extraudio x250t amplifier

Extraudio at the little audio company,

There's an abundance of Class D amplifiers around nowadays, and opinions on performance of these highly efficient designs vary wildly, even when designed well. Most manufacturers will just incorporate off-the-shelf Class D modules and be done with it - Extraudio do not wish to be "run-of-the-mill".

Many who dislike Class D do so because it doesn't sound like Class A or Class AB. To some, Class D can sound a little "thin", lacking that little bit of warmth and smoothness that gives a sense of realism, and prevents listening above a certain volume level.

Extraudio have incorporated elements of Class A performance into their design. This gives exactly what Class D usually lacks, bringing genuine enjoyment to Class D's positive aspects - low noise floor, highly efficient design (94.4%), high level of control, and a fast pace to its sound. For this reason, Extraudio have classed the X250t as Class AD.

Its simple, dual mono design retains signal quality, and the use of high quality components ensures that this amplifier is able to compete with much higher priced models - Paul Rigby compared some of its characteristics with amplifiers of twice its price (read review below).

Extraudio X250t stereo amplifier

The rear panel of the X250T is very simple. Other than the chunky binding posts for the loudspeaker outputs, there are four analogue RCA inputs catering for line level sources. One of these can be used as a turntable input - there's an optional high quality MM phono stage that can be added when ordering. A pair of balanced XLR inputs allow connection of a suitably equipped line level source such as a CD player.

There are no "pre-outputs". The X250T's unique amplifier section is probably one of the reasons you purchased this aplifier for in the first place, so, you're hardly going to want to bolt on additional power amplification.

Home theatre enthusiasts are catered for though. A home theatre bypass is present in the form of either conventional RCA or balanced XLR inputs. 

Upon switch on, the amplifier will cycle through a checking process, confirming everything is fine internally. Switching between the four line level inputs is instantaneous. When selecting balanced XLR inputs or the processor input, the amplifier will once again go through this process in order to make sure nothing is out of place and everything is as it should be, for your peace of mind.

The simple but rather well built remote control is a very simple affair providing volume, power, and mute functions. Rather than using the usual batteries, the X250t remote has an internal rechargeable battery, and comes with a USB charging cable. On a full charge and under normal circumstances, this remote provides about 3 months of use before needing recharging. One quirky aspect of the aluminium bodied remote control is that it uses an RF coil to transmit remote instructions to the unit. Depending on conditions, its working range is anything between 20 metres and 80 metres, for those times when you need to turn the volume up a little from the other end of the estate, and the butler is otherwise engaged...
