Exclusive Bass Boost Switch The cMoyBB ships with an internal bass boost toggle switch. Switched off, the original, flat audio signal is amplified. Switched on, bass is increased up to 9.4 dB, just shy of a perceived 2x increase in bass volume. Do-it-yourself builders have the option to substitute the bass boost toggle switch for a bass boost control knob. Printed Circuit Board (PCB) Most cMoys are built on protoboard and use thin wires to transfer the audio signal, making them prone to interference and signal degradation. The cMoyBB v2.03 uses a top-layer ground plane and tightly optimized signal traces, easily outperforming hand-soldered protoboard connections. Proprietary software was used during design of the PCB to check for proper impedance characteristics and negligible crosstalk. Such attention to detail cannot be achieved in protoboard amplifiers, or even in circuit boards designed by most hobbyists. Not sure what all of this means? Check out the cMoyBB reviews. Power System A Texas Instruments TLE2426 precision rail splitter and 25V, low noise Nichicon 470 uF capacitor are used to eliminate the unbalanced resistor divider power system found in standard cMoys. The cMoyBB handles more than double the voltage of most cMoys, meaning the dynamic range of high impedance headphones can be extended even further when using a high voltage DC adapter. Version 2.03 optionally allows for a second TLE2426 rail splitter, giving the cMoyBB more current handling capability than ever! The cMoyBB v2.03 also employs ceramic decoupling capacitors on all IC power pins. Decoupling helps to prevent IC supply ringing, which significantly enhances opamp stability and sound quality. With so many headphones, earphones, cables and headphone amps to choose from, it can help to know what to look for. Check out the website for reviews, comparisons, tips, specs and recommendations!

I recently bought the Audio Engine A2+ and a pair of ik Multimedia iLoud Micro Monitors and the improvement in both of them using this little gem is really breath taking.
Today I'm in the market for a desktop headphone amp or amp/dac and I'm not hesitating to go with one JDS Labs model once I can make a decision.
Without a doubt the best amp for the money.
Using UE900 IEMs with my HTC One
Amazingly, my cMoyBB makes each of those headphones sound noticeably better under those high-res input sources, smoothing out the "profile humps" and allowing those cans to do what they do best. Interestingly, I do not use the "BB" (Bass Boost" switch, as to my hearing, the standard profile is so accurate and bass-worthy as it is - clear with no boom. I'm also constantly trying new headphones now, and always hook 'em up to my cMoyBB for standardized listening, and comparison.
I must also mention, I accidentally shorted my first cMoyBB - John was simply fantastic, a truly nice guy to work with, and he replaced my unit without hesitation, even though in hindsight, it was probably my fault. JDS provides THE best service of any electronics vendor I've ever worked with, and they get 5 stars for that alone! I have also called him and strategized over my internal profiles for each pair of headphones I've purchased - great feedback, and no extra cost!
I'm sure Sony and Pioneer are glad for JDS as well - I went out and bought much more expensive headphones as a result of my joy and satisfaction in using this product - and I still haven't reached its full potential yet. Perhaps a pair of Sennheiser 700s or 800s in my future? Highest product and company recommendation I can give.
