    Just purchased a pair of Quicksilver V4 mono tube amps, the newest KT150 version. Will be arriving this coming Wednesday.

    V4 Mono Amplifier – Quicksilver Audio

    Single ended
    Input impedance is 100 K ohms
    Input sensitivity is 1.5 volts

    Now need to purchase a nice preamp. Would like to get the most 'bang for buck' by getting a very nice condition used pre-amp.

    On my radar so far is:

    EAR 868
    Audible Illusions M3b or L3a
    Herron VTSP-360

    I have had 2 different AI M3a pre-amps in the past, so I am very familiar with Audible Illusions 'sound'... not sure what is the differences between the AI M3b and AI L3a, besides the M3b having phono stage options and the L3a remote controlled volume?

    No experience with Herron or EAR, but from what I have read EAR, if compatible, may be the best performing?

    Suggestions greatly appreciated.

    Also would like to hear from other V4 owners.

    I have the V4s with KT120 tubes with the AI M3A from 1999 sounds good to me with a sort of long cable run of 21 feet between the two> keeping the source components away from the amps and speakers. My V4s are from 2011.

    The AI M3A sounded great with QS amps. I heard that combo many times. Audio Research is another good choice. I had an SP16 and Silver 60s together in my system for several years.

    Thanks for the suggestions... I went for a new company, 'Zesto' and ordered their 'Leto 1.5' preamp and their "Andros 1.2" phono preamp, looking forward to their arrival.

    I noticed your Profile page says you have a VAC preamp with phono. I would have guessed the VAC would be a great match with the new QS amp. Do you still have the VAC? If not, what led you to make a change?

    About 10 years ago I had some health issues and couldn't work until recently.
    I had to sell much of my audio system to fulfill my responsibilities to my Family...

    Last week I ended up ordering a Zesto Leto 1.5 preamp and matching Andros 1.2 phono stage. Got a very good deal on these, both only a few months old demos, with full factory warranty.

    Anxiously awaiting their arrival :)
