My current setup uses all SS gear but I'm keen to explore what tubes can do for my listening experience!  I've got a balanced source (Audio-GD Ref 7.1) and all my headphones are equipped with 4 pin balanced plugs so I'm keen to go for a fully balanced headphone amp.  Having done...

  I am about to invest in a balanced set-up and would like to get my various aftermarket headphone cables re-terminated with 4-pin balanced plugs.  I'm no expert with a soldering iron though so I was wondering if anyone could recommend somewhere in the UK (ideally London but doesn't really...

I love my HD650s for listening to bright recordings when my more aggressive headphones sound too harsh/ssssibilant and become fatiguing very quickly.  However, the 650s were actually just a little too smooth for my tastes (no doubt the "infamous veil"!) and so I started to consider a couple of...

I'd like to upgrade the op amp module in my EF-5 to an OPA627 (vs the stock OPA275).   Does anyone know where I can buy one? (I live in the UK)   I'm pretty new to op amp rolling and searching on google wasn't much help!

I'm keen to upgrade the stock cable for something that would smooth out the top end of my HE-5LEs (currently amped single ended out of an EF-5).  Any suggestions please?   I'm based in the UK so would prefer to buy something here if possible (much easier to sort out any problems if they...

I recently bought a pair of HiFiman HE-5LE headphones, but even after 300 hours of burn-in/use, I'm still experiencing issues with quite spiky treble and ssssssibilance.  A small tweak downwards of the EQ settings at 4k and 8k (in MediaMonkey) seems to sort things out but having read in various...

I'm considering taking the plunge on a set of custom IEMs. I have (almost) settled on ACS as I like the all silicone earpieces (and I live in the UK).  However, not sure whether to go for the T2 (dual driver) or T1 (triple driver - updated in 2010).   Can anyone who has listened to both...

I recently bought the Audio GD DAC 19 DSP and C2 amp combo (connected using ACSS).  I love the neutral, detailed sound but am having problems with sibilance on my existing headphones - a pair of Hifiman HE5-LE, which I usually use with my EF-5 amplifier and a HRT MS2+ DAC running out of my PC...

I'm getting fed up with hearing interference from fellow commuters' mobile phone signals/blackberries...etc on my B&W P5s!  Does anyone have any suggestions as to where I could buy a better shielded, high quality replacement cable?  I don't use the remote control/microphone so a cable without...
