All our amps and dacs are covered by a 2-year transferrable warranty
We hand assemble each cMoyBB and tweak output power and bass boost for your equipment. Simply specify your headphones during checkout.
cMoyBB is the most fully featured cMoy made.
JDS Labs's success is due to cMoyBB's legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass increases up to 9.4 dB for a perceived 2x increase in bass volume.
Older cMoys use thin wires or protoboard to transfer audio signals. cMoyBB uses a carefully designed PCB with attention to detail that cannot be achieved in protoboard amplifiers, or even in circuit boards designed by experienced hobbyists.
cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters. The result is over 200% higher power handling than the original cMoy! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality.
cMoyBB's power input jack allows you to power the amp from your desk. Optional charging support also provides convenient, integrated 9V NiMH battery charging.
cMoyBB is cased inside of a brand new Altoids ® Peppermint tin, protecting the circuit from some forms of external EMI / RF interference. You may choose between two tin styles: Peppermint or Wintergreen.
Specify your headphones during checkout and we'll optimize gain, bass boost, and output power for best performance with your headphones. A technical summary ships with each custom cMoyBB.
Standard, 1x9V: Best for most users. External DC jack can be used to power the amplifier. Does not charge battery.
Standard, 2x9V: Recommended for high volume listening with 120+ ohm headphones. Does not charge batteries. Battery run time is identical to the 1x9V edition. Higher voltage enables higher volumes for high impedance headphones
Rechargeable, 1x9: Ideal for portable use of most headphones. Adds integrated charging circuitry and includes 1x9V Tenergy low self-discharge NiMH battery. Requires a 10V+ AC/DC adapter (not included)!
"Excited to build my cMoyBB!"
"Hi, recently purchased The Element, must say that it is the best DAC/AMP that I've used in it's price range, in my eyes (ears) it surpasses even DAC/AMPs double it's price."
"I love so much your Objective2!! A masterpiece!"
"@jdslabs thank you for making the element my favorite amp dac combo ever"
"Just great customer service and no nonsense products, just pure performance!"
"Received today the O2 kit, assembled in some time, and, wow, wow, wow!"
"Just got my ODAC, sounds great, this unit is exactly what I needed and what I wanted."
"Just got my first amp. O2. Great, sturdy little powerhouse. It really opens the soundstage and makes audio fuller with my AKG 700s. I had mine customized as well. Great way to make your amp yours!"
"ODAC REV B - is the best DAC (small size) in the market i ever tested, bullet proof design, very reliable, tested on PC/Mac literal plug-and-go."
"Enjoying The Element with my Ether Cs!"
"Very good customer service. Absolutely recommend this shop for high quality audiophile equipment. No matter where in the world you are, these guys will take great care of you."
"Man, @jdslabs has a fast shipping department."
New JDS Labs Element arrived today. Just gonna hang out in my office with headphones all night.
My new cMoyBB head amp just arrived! Looks great and sounds even better!
Purchased a couple devices from JDS. They are absolutely exemplary in quality. I purchased an Element from them a couple years ago and I've encountered zero reason to purchase another DAC/AMP.
"JDS does their job well without resorting to Hyperbole to move product out the door. Glad my research led me to this small company with reasonable pricing, solid products."
Kudos to @jdslabs - not only are their products breathtakingly good. Their customer service and support is equally awesome. Thanks for all the help 🙏
"Just received my objective 2. Everything from packaging. Weight. Material and most of all the audio quality is 10/10. Even was caught off by the esd bag it was contained in. I'll be back for any possible audio needs"
A great sounding combination @TIDAL masters as source, through a @jdslabs #ODAC into @YamahaUK AX392 and finally out of my @TannoyHiFi DC6T
Digital really is stunning when done properly
"Thanks again, @JDSLabs for the amazing O2 headphone amplifier. Very impressed; eyeing your OL DAC now."
"I'm blown away by the sound quality of the JDS Element with the Massdrop AKG K7XX. Smooth and effortless reproduction of all the frequencies with tons of power on tap. Killer amp and DAC! Great job JDS Labs!"
The OL DAC is a remarkable upgrade for me. More transparent. Clean. Real. Even without an amp change. Well done, JDS. Thank you.
"The El stack just arrive today, making the Elear sounding more transparent, love it."
"Arrived this morning.. Brilliant. Simply brilliant. Solid build. Solid sound. Cheers JDS Labs!"
"I have had A LOT of audio equipment over the course of my life, but man my @jdslabs element is my favorite. (paired with @Audeze LCD-2's)"
