic" even though they are quite solidly built gear. I have tried the X-Act, X-24kDac, X-Pre, X-Can, and X-10D and they all seemed to benefit from some additional isolation, from the hard surfaces they were resting on. Glass shelves certainly did them little favours and placing them directly on top of another component is also not recommended, IMO. "
So, Jacob, ... the X-Act and X24k Dac are relatively less prone to microphonics, whilst the X-Can and X-Pre are relatively more sensitive to resonance/vibrations and based on my own listening experiences, they do tend to exhibit more microphonics. Saying that, these units does response positively with some level of isolations, using say, vibrapods, sobothane and other similar resilient type feets.
Well, check out the "Smooth Cable" thread, and you will read about blr's experiments, in his attempt to isolate his X-Can, with the hope of taming some subjective HF peaks that are annoying him.
Finally, the vol switch in the X-Can is nothing great ... cheap stuff really, mass produced, cost efficient and it works ... but do realise that the X-Can is built to a limited budget, to a price point, and because it so happen to sound very good for the money, many of us tend to expect too much from that little marvel. I would not be surprised if a major portion of the budget has gone into the casing itself and inevitably, some "corners-cutting" cannot be avoided, but fortunately, the MF people still managed to squeeze out relatively good sonic performance and make it look funky as well as incorporating a tube output stage !!.
Well, that's my 2 cents worth.
