Rowan Williams, Audio Engineer @ Philips Headphones
"Just wanted to comment that I've only had the O2/ODAC combo for about a week, and am astounded by the quality of the sound, and of the device in general. It feels solidly assembled, and looks great on my desk!"
"You made me very happy. I live in the Netherlands and ordered the C5 on the 24th of july. Within 7 days the package arrived. I was really blown away about the speed of the mail, but most of all what was inside the package. What a beautiful little red box....crystal clear sound, so clear you can hear every detail and it adds volume without disortion. I listen with Etymotic ER-4 and with Audio Technica M50. The audio Technica are now my favorites with a fantastic Bass Boost... Keep up the good work!"
"Just received mu Objective DAC. Initial impression is wow, what a tiny little thing. I hope I'm not disappointed. I hooked it to my streaming player, replacing my Ayre QB9, and started listening. Wow. Oh really, wow. This little product sounds just as good as the $2500 Ayre, and perhaps has better bass response. I am completely impressed Thank you for offering such a great DAC at such a reasonable price. Now off to Audiogon to sell the Ayre!"
"I seriously can't get over this DAC. It is so small.. So beautiful. The brushed stainless steel. Oh my. Thanks so much, John. It is indeed a great product. As is the O2. Fantastic little combo!"
"Just wanted to say a big thank you for a great product and excellent service. My cMOYBB arrived within 6 days, which is terrific. I am very impressed with the build and sound quality of this amp. I have a dual chip cMOY from fred_fred2004 and a FiiO E11 - your V2.03 is in another league. Far cleaner sounding, with great timbre, tone, bass and musicality. I am enjoying it immensely."
"I received my cMoy BB amp this afternoon! I just had to take a moment to let you know how wonderful this little thing sounds! I have headphone amps ranging from $150. to $2000. dollars and this little amp rivals the best of them! The sound is great without any break in...can't wait to get 50+ hours on it! Thanks for making this fine product...I will probably order a few as Christmas gifts soon! I'm glad to have a cMoy to add to my collection, and I have a feeling it will be the go to amp over all the other ones! Thanks so much!"
"Wow! Purchased this on the weekend and John shipped it off first thing Monday morning (Priority). Received it approximately one week later here in Canada. First impressions are indeed Wow! A great little product that absolutely hits the perfect sweet spot between price and quality. I don't believe you can find anything to beat this product at this price point. The cMoyBB with my Westone UM2s, iPod Touch and a Line-out Dock cable is a little bit of audiophile heaven for the long daily commute bus rides. Using it without the Bass Boost feature as I find that my IEMs with the proper seal provide more than adequate bass. Excellent quality, great price, fast shipping and comprehensive communications all contributing to a very satisfied customer service experience. Highly recommended."
"What I very much enjoy about the sound through the cMoyBB is its cleanness, clarity/transparency, openness/spaciousness which I find to be very refreshing to my ear and my listening. I've got two home amps and a variety of portable amps (including the TTVJ Portable Millett Hybrid Amp), all of which I enjoy very much as listening instruments. The cMoyBB fills another, and valued/enjoyed, listening niche for me - through its high-quality simplicity - much like well-prepared sonic lemon ice."
"I just wanted to personally thank you for the awesome experience I had with JDS Labs. You have fantastic customer support and extremely fast shipping. They say you get what you pay for, and this is entirely true. While your Cmoy amp may be a tad more expensive than the regular ones, it blows away the competition. If it hadn't been for the Bass Boost Cmoy amp, my Grado SR-225i's would have never been able to come to life! They honestly sounded weak and nearly tinny because my iPhone was unable to power them; but, your Cmoy amp can easily power them and I'm finally able to hear their full potential! The bass switch adds a whole level of "umph" to the sound. A skeptic turned into a full believer - mission accomplished, John!"
"I finally got the cMoyBB v2.02, and I got to say, this amp is really as good as people say it is, just blows my mind how good it sounds with it, I tried the amp with Skullcandy SK Pro Headphones and Skullcandy Smokin Buds (I am a Skullcandy fanatic, what can I say) and with both I really got awesome quality of sound from the device, so yeah, I am really happy for what I got for the price and huge thanks for making such an awesome device, also, the support I got was really fast and informative, so that alone is great!"
"ALL I CAN SAY IS WOWWWW. Like Jimmy Walker used to say, DYNOMITE, off the hook, ready to rumble, it hits the spot . . . I just got a Pico Amp [$299] and your new amps [v2.02] are giving it a run for the bucks . . . Your amp beat all my other amps, the biosciencegeek, the xm4, the penguin tin amp was another failure. The other 16 amps I have are attached to all types of messenger bags. Your amps make the grado rs1's, the akg k701, sennheiser hd650, beyerdynamics dt880, and the denon hd2000 sound like dreams."
"I have only been able to listen to it for a few minutes, but my first impression is indeed WOW. I can’t wait to hear my tunes all day tomorrow. . . . I have been using a cmoy, but the bass boost is very different and while I was very happy with it prior to hearing this, your amp has outstanding sound compared to what I am used to. . . . I always preferred accurate sound rather than artificial bass, but I wasn’t terribly thrilled with the low end the dinky cmoy was giving me. Your unit seems to be a beautiful match with my er-6s and I am for once looking forward to work in the AM."
