Hi, Sun Jigglet here.
I'm looking into purchasing a $50 CMOY amplifier on ebay (the ones built by "ampedup77", in particular), and I was wondering if they are well-built/ of acceptable quality.
Here's the link: http://www.ebay.com/itm/18V-CMOY-RA1-JRC4556-Headphone-Amplifier-Tiger-Perfect-for-Grado-Sennheiser-/170841459592?pt=LH_DefaultDomain_0&hash=item27c6f1cb88#ht_3997wt_1185
I'm also looking into the crossfeed circuit "ampedup77" is selling (Link: http://www.ebay.com/itm/Natural-Sounding-Crossfeed-for-CMOY-Or-Any-Other-Headphone-Amplifier-/170841158243?pt=LH_DefaultDomain_0&hash=item27c6ed3263#ht_500wt_1202 ). Could I get some opinions on these as well?
If anyone has had experience with "ampedup77"'s CMOYs (and/or the crossfeed circuitry), please do tell me about your opinions as they are much appreciated. Any tips and opinions on CMOYs (or portable headphone amplifiers in general) and crossfeed would be equally appreciated..... Educate the newbie!
* Please try to focus on sound quality and build quality/durability for now. Thank you!
** I do have some questions regarding the CMOYs sound.. do they (in general) have a bias a certain area? Are the focused on the lows, the mids, or the highs? How do they fare with the Porta Pros (I'm looking into these popular phones as well)?
*** Can the mentioned crossfeed circuitry work (sufficiently/ in a satisfying way) without amplifiers?
edit1= Found out the CMOY amp I was looking at wasn't $20 after all (it was on an auction)! "ampedup77" is selling the same CMOY for $50 on immediate purchases. I editted the CMOY ebay link and "around $20" to "aound $50".
edit2= Would these ( http://www.ebay.com/itm/18V-Cmoy-portable-headphone-Amplifier-Audiophile-Sound-Cool-Stuff-All-Accessory/110878819663?ssPageName=WDVW&rd=1&ih=001&category=112529&cmd=ViewItem#ht_500wt_1202 ), and these ( http://www.ebay.com/itm/Cmoy-Classic-Headphone-Amplifier-Texas-Instruments-NE5532-variable-gain-Red-tin-/190641325342?pt=AU_Electronics_Audio_Amplifiers&hash=item2c631bc51e#ht_3729wt_1143 ), and these ( http://www.ebay.com/itm/Bass-enhanced-Natural-CROSSFEED-Acoustic-Simulator-for-CMOY-headphone-amplifiers-/190657483815?pt=AU_headphone&hash=item2c64125427#ht_3035wt_1139 ) be any good?
