JDSLabs CmoyBB Headphone Amplifier [MOD-4]


JDS Labs’s success is due to cMoyBB’s legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass increases up to 9.4 dB for a perceived 2x increase in bass volume.


Older cMoys use thin wires or protoboard to transfer audio signals. cMoyBB uses a carefully designed PCB with attention to detail that cannot be achieved in protoboard amplifiers, or even in circuit boards designed by experienced hobbyists.


cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters. The result is over 200% higher power handling than the original cMoy! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality.


cMoyBB’s power input jack allows you to power the amp from your desk. Optional charging support also provides convenient, integrated 9V NiMH battery charging.


cMoyBB is cased inside of a brand new Altoids ® Peppermint tin, protecting the circuit from some forms of external EMI / RF interference. You may choose between two tin styles: Peppermint or Wintergreen.


Specify your headphones during checkout and we’ll optimize gain, bass boost, and output power for best performance with your headphones. A technical summary ships with each custom cMoyBB.

    5 out of 5 Improvement-nya Berasa

    Waktu itu saya langsung beli Mod4 kemudian ganti opamp ke AD8397ARZ.
    Untuk kabel m2m saya menggunaka HFS Custom Cable tipe Fast.
    Sesuai dengan ko Mike punya review: Black Background, Bening, Bersih. Dan volume makin gede, jadi muterin volumen cm dikit aj sudah gede banget di Headphone Phonon.
    Ga sabar untuk upgrade lagi ke MOD 5, ayo ko Mike ditunggu :)

    5 out of 5 Kotak Permen Ajaib

    (verified owner)

    Awalnya saya ragu apakah sebuah amplifier akan mempunyai pengaruh yang signifikan terhadap sound quality. Namun, setelah saya coba demonya di hfs, saya menjadi 100% yakin saya butuh “kotak permen” ini untuk menjadi pendamping hidup Phonon SMB02 saya. Terima kasih Ko Mike yang sudah bereksperimen dan ditunggu MOD5 nya!
