There are many solid state recorders available with balanced inputs and phantom powering but its important to choose one with a good pre-amp and a clean phantom power supply that doesn't produce interference of the input signal. Another important factor to consider is the quality of the headphone output for monitoring purposes

Telinga have run exhaustive tests on many of the currently available machines and have found that most of them actually fail in one or both of these necessities. The only one that comes near to the specification of the Telinga Pro 6 is the Fostex FR-2LE
(the LE bit is very important) and so Telinga now recommend this as the only semi-professional recorder of sufficient quality for anyone that owns or is considering buying a Telinga.
