I wanted a better portable amp. I have a CMOY from JDL and it is good. This CMOY is better. At the moment I am using a pair of inexpensive Koss KPH301 from Drop. (with Yaxi pads and better damping pad inside) Straight from my phone, they are a good pair of $30 phones. Replace the pads and redamp them, they are a great pair of $30 phones. With the JDL CMOY, they out resolve my HD595. The issue is that they are 60 ohms and an amp helps, a lot. With this Mayflower CMOY, (You should call it the Mayflower Compact ;-) Everything improved. The bass tightened up and extended even further down. One could now follow clearly defined notes down into the nether regions. The sound stage got slightly bigger, deeper and more forward. The soundstage also got more focused. Although the Koss are still slightly dark, vocals are quite clear and intelligible. I could actually start to understand what Ellie Goulding was singing on the new Glitch Mob album. I could also better hear the differences between how each instrument and vocal were mic'd and processed on whatever I listened to. Sound wise, it is fabulous I have the 1X, 2.5X gain options and at 1X, I was getting more than enough volume off my V10. The downside is that I would like more battery life than what the nicad can offer. I have rechargeable lithium 9V, but it is a pain to get access to the battery. I am currently looking for a different case for the amp for this reason. The Altoids tin of the JDL CMOY allows quick access to the battery, which I see as an important part of a portable amp like this. The battery connector could also be a more sturdy variant. It is a 5 star product, but I did take one off for the battery access and connector. It is in the same price range as the other CMOY but a big step up in audio quality. I like the case, and splurged for the metal knob. It really does look great. The battery issue is something I will live with and work on as the amp is worth having.
Just received my Version 2 headset. I played some music by Yoko Kanno a was pleased by the the clarity of the highs and lows. The mids are flat and the singing voices crisp. These headphones for me have right amount of highs and lows without being muddled or harsh. I use the CMOY amp. by Mayflower to power the headphones and there is no problem pushing these headphones. Very comfortable headphones with the version 3 EarPads and headband. Great job Tyler and his team at Mayflower.
I've been around in audio, and I have only mainly been a guy who will only spend $200 on audio equipment. Otherwise, I usually don't agree with it. So going into this I felt pretty confident, and after seeing Tek Syndicates' stuff with the Audiophile Discussion(in which I still disagree with) I figured I'd buy a Portable Amp for tuning. I am someone who enjoys coloring my sound at times. This Amp isn't intended for that, but if you use the amp, and use a proper EQ Bench for your phone, or device, the Amp will work along with it. Now personally my only issue is the price. I can't stand that it breaches the $90 door with a full package, I heavily believe that $80 is the right spot, and a proper knock on the door to any newbie, and a friendly greeting to the hipster who wants to run his <a href="http://www.amazon.com/gp/product/B001B1QENY/ref=as_li_tl?ie=UTF8&camp=211189&creative=373489&creativeASIN=B001B1QENY&link_code=as3&tag=wwwmayflowere-20&linkId=6ZHBIFIVUK2UCRIM" target="_blank" rel="nofollow">DT880</a>, or <a href="http://www.amazon.com/gp/product/B00018MSNI/ref=as_li_tl?ie=UTF8&camp=211189&creative=373489&creativeASIN=B00018MSNI&link_code=as3&tag=wwwmayflowere-20&linkId=W3TVFKX3ORTJ54CH" target="_blank" rel="nofollow">HD650</a> around town and have pretty sound. All in all, I'd like to see a price change, but I'm happy with the product.
I am fairly new to the world of headphone audio. So I can't give you comparisons with a lot of different equipment offerings out there, but, I will say this. I am currently looking to choose a headphone upgrade from my <a href="http://www.amazon.com/gp/product/B009S332TQ/ref=as_li_tl?ie=UTF8&camp=211189&creative=373489&creativeASIN=B009S332TQ&link_code=as3&tag=wwwmayflowere-20&linkId=U4P6KW4ZFTAGBD22" target="_blank" rel="nofollow">Audio Technica ATH AD700</a>s, so I have auditioned some world class headphones with various amps (Woo, Leimann, etc.) and this little COMY amp sounds just as good as the others in the $600 to $1000 price range. They have made my Audio Technicas come alive. The base is full with plenty of punch, but alway tight and never bloated. The midrange is silky and the highs are sweet. There is lots of separation between the instruments and I am hearing little nuances in the music I wasn't hearing before. This little amp is highlighting my headphones' shortcomings. My desire to upgrade my headphones has increased because of this little amp. I would highly recommend this amp to anyone. It is one of the rare bargains in the audio market. If they make one as portable as this, with a build in DAC, I will buy that as well. From build quality to the sound, it is a great product!
