Tom Evans Groove+ SRX MK2.5 Phono Stage

The Groove + SRX is a Groove with a severely uprated power supply (larger transformer, increased smoothing caps, and an extra layer of Lithos regulation between the standard unit's internal daughter boards and the mains), which makes a substantial difference.

The four layers of isolation allow a -180dB noise floor. The mains pcb has been replaced by the Lithos 6, a complex class A regulator. Its outputs then feed the dual mono Lithos 7s on the signal pcbs.

The external mains supply box contains a 70 watt transformer designed and manufactured in house. The transformer has an electrostatic screen to remove any RF noise, then rectified, smoothed, and regulated before leaving the box and heading for the Lithos 6. The ultra low noise and distortion of this product provide audiophiles with the greatest possible dynamic range and resolution available.

"The power supply makes instruments more solid, but above all, more natural. It brings the music presence"
Roy Gregory in Hi Fi+. Truly fabulous.

The Groove + SRX is a high end phono stage from Tom Evans Audio Design, featuring several upgrades over The Groove+ SRX makes available the option of user adjustable resistive and capacitive loading. The circuit board incorporating the banks of dip switches for 9 different resistive and 5 different capacitive loads is external t the signal path.

The SRX also includes new front end circuitry (the SR stands for SUPER RESOLUTION) that drops noise and distortion by over 50%, Roy Gregory says, "Swapping from the Groove + to the SRX, the first thing you'll notice is the dramatic increase in sheer substance and colour...What the SRX upgrades do for the Groove is place it firmly back at the top table of vinyl replay. It is also, and by some distance, the most affordable of the various options I see seated there."

Please note: the MK2.5 contains a new output stage, it also contains new Lithos 7.5A local regulator pcb's, a new layout with many sonic improving parts.

Like the 20th Anniversary model below it, the Groove+ SRX features a more sophisticated design with a dual mono layout and dual Lithos 7.4 local regulators, providing an even wider dynamic range giving more lower level detail - almost twice the dynamic range of the previous model Micro Groove+ X - recently measured by an independent German magazine to have a signal to noise ratio of 108dB (A weighted @ 20kHz with 73dB of gain) and that was with our previous 7.3 Lithos version.

However, the Groove+ SRX version has an entirely redesigned circuit with an external power supply with our latest High current 6.1 Lithos PCB. This offboard PSU helps to once again double the dynamic range and half distortion of previous 20th Anv. model.

All of our range now come with selectable dip switches and here we give you a choice of 9 cartridge loading resistances per channel. 112, 126, 144, 168, 200, 250, 333, 500, 1000 ohm are selectable, and if you require a custom load then please let us know.

The gain is set for an optimum level to suit most current cartridges of 0.2mv to 0.6mv Other gains can be catered for upon request.

The new Groove+ SRX mkII is a reality check to all other Phono Stage manufacturers around the World.
