usb headphone amps

"You need a high quality headphone to be able to maximize the sound quality this amp produces. ...besides improvment in headphone audio was able to plug into pc usb port and with shielded 3.5 connector to aux in a seperate amp worked as dac to amp speakers improving audio."

"Great Amp For Cave Man Audiophile...So many things that were common on amps and receivers over the last 30 years have been scuttled for this amp. ...great amp. womdeful sound limited on features. no sub out"

"Great! Worked on my headphone amp...My Schiit Valhalla 2 was making noise, and using this fixed it. The amp is now noiseless...I had an old receiver that was producing static/humming from the headphone line out. I put this between the headphone line out and my headphone's 3.5mm jack and the static/humming disappeared (a few male/female conversion adapters were needed to connect everything)."

"The top of the unit has two 1/8" (3.5mm) jacks - one for microphone, one for headphone. Both are slightly recessed, though I doubt your favorite headphones are going to have any trouble plugging in. ...Headphone plug is very sensitive....The headphones must be adjusted frequently in order the hear in both sides of the headphones. "

"still no headphone solution from Sonos; really disappointing...would be fairly easy to add a headphone jack to the amp, or to offer another dodad to connect to Sonos with a headphone jack. ...Sonos Amp...love these sonos amps they sound great easily expandable and priced right"

"Brilliant amp...I bought the PM 6007 amp 2 weeks ago, this is my first ever Marantz & the best i have ever had, i can't get my head around that this amp only puts out 45 watts @ 8ohms (ALLEGEDLY) it is more powerful than that surely, the sound is nothing short of brilliant, it has no problem firing up my 92 dB 180 watts 8 ohm 3 way speakers, i had no idea my speakers actually sounded this great, i do recommend the PM 6007 amplifier, 5 stars, no, i'd give more if i could...I recently upgraded my old Nakamichi amp ( not at all a bad one) and T+A TLS speakers for this amp and Monitor audio bronze speakers. "

"Hi-Fi amp with unmatched quality of life features....I don't even know where to start with this amp. I'll start with the TL;DR. This is one tight little number of an integrated amp that anyone dipping their toes into Hi-Fi in the 2020s absolutely needs to consider. ...Amp...All you need in one amp, connectivity, integration and smart features are all in one amp"

"Amp it up...Excellent powerful amp. It powers my whole house full of speakers with clear sound...Good entry level 2 channel amp...Great for anyone looking for a low distortion amp. Good value for the money. I have had other arcam amps and have been happy with all of them."

"Kicker amp...Great amp and good bass meets and beats the standed...Big things really do come in small packages. The size of this amp was a nice change compared to the big bulky amps in used to."
