How much power does the Rogue Audio Stereo 100 have?
The Rogue Audio Stereo 100 delivers 100 watts x 2 channels into 8 ohms.
Does the Rogue Audio Stereo 100 use vacuum tubes?
Yes. The Rogue Audio Stereo 100 is an all-valve amplifier: vacuum tubes do the amplifying from input to output. It runs 4x KT88 output, 2x 12AU7, 2x 12AX7 input.
How long do the tubes in the Rogue Audio Stereo 100 last?
Output valves are a consumable. In normal domestic use a set lasts somewhere between about 2,000 and 5,000 hours - a few years for most people - and they degrade gradually rather than failing outright. Input and driver valves last far longer, often the life of the amplifier. Note that the tubes carry their own warranty of 6 months, separate from the amplifier itself - valves are almost never covered by the main parts warranty.
What speakers suit the Rogue Audio Stereo 100?
A valve amplifier is judged on the speaker's sensitivity, not just on watts. At 100 watts, the safe rule of thumb is a speaker of about 88 dB or better - an insensitive speaker will run out of headroom long before the amplifier sounds bad. It also has 4 / 8 ohm output transformer taps. A valve amplifier has no minimum impedance the way a transistor amplifier does; you match the tap to the speaker, and a speaker whose impedance swings a long way will shift the tonal balance slightly because a valve amplifier follows that curve.
What amplifier class is the Rogue Audio Stereo 100?
The Rogue Audio Stereo 100 uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the Rogue Audio Stereo 100 have a built-in DAC?
No. The Rogue Audio Stereo 100 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the Rogue Audio Stereo 100?
No. The Rogue Audio Stereo 100 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the Rogue Audio Stereo 100 have Bluetooth?
No. The Rogue Audio Stereo 100 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Rogue Audio Stereo 100 have a headphone output?
No. The Rogue Audio Stereo 100 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the Rogue Audio Stereo 100 cost?
The Rogue Audio Stereo 100 has a manufacturer's list price (MSRP) of $4,195.
