<p>Audiophiles exist in the world. You might have had a conversation with one of them. You can easily recognize an audiophile when they tell you how good music sounds on vinyl. I am not saying that I am an audiophile per se, but I see how someone gets there. This is my story.</p>

<p>With the stay-at-home order, I found myself looking for things to do around the house. I am doing my own yard work, starting a garden, and arranging things. I did notice stacks of CDs from my 90&#8217;s college days. Filter. Smashing Pumpkins. Nine Inch Nails. Tool. Christina Aguilera. For the past decade, I have been listening to music via MP3s or streaming services. Music has become background music in my life. Except for the Trolls soundtrack. I have heard the Trolls soundtrack on Amazon Echo for both movies probably 100 times. My son loves Daft Punk. We play the song <em>One More Time</em>, one more time frequently.</p>



<p>I wanted to listen to the CDs and I discovered that I have 3 devices in the house that play CDs: a CD drive in my PC, a disconnected Blu-ray player, and a Trolls themed CD player/radio. I got the &#8220;hug, sing, dance&#8221; player at the thrift store for my son which included the Frozen soundtrack disc in the player for $2.99.</p>

<p>The first CD that I listened to was <a href="https://amzn.to/2LgT1AQ">Filter &#8211; Title of Record</a> from 1999. I couldn&#8217;t believe how good it sounded coming out of my computer speakers. My ears have been listening to compressed, streaming audio for over 10 years. I started digging around the closet for a nice pair of headphones and tried my earbuds and a pair of AKG K240 Studio Monitors that I got as a gift. The earbuds were OK. The AKG headphones were worse. I expected a lot out of them, but they didn&#8217;t sound great. I turned to Google and search around for an hour and discovered that the AKG headphones have a high impedance of around 55 ohms and my computer doesn&#8217;t really support that. This finding led me to a number of high-fidelity audio forums. I learned about headphone amplifiers and digital-to-analog converters (DAC).</p>



<p>I decided to experiment and ease my boredom a bit. I bought a the <a href="https://amzn.to/2Ae1GSg" target="_blank" rel="noreferrer noopener">SUCA Audio</a> tube headphone amplifier that was recommended to me on one of the forums. I waited a couple of weeks to get it and built up the anticipation of plugging in my AKG headphones.</p>

<p>Wow. Wowzer. I could believe how good the music sounded. I enjoyed the warmth and overall tone. The SUCA Audio amp is arguably a low entry point into headphone amps. My research over a few days showed me how deep this rabbit hole goes. There is an endless supply of gadgets to elevate your audio experience.</p>



<p><strong>Going next level.</strong> I kept reading mentions of other vacuum tubes to try. I learned about the RCA 6AK5 tubes to get even better sound. I found a pair of &#8220;new&#8221; tubes on eBay and tried those. eBay tip. &#8220;NOS&#8221; means New Old Stock. They don&#8217;t make vacuum tubes anymore so you have to find new, old tubes. You also want to find a matched pair. And, yes, I can hear a difference. Or, I am not admitting that I can&#8217;t hear a difference &#8211; that&#8217;s part of the audiophile&#8217;s code. </p>

<p>This is my first toe into the deep waters of HI-FI audio and the water feels great. I have been enjoying some old tunes and hearing things that I never heard before. Maybe one day, I will be the guy at the party telling you about my audio gear.</p>
