Amp for lightspeed attenuator? = $1000 used

Thanks George. Since you recommended the burson-100, did you have any thoughts on the burson ab-160? The specs look as you suggest:

http://www.partsconnexion.com/burson/ab-160.html

Input impedance: 500 KOhms
Frequency response: 1Hz (-0.3dB) to 35 kHz (-1dB)
Signal to noise ratio: >120dB at 0dB gain
Output impedance: line out 15 Ohms @ line level
Power dissipation: >10W, internal, regulated power supply
Maximum Output Voltage :12VRMS
Maximum Input Voltage: 6VRMS

Yes, the Burson AB-160 will work just as well. It's just the newer (and ostensibly better) version of the old Burson 100 buffer.

Dddrrreee: Trouble is I think the 160 has a lot of gain, and a volume control that has to be bridged out so the Lightspeed can shine through, the whole reason is not to have contacts (volume pots)in the signal path. The 100 is better if you can get them to make one or a kit.

George, when you refer to the volume control of the 160, are you referring to the front dial or the 3 dB / 6 dB selectable gain? If the front dial, it's just used for input switching.

Oh, ok then then all you need is it set it for 3db gain, and if you can bridge out the rotary input switch, it's not as bad as having a pot in the signal path, if it's a dual leaf switch (that is one leaf either side of the wiper). If single leaf then bridge it out and only use one input.

Cheers George
