has anyone received a copy of the circuit diagrams yet ?
Usher R1.5 should I buy?
Hello all, I thought this is one forum where I should ask and take the approval of all the experienced souls here before I pull the trigger today or next week satday. The Question is should I buy the Usher R1.5 , is it as good as the press says or the reviews here or around the web suggests.As for speakers I have a Mission MX5 for now with Denon PMA1500AE /DCD1500AE/TU1500AE as amp CD and tuner with Chord cables. This is the cheapest power amp I can afford at the moment , that too class A till some watts. If anyone has any encounter with this amp please advise me. I listen to only RocknRoll and very little Jazz ( read Norah Jones , Diana Krall) buy it's always Queen and Ledzep , Floyd GnR, CCR,GFR,Lamb of God Korn , Blue Man Group, etc etc. I'm a SACD enthusiast,s o no vinyl in the mix. Love warm rich lush and not forward sounding gear. Please advise if the Usher is good enough as a power amp.

I have not received schematic. I have sent PM to the parties requesting. Hope all is well with vvvinashhh. georgehifi posted a fairly small resolution schematic here: http://www.diyaudio.com/forums/pass-labs/55067-usher-amps-lookalike-buildt-licence.html#post616009 less then desired; however, provides enough information to figure things out. I have an Usher R 1.5 incoming replacing a Classe Audio DR-10 which are driving VMPS RM-30 speakers. With my gear I like to have a schematic if anything goes wrong. PS: Good input from vvvinashhh on factory bias of the R1.5 is 500mA. In that same post I provided above there is a good discussion on process to increase bias. |
Hey Guys, Just wanted to share that I have the Usher 1.5 amplifier in my reference system right now. The amplifier was re-biased by the individual I purchased it from to a higher class A bias. This amplifier is wonderful! It easily is on the same level as highly regarded Pass Labs pieces and drops tons of current to really control bottom end frequencies. It's overall a touch warm/full with a sweet top end and great overall dynamics. The build quality regrading internal parts and chassis are excellent. This amplifier is a real "sleeper" when it comes to cost vs performance ratio. |
Hello All, I have recently purchased Usher 1.5. I like the quality of this Amplifier, especially in the vocal and bass area. I felt Highs are bit rolled off and need an improvement. I have figured out Power capacitor change in Usher 1.5. Which will be the best-suited capacitor? Changing these capacitors will improve sound quality? It is believed that Bias setting in Usher 1.5 needs to increase for better performance. If true, please let me know how to change the Bias setting. Please also enlighten me about other modification can be carried out in Usher 1.5. Many thanks in advance. |
