I have a 10 yo pair of Senn HD600s.  I like them.  They sound fine to me.  But I'm SURE they can be improved!!  I just know it!   So here's the options I have investigated, and I'd like your opinions thereon.   1.  Buy a replacement cable.  There are 4 I've found:  One from Cardas, one...

Hello everyone - I've not been around for a while (and obviously you didn't miss me!) for various reasons, but now I'm back and need your opinions. ' I currently have a Singlepower PPX3 (6cg7 version), which works fine (so far anyway), but with all the reports of problems with Singlepower...

What is a reasonable price to pay for these tubes? I have one quote of $30 each from a very reputable dealer. I've seen cheaper prices on Ebay and A'gon, but have no way to judge the reputation of the sellers. Your input appreciated.

I have some money to spend, either on music (cds) or on hardware (strongly considering Cardas headphone cable for my HD600s). How do you think I should spend it - music or hardware. I'm leaning towards music. Your thoughts appreciated!

My PPX3 arrived with a throw-away 18gage power cord. I replaced it last week with a Volex 17604, which is a 14ga SJT cord which costs < $6.00 (plus shipping) from Newark Electronics. The improvement is small but very noticable - improved bass and mids, and better musicial definition. A very...

It arrived on Friday, July 2, and I am a happy man! I have a few hours on it now, and it's sounding better and better every time I use it. I'm expecting great things from it. Last night, I played the Ray Brown Trio "Summer Wind" disc, on Concord, and was hearing things I didnt know were on...

This unit has just come to my attention, and looks like it might be the answer to all my prayers. How is it as an amp, and as a dac? Thanks for your input

I was fully prepared to buy one of these units from Audioadvisor for $350; I will not, however, buy one for $599. Especially since I am having 2nd thoughts about my previously expressed intention to buy a solidstate amp: the MG HEAD OTL has come up on the radar as a fine little amp for my...

I have been using a Mu Fi V2 amp for several years now. It's a nice amp. I changed the power supply capacitors and it sounded even better. I even drilled out the case to provide some ventilation, which also seemed to help some. And I bought a much beefier power supply, which made it sound...

My mildly modified X Cans V2 seems to be running warmer than usual, so I am considering drilling some ventillation holes top and bottom. Has anyone done this? The mods I have done are: (1) using 4500ma power supply in lieu of 500 ma supplied power supply; (2) changed out all power supply...

Recently, I considered purchasing an X-psu power supply for my X-Cans v2, but was reluctant about the price. After a little reasearch here and at AudioAsylum, I purchased a 12vac/4500ma power adapter from hosfelt.com - cost less than $20 including shipping. What a difference! The bass firmed...
