It was about 1.5 years ago when I published my comments on the Yuin PK1. For those you that don’t know me (have been away for too long), I am and remain a self-proclaimed IEM guy. Starting with Etys (now some 10 years ago), I've been through Shure E2s, was an early adopter of the Shure E5s; used...

Look here

I am very sorry but I will not be able to set up and host the meet this spring. Myself, Nate, and Haj are all full out with work and home and we'd simply not be able to do the meet justice. I'm now shooting for a meet in late July. Best regards, and again, my apologies, Dave...

One of the dangers of purchasing a balanced amp is the question of how good a particular headphone might sound when driven in balanced mode. With the recent acquisition of the very nice sounding Rudistor RPX-100, I started with balancing the Grado HF-1 (effing awesome sounding when balanced) and...

My black Rudistor RPX-100 has arrived, and it is gorgeous simplicity. From the RPX-100 color choice thread, where matching other gear was a suggested course for silver versus black, it matches the brushed black aluminum of my Opus 21 perfectly. The milled-out areas for the phono plugs and...

Any of you Stax fans know the maximum amp power (if any) the Stax SRD7 Pro can accommodate? I would like to try it with a power amp (B&K EX4200), which I believe is rated for 200wt/ch. Documentation on this device is scarce to type the least, and I would rather not see the adaptor or my...

I am a self-proclaimed IEM guy. Starting with Etys (crap, ~9 years ago), I've been through Shure E2s, Shure E5s for 1.5 years, and two years with the very excellent Sensaphonic 2X-S. For business travel and work, I've been using highly modified KSC-35s (recabled, resistor mod, driver cover...

For anyone that's reterminated or replaced a Grado headphone cable, are there four wires for the entire length of the cable; all the way to the phono plug? RE: I thought I'd read a post where the left and right ground were joined at the Y connector and a common ground was used from the Y to the...

I just opened a fresh pack of KSC-35s to break in and then modify. While listening to my SRF-S84 radio and then another source, I thought they sounded somehow different. When I plugged in my Nano/Hornet, it became clear why they sounded different: the left and right channels are reversed. It...

I had my 4 Gig Nano undergo Red Wine Audio's iMod, where the line-out is taken directly from the DAC chip. This bypasses a bunch of parts, cables, etc., making for a very clean output. It eliminates the need for a line out adaptor, such as a pocketdoc; makes for a smaller overall solution...

This is an interest check for getting together some time this fall. I'll try to get the same conference room in Marlborough for the event, unless someone would prefer a different location. Hopefully I can squeak out a better price to boot. After the interest check and your positive...

I received my new Ear+ HD yesterday and am so far extremely pleased. Dealing with Dr. Peppard was a great experience throughout the process. Being time limited, I had the good doctor assemble the amp for me. The build quality and point-to-point wiring is very nice. I like the fact that I can...

I’m at this moment sitting on a picnic table in the middle of a campground, posting this with my laptop connected via my cell phone and Bluetooth dongle. No chirping crickets or nearby dogs barking for this camper, I’m spinning tunes through my Mini-DAC and PS-1s. No amp, just a bat operated...

About two weeks ago, I posted that I'd pulled the trigger on a pair of RS-1s. In the same thread, I received what I thought to be the regular Head-Fi humor and bantering: Quote: Originally Posted by grawk Congratulations, when are you ordering your PS1s? I must admit that at the...

At the moment, running them from the headphone out of my Apogee Mini-DAC (optical to PCDP source). The Mini creates an incredible synergy with these cans; one of the best minimalist rigs (IMO). I'm not finding them to be at all fatiguing or bright. Still adjusting the band and such but finding...

There have been several positive mentions of driving the HD650s from the Benchmark DAC1's balanced outputs. Has anyone tried driving the Apogee Mini-DAC from the balanced outputs? I may soon have a chance to audition one or both. Unless I modify the 650's original cable beforehand, I won't...

Today, I started modifications to my Sony D-25 as discussed in a few threads from the middle of last year. Given the age and length of the old threads, it seemed more appropriate to create a new thread. The thread that speaks to the op-amp, PS cap, and DAC modification can found here Changing...

I have a section of Kimber PBJ and want to build a mini-to-RCA. If you have one of these and don't mind confirming its construction…. Three strands exiting the mini, and then two strands entering each of the RCAs. For this to happen, I suspect an additional ground lead is spliced in at the...

I have a Headsave Tempo that I'm currently running with a 16-cell pack. Given the fact this amp will suck the batteries down past (way past) 1.05 volts per cell before shutting off, I surmise that the minimum voltage is actually quite low. Is there much of a difference between running this...

I want to build an external battery pack for a Sony D-25 and a Sony D-11. Anyone have experience or knowledge of the voltage range at which these units can "safely" operate? What I want to keep from doing is building a pack that will fry something. Both have DC 9V plugs (both with reversed...

**EDIT** Nevermind, item found 8~) Mirroring a request in the DIY forum (not certain which is the correct spot): Was anyone successful in obtaining a Sony D25 schematic; one that I can get access to? Thanks, Dave

I've been searching for a pcdp to go with Shure E5s and a Headsave Tempo. Having purchased these two items leaves little in the way of funds so the pcdp is a bang-for-buck venture, at least for the moment. Wanting something with line out and defeatable anti-skip, I picked up a Sony...

What I need: A 5' mini to mini interconnect and a 15' headphone extension cable that terminates with 1/8" on each end. What I have: A 20' Kimber PBJ headphone extension cable that terminates with 1/4 on each end. Rather than sell the extension cable and then buy another with 1/8"...

Greetings from a new member, great forum you folks have here. I've been lurking-n-searching for about two weeks, trying to catch up on technology. After reading this forum and seeing what's out there, I have daily upgradeitis for things I've only contemplated buying. Thanks… I owned a pair of...
