Audiophiles – a rant and a wish

Audiophiles take a lot of abuse. Why the hate? Perhaps it’s the snobbery often associated with us that puts people off. I don’t really know for sure. What I do know .. we love music and persue the fidelity of it to the extreme (at least by some standards). Like most hobbyists we enjoy focusing on the minutiae. Such is the world of the hobbyist whether you’re into collecting coins, building model airplanes, or whatever floats your ship-in-a-bottle. Nature of the beast.

Sure, there are some audio snobs among us who spend $10,000 on a cable and tell us lowly enthusiasts our systems aren’t “good enough” to hear into the recording. Yeah, okay. Fortunately, said snobs are few and far between. I find most audiophiles are first and foremost music lovers and are a rather helpful lot .. we love to chat about all this stuff.

On a number of audio forums as of late audiophiles are spewing vitriol at one another with increasing frequency. This is disheartening to me. Where’s the friendly banter? Isn’t it enough that non-hobbyists take pot-shots at us and think we’re crazy? Healthy debate is one thing but the nastiness has gotten out of hand.

I’m not an engineer. I have no training in audio production. Nor am I an authority on anything audio. I’m just a music lover; thus, a subjectivist. As long as I’m not declaring absolutes (i.e., the best amp/DAC/cable, etc.) what’s the harm in sharing my highly subjective opinion? No, I won’t be setting up double-blind tests with golden-eared 18 year old virgins but I will be listening with attentive ears. My ears. My system. My room.

The beauty of audio forums lies in the sharing of experiences and information with other enthusiasts from around the world. This sharing helps to guide us through the myriad of choices available, especially in this noisy internet age we live in. Such diversity only adds to the collective knowledge of the community, of which, I’m happy to be a part of.

So, my (audiophile) wish going into 2018 is for less nastiness and more camaraderie.

Cheers!

 

EarStudio by Radsone

In early July 2017 I stumbled across an interesting product on Kickstarter and decided to back it. The Radsone EarStudio Bluetooth Receiver is quite the little gadget and proved very timely for me. Anticipating my next mobile phone would likely come sans headphone jack I began looking for alternatives to Bluetooth headphones and the dreaded “dongle”. Frankly, I have enough headphones already and didn’t want to invest in another pair. The 2 headphones I most often use are the Audio Technica ATH-R70x and the Bowers & Wilkins P5.

The EarStudio packs quite a bit of techno-wizardry into a tiny and very light-weight box to which you connect your corded headphones. Rather than re-hash said wizardry the Radsone’s Kickstarter page, along with these 2 reviews, sum up the device quite nicely:

Major HiFi – October 2017

TechHive – July 2017

Jack sh*t

Soon after backing the project I settled on the Google Pixel 2 which, of course, has no headphone jack but sports aptX HD capability and, as it turns out, aptX HD is right in the EarStudio’s wheelhouse (so to speak). After a longer wait than anticipated Radsone shipped the device to us backers and I must say, it was worth the wait .. the sound quality is the best I’ve heard from Bluetooth.

The EarStudio doesn’t appear to be available on the open market quite yet but no doubt you’ll be hearing more about this great little device in the near future.

 

Vacuum tubes

While I’ve had some experience with vacuum tubes in the past, it’s been extremely limited to say the least. I have a tubed CD player (Ah! Njoe Tjoeb 4000) which utilizes two 6922 tubes in the output stage and a tube/solid state hybrid integrated amp (Response Audio RAM 301) which utilizes two 12AU7 tubes for the preamp stage. As for an all tubed design, I was a complete novice when I purchased the APPJ PA0901A  integrated SET amp a year ago. This minimalist integrated has only one pair of RCA inputs and a passive volume control to attenuate the output of its tube circuit (6N4/12AX7 feeding a single 6P14/EL84 per channel).

Rolling along

It wasn’t until recently I decided it was time to try some different tubes. Why now? First and foremost, I liked the sound with the stock Chinese tubes and wanted to be completely familiar with the sound quality before swapping them out. In fact, I liked the sound enough that I didn’t bother changing the tubes before the summer heat arrived .. I like to use a cooler running amp during summer.

Over the years I’ve read countless reports of huge changes rolling tubes and, while I know there must be some truth to it, I’ve often wondered if there isn’t just a bit of hyperbole involved. Audiophiles are often prone to such exaggeration when changing anything in their systems citing massive gains in sound quality, veils being lifted, larger goosebumps, etc., etc. Color me skeptical.

So, Christmas present to self:

  • Genalex Gold Lion 12AX7
  • Mullard EL84 (matched pair)

These 3 tubes cost me just under half of what the amp sold for a year ago and was about as much as I wanted to spend. The result .. massive gain in sound quality, 7 veils were lifted, 6mm goosebumps emerged, and ..

Seriously, the APPJ PA0901A sounds like a different amp. Tone, timber, clarity, extension, soundstage, vocals .. everything changed for the better. Of course I had hoped for a result such as this but honestly, I’m somewhat flabbergasted. This isn’t a subtle change, I actually uttered “wow” during my first listening with the new tubes. To say I’m pleased is an understatement.

While APPJ has since discontinued the PA0901A in favor of it’s newer 1501A model, Tube Depot sells it’s own (re-branded?) version found here: TubeCube | 7 Stereo Vacuum Tube Amplifier. Highly recommended. And roll some tubes!
