Today i got reacquainted with my old speakers after months apart.   I didn't have any gear on hand though, so with a little work i powered them straight from the headphone jack of my iphone4. I got a fair amount of volume, so for curiosity's sake I'm pretty seriously keen to know how much...

Alright, like I said before, John from Coem Audio has offered to support/sponsor the meet.  This is their website: http://coemaudio.com.au/     John said he's happy to lend any of the products for the day if he has audition stock. So have a look and let me know if you'd like me to...

I haven't been too active lately but MomijiTMO PM'd me to ask if I want to come, which I think I will. I don't hav ea heap to contribute though, My Firstwatt F2 has just recently been broken down into pieces to do some work on it. Hopefully I'll have it back together before the meet because it...

Okay and lets expand this some more.   The large case will enclose the transformer, PSU board and the audio board.   I was already planning to case the transformer in its own little steel enclosure inside the larger case. How would you best wire it for the best shielding? Earth both the...

Oh thanks. My initial concern was that earthing the case would effectively short the case to the psu earth. sounds like your suggestion solves that worry

I'm finally casing up my DIY Firstwatt F2. I'll be doing it mostly in steel. The PSU is already connected to the earth. Should i wire the case up to the earth too?   Thanks   Hugz

My current rig uses: Storm Dac d02 (NOS. Very rich and warm sounding) either stepped attenuator, or a tube preamp that i dont like much Firstwatt F2 power amp (Solid state, mosfet, single ended transconductance amplifier) speakers or headphones   So i want to replace my "preamp"...

I've been connecting my headphones directly to the speaker jack of my speaker amp for about a year now. sounds great, no worries about blowing anything up i used a resistor across it for a little while to drop the gain and the decrease in sound quality is certainly no where near what people...

I run a Rancilio Silvia and Rocky (doserless) (not my photo. i dont own a camera, and even if i did i couldn't take a nicer photo than this one! photo rehosted but taken from here) In time I'll PID it to make it a little easier to use, but frankly i can make a better coffee with it than...

skip the dared mp-5. cayin ha-1 is a pretty darn good amp that does 2.2w in ultralinear and 1.4w in triode photos here http://www.head-fi.org/forums/showthread.php?t=138581 i'd be a little bit concerned about whether it can power your speakers though. i remember it powered mine decently...

hey all, i've got myself a little problem i'm in the market for a balanced dac and a balanced power amp, but i've just realised that my preamp is.. not balanced can anyone recommend some balanced preamps? preferably not too cost. preferably tube (am i contradicting myself)...

i must admit, xlrs confuse the heck outa me. it's true. from what i can tell, a balancd audio xlr should use 3 pins. if this is the case, why do i always see 5 pin xlrs around the place? secondly, what's the general standard of male vs female? male goes on the cable end and female on the...

for clarity, you're putting the ramen in cold water and then microwaving for 4 mins, eh? i use a dif method and usually start with boiling water but thats a pain in the ass, so i'd be happy to replace it with cold water

I work at a doctor's which doesn't charge for a normal appointment, but DOES charge for things such as vaccines. thus people are often caught off guard. it's interesting to see how many people not only do carry any cash in their pocket, but have no money in their bank accounts. often they'll...
