Wiring my Senn 580 directly into my amp. Figured it might offer a tiny improvement since it would eliminate some wires, solder joints, and the connectors themselves from the signal path. There was absolutely no difference.

It must be my DIY power cable which I ordered from a Finnish DIY'er. It cost very little though but there's no audible difference compared to normal cables. Well at least it's better shielded.

Lucky for me I tried my most useless upgrade for free. I tried the Cardas wooden blocks under my components and I honestly could hear no difference.

Di Marzio Hi Def interconnects. No comparison to the MPaths and actually sound very dull.

Balanced Power Technologies BP Jr MK II

My first and last venture into the world of power conditioning.

I obtained a Teac A-L700P pweramp sometime last year to use in my budget 2-channel speaker setup. Then I had to move and have never gotten around to using the amp. It's been sitting on the bottom shelf of my rack for about a year doing absolutely nothing now.

Cardas RCA caps.

But, they do add some style points to the back of my components.

The RCA caps do add much needed bling to any piece of equipment... Too bad they don't come in diamond encrusted!

The worst for me is probably the Naim (I think) distribution block... Sounded the same as a surge protector in my system.

If it’s an Upgrade can it be useless?

Sorry I’m just being obtuse.

My most useless purchase that I had hoped would be an upgrade was a Behringer Ultra-Curve Pro DSP8024 Graphic/Parametric EQ – Analyzer room correction unit. It did what it claimed it would. I gained a flat frequency response, and lost the world. It was truly awful! It was a lesson in how to change a great high end system into a great mid-fi system.

The other all time boner was buying the HD-650’s, but that’s beating a dead horse.

Boutique power cords. I am unable to hear any audible difference what so ever.

My first-gen Total Airhead didn't make as much difference as I'd hoped, though it did provide better volume control and slightly better bass/fullness.

I also bought a Cardas mini-to-mini interconnect to use with said TA. I didn't notice any improvement in the sound, though it wasn't completely useless since my parents' puppy chewed up the stock interconnect. So being able to use the amp again was useful, even if not an "upgrade".

I also built myself an Ety 4P->S adapter. Didn't notice much difference from it, but I also think that's at least partly because I haven't got especially impressive source and amplification. It was cheap to build, at least.

MINT amp.

Gotta say though that it would have been worth it if I had the HF-1s back then. They sound scratchy without amp. With any other headphone (RS-1 included) it's just not worth it.

 

[saturnine]

Zu Birth PC. Couldnt tell a difference between it and a crappy stock power cable...

 

[Steve999]

Bought a used NAD receiver with some knobs falling off and the tuner on the fritz for $100. It's lying around somewhere. I can't even imagine what I wanted it for.

I bought a Super-Mini Moy and ended up selling it.. The sound quality to price to portability/convenience wasn't worth it..
