We are coasting in-between new standards taking their full affect currently, so there are plenty of gap filling products out there right now.
To date this year we have seen a great new technology emerging in headphones which is sure to be a huge hit. Keep an eye out for products from 'Psyko Audio Labs' as well as Sharkoon currently and later in the year.
Moving over to sound cards, ASUS has stunned everyone again with the Essence STX backing up an already strong line-up of sound cards in the Xonar range. Right now keep an eye on the Xonar line from ASUS and also on Auzentech who has done solid work with the X-Fi chipset from Creative.
Also noted is a continuing wireless presence in all facets of our daily lives, not forgotten with the release of a great wireless headset from ASUS which offered quality sound along with being able to listen/talk as you walk.
There are still good quality speaker systems out there, but they are mostly 5.1/2.1 or 2.0 at the moment, because those standards are currently a safe bet for manufacturers, especially with the iPod going stratospheric in recent times, creating an emerging demand for speaker 'docks'.
Watch out for imitators and save your cash if you can for what's to come in the next 12 months. If you must buy a set of speakers now, take at look at smaller safer bets like 2.1 or 2.0 systems. Look for Altec Lansing and Logitech for value, as always.
We are on the cusp of a whole new high definition era of 'home audio' emerging now and rightfully so; many people are waiting to see how it pans out before taking the plunge on new first-gen products.
Be patient and stick with companies you know you can trust and watch as several new exciting products begin to roll off the production line soon.
