No shipping, please ask!
Power bandwidth (-3dB points) 15Hz to 150kHz.
Frequency response (-3dB points at 1 watt) 1Hz to 200 kHz.
Input sensitivity 4.2V RMS balanced for rated output. (24dB Gain into 8 ohms)
Output regulation Approximately 0.8dB 16 ohm load to open circuit.
But unlike the earlier models, the 610T uses two 6550C driver tubes, each controlling a bank of eight output tubes operating in unison.
6N1P dual triodes and a 6H30 follower. XORUM required in the REF16 series.
Power output is rated at 600 + watts into 4, 8 or 16 ohm loads. Projected tube life is approximately 2000 hours.
The massive, custom output transformer is an ultra-wide-bandwidth design. And, 50% coupling of the output stage cathodes to the transformer yields both higher efficiency and better than conventional pentode or triode operation. Input is balanced only, with separate output taps for 4 - 8 -16 ohm speaker loads.
At the lowest levels are the power and output transformers; on the second level are power-supply storage and regulation; and on top are the input and output tubes. A ventilated top cover with quiet Pabst fans is optional for CE compliance (which runs off a 12V DC supply jack at the back of the chassis).
Most owners want to see the tubes in their glory, and enjoy the benefits of silent convection cooling.
Just as the REF3 preamplifier provides remarkably clear sonic improvements over its predecessor, the REF2MKII, the improvements of the 610 over the older 600MKIII series are just as great, and of a similar quality.
Transient speed, dynamic impact, and soundness are all remarkably improved.
From massive dynamics to subtle nuance, solo voice to massed chorus, the 610T will likely never meet a commercial recording system it can not handle with aplomb and deliver with musical passion - especially when driven by its Reference partner, the Reference 3 Preamplifier.
