You will be amazed at the precise detail and excellent soundstage produced by the Omaha 300B. It reproduces a vast sense of space with a wide and deep forum. Beautiful in appearance, the 300B tube integrated amplifier represents a sonic miracle of sorts. It represents the perfect amplifier for listeners who wish to connect emotionally with their favorite music.

The chassis is constructed from the non-magnetic alloy to prevent anomalies caused by any magnetized areas. Omaha incorporates high quality printed boards and components which are designed for high-end audio applications. Point-to-Point wiring ensures shortest path to critical parts.

The Omaha 300B integrated amplifier uses a pair of 300B (300b-98) power tubes that operate as a single-ended triode (SET) and delivers up to 10 watts per channel. The 300B triode is an excellent output tube with remarkable sound. First introduced by Western Electric in 1935, the 300B continues to be very popular with audiophiles around the world. These tubes have low distortion and are used in high-end audio amplifiers designed to achieve high sonic performance.

Until now, the high cost of a 300B SET amplifier, sets these types of fine audio products out of the reach of many. The Omaha 300B is designed to produce superb accuracy in sonic reproduction, excellent soundstage at an affordable price.

Whether you are just starting and want a superior, but affordable SET integrated to build a high performance system around; or you already own an ultra high-performance system and would like to explore what's possible on modestly priced SET’s, you will not be disappointed with the Omaha 300B. This is a winner!

WHAT DO THE REVIEWERS SAY?

I noticed the intricate machined prototype footers beneath the Omaha tube integrated amplifier and the conversation quickly shifted to vibration absorption, as this happens to be a favorite pursuit of my own. The Omaha OD-300B is a single ended triode integrated amplifier designed in the US and manufactured in China…It did a wonderful job powering the very handsome stand mounted loudspeakers that were also an Omaha Audio prototype……”.


“Much as we love expensive gear that we (and perhaps you) can dream about, we also like to run across affordable products that can make real music. That's the case of the Omaha OD-300B, an inexpensive single-ended tube integrated amplifier. It was feeding a rather nice pair of stand-mounted speakers whose name we tried, without success, to make out. In fact, they are prototypes, and they are made by Omaha….”

Omaha made their debut only four months ago, at the 2007 Consumer Electronics Show, and so are still a lesser-known quantity in hi-fi circles. After visiting their room and seeing their product line, I don’t imagine this situation will last long. One of Omaha’s smartest-looking pieces was their sleek OD-300B, a single-ended-triode (SET) integrated amplifier that employs a pair of 300B vacuum tubes to produce 10Wpc.”

“Omaha was showing this nifty little 10 Wpc No.OD-300B integrated amplifier, which was driving Omaha's Omaha Speaker. Do I need to say that the No.OD300B uses a pair of 300B tubes? The system sounded warm and spacious. 10Wpc may not sound like much, but the Omaha speaker seemed comfortably driven. Fit' n 'finish was impressive.”

“I heard this integrated amplifier at Home Entertainment 2007 and, at that show’s “Ask the Editors” session, advised showgoers to go hear it. This is w h a t s i n g l e –e n d e d t r i o d e ( S E T ) t u b e sound is a l l about. “The best value of vacuum tube amplifier in the world,” claims the sales literature…

One of the best, for sure.

…Yes, the OD-300B could have had more resolution. The focus was slightly soft. I thought the top end a little closed in—or topped off, if you will. But these are mere quibbles about an amplifier that is so affordable—and musical. It’s about palpable presence. Having the performers in the room with you. SET can get the music closer to you, so that you are closer to the music. It’s not so much that you’re there; the musicians are here. In the room with you. Highly recommended!”

POSITIVE FEEDBACK ONLINE - ISSUE 34

This amplifier would be excellent for folks with slightly bright systems or listening rooms, or with other components that perhaps make the music sound "etched". It is also suitable for systems with monitors and separate subwoofers, as well as single driver speaker systems where the speakers themselves do not go to the lowest octaves. Given its combination of price, aesthetics, quality build, and overall sonics, I strongly recommend the OD-300B. Akhilesh Bajaj
