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!

Another thing to note is the cMoyBB seems to distort more at higher levels than my e11 at the same volume levels (which leads me to believe it's the fault of the amp rather than my speakers) but you can't go wrong with either e11 or cMoyBB. ### ⭐⭐⭐⭐⭐ My cleanest, purest most delicious - sounding amp *by B***K on Reviewed in the United States on July 22, 2015* I have purchased, and regularly enjoy, the sound of my favorite music played through a carefully chosen set of headphone amps. Most of those amps cost me many times the price of JDS Labs CmoyBB. What keeps the CMOYBB in its high place in my collection of music - listening instruments is the cleanness and sweet purity of the sound that comes through it. Sure, the more cultivated and "high-fi" sounds through my other amps are ones that enjoy tremendously. And, there's something so suave about the elegant simplicity with which the CMOYBB presents the sounds of my favorite music. With many of my really favorite pieces of recorded music, I don't consider myself to have "really heard them" until I hear them through the CmoyBB. Recently, after eight years of distinguished service in my workshop of listening tools, the CMOYBB stopped producing sound. Within 24 hours, I purchased a new one on Amazon. In the years since I purchased my first one, the CMOYBB has lost none of its clean, simple elegance that has kept me coming back to it again and again. One of these days, I'm going to have to try one of the later amps created by JDS Labs as well. But that is certainly not any indication of any dissatisfaction with the CmoyBB. ### ⭐ Piece of JUNK! *by R***E on Reviewed in the United States on January 3, 2014* I got mine directly from JDS Labs.To make a long story short. These amps don't come close to living up to the hype on the JDS web site. In JDS Labs favor they did replace the first 24V amp that was defective with another amp. But the replacement they sent was also defective. The third amp they sent went directly into my junk drawer, unopened still wrapped in the aluminum foil.. I plan to give it to someone I don't like. The money back guarantee is a lie. I dealt with JDS defective products for much less than a year, yet they refused to refund my money when I asked, instead sending me one more no doubt defective amp to replace my second defective amp. Stick with Fiio headphone amps. Fiio portable headphone amps are quality. Unlike the JDS junk. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/5888864-jdslabs-cmoybb-v2-03-headphone-amplifier-headphone-amplifier-normal-model](https://www.desertcart.tn/products/5888864-jdslabs-cmoybb-v2-03-headphone-amplifier-headphone-amplifier-normal-model) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-09*
