O&B Audio amplifiers

[Venkyrenga]

I am looking to buy O&B SS2150 power amplifier. I currently have an Elac dbr62 driven by Audiolab 6000a. I really like the sound but the 6000a doesn't seem to have enough power to drive the dbr62 to their potential. So I am planning to use it as a preamp and the SS2150 as the power amp.

I do not seem to find many reviews about O&B amps online. So I want to hear from you guys. I really like the smoothed over and sweet sounding treble of the 6000a. So it's also important for me that the power amp doesn't affect that.

Not sure of the 2150 but my monos have very clean treble. It is best if you request someone in your city for a listen.

I have been using the SS2150 (upgraded power supply version) for more than one year and am very happy with it. It sounds very neutral to me; that's what I requested from Ankit during the build. I am very happy with it. But recently I asked him about monoblocks, which I am planning to build in the near future.

Check the classified section, Someone has just listed one today for amazing price. I got similar modal in white color for around 32k (including shipping) for 1 year old modal with upgraded caps.

How is your experience with it? What pre amp and speakers are you using?

It is neutral amp, I am using it with Denon AVR 3800h for LR. Also, I haven't heard any other amp but this one is really heavy and seems like built to last longer. I am using it to power Q Acoustics 3030i.

Has there been any noticeable difference in the way the QA 3030i is sounding after switching to O&B from 3800h ?

@Blackstar Honestly I am not sure apart from one thing that is I am sure that it sounds slightly fuller and it have more punch but I think I am not noticing more difference because these QAs are not that huge and I think if I had full range tower speakers I would have noticed more difference.

Wanted to post a short note on O&B and Aniket.

I have been using Hypex UCD amps. Over the last 10 years or so, 10 amps out of 12 blew. Typically their HXRs get damaged.

Out of frustration, I bid adieu to Hypex. Acoustric Portrait was an option but I felt they were over priced.
I heard about O&B in this forum and got 2 4-channel amps from them.

The most important thing when purchasing an amp, IMO, is serviceability. It will blow - either a power surge, or voltage drop or .... It is just a question of when.
A few months ago, after one of the typical downpours of Kerala, I found the 2 amps completely drowned in a pool of water. I had to fish them out. I sent them to Aniket and he was kind enough to test it, dry it and send it back. The only "damage" I can hear now, is a bit of a hum/buzz possibly from the transformer, which wasn't there before.

Last week, the amps again blew. I could see sparks and could smell fumes. This time it was an over-voltage incident. Thankfully, all I had to do was to chip the burnt debri and clean up a trace and the amps were back in business. He had a power supply module that takes the hit in case $@&*$*## happens. Worst case, you replace that module.

Apropos Amp's sound quality, I can't hear any "character", which means it does it job well.

So those of you out there fishing for an amp - I would heartily recommend O&B, for great products and even greater service!

PS: He was offered a job by Hypex, which he refused. That should be some proof that he knows his craft well.

Good man Aniket. Keep going.

I recently purchased O&B Dual Monoblock (DMB2300) amplifier and wanted to share my initial impressions. The amp appears well-built with high-quality components to my knowledge. I've paired it with both my Dali and Linton speakers, and the results have been excellent, especially for extended listening sessions. I'm very satisfied with the DMB2300 and how it performs with these speakers. Instrument separation has been wonderful to experience. Not an audiophile to describe more, so I stop at this point. And yes a word about Aniket for his outstanding patience and very responsive to answer all of my questions.
