    You've got a lot of various odd tools, dowel rod and glue on that top.

    Looks like a few projects going on at the same time. ;)

    Hehe. It was originally a roll-top. Filled the holes used to attach the roll-top with dowels instead of putty. :smile:

    I just swapped in my pair of Monarchy Audio SM 70 mkII's to drive the Nola Boxer 2's. I figured it was time to give my First Watt F5 a little break.

    Received and installing the crossover upgrades for the LSi9s. This is the Fortress mod from our very own @VR3 Trey. They look amazing, its a shame they'll never be seen again after this evening :D;) . Treys customer service is great and the crossovers were very well packaged as well, I must say. Pics don't do these things justice when they are in your hands!

    I'm trying to upload photos but I am experiencing technical difficulties at the moment. Trust me I took about a dozen of them.

    They look great, but I am curious just how much of the internal volume of the cabinet they take up, and if that would have a negative impact on the sound.

    I've heard the modified Lsi9 powered on a krell system and I can assure you, it's definitely not negative. 😜

    I asked the same thing. I believe Trey.

    ok, big changes afoot.
    https://nanomesher.com/nanosounddac2/
    It's a raspberry pi direct mounted dac with
    a small front panel display and controls for volumio.
    And it has a remote!!!
    1st couple of minutes sounded BAD!!!!
    After a couple of hours, much better.
    I also had to play with a couple of settings.
    No preamp, just a external homemade passive
    pre (shunt style) to prevent volume mishaps in case
    of issues with the hardware volume control of the
    DAC. Setting changes can put it to 100%, so I always
    have it in line. I was using a audiogd dac via usb before.
    IT's feeding the McCormack.
    Jury's still out, but the sound has really hit a good point.
    I'm hoping after a couple of days it will be equal or better
    so I can keep things simple. My raspberry has a big honkin'
    usb stick with my music in lossless FLAC.
    It's got a very small footprint.
    Some users have hacked the interface for a 7" screen.
    But for now the goal was a small footprint and the ability to
    use the mini remote. I only need the tablet for setting up
    playlists.
    For someone looking for a small rig, you can get a small amp board
    to add on for a small desktop system.

    Remote control stepped attenuator passive preamp.
    That's some high tech simple!

    I loved my Jolida passive pre. Wasn’t a stepped attenuator with Vishay Resistors but still sounded like it should...nothing!

    I'm comparing it the ci audio passive preamp at the moment, not sure why one needs an active preamp after owning these, especially with a decent match between source and Amp

    So what exactly is a passive pre? Just a volume controller?
    Gustard X26 Pro DAC
    Belles 21A Pre modded with Mundorf Supreme caps
    B&K M200 Sonata monoblocks refreshed and upgraded
    Polk SDA 1C's modded / 1000Va Dreadnaught
    Wireworld Silver Eclipse IC's and speaker cables
    Harman Kardon T65C w/Grado Gold. (Don't laugh. It sounds great!)

    Essentially it is an in and a out with a volume knob.

    Some more involved as far as options, the ci audio has 4 inputs, dual outs, ht bypass, etc

    The axiom pre uses a nice stepped attenuator, you can add more inputs and outputs if you like for more money

    Today I figured out how to employ all the tools of the SugarCube and am now able to do everything including the correct track splits and click removal levels. Total time per LP, from needle drop to transfer to hard drive, is about 1 hour. Given that 90 percent of the work is automatic, all I need to do is verify the results and burn the finished work to the hard drive.

    JRiver has no trouble at all identifying the files, and the results are indistinguishable from the original LP. Once I am finished with the transfers, I will sell off my turntable setup and invest some of that feed up cash on improving my DAC...

    Usually an attenuator (resistive or inductive) and - ideally :) - a source selector.
    The coolest ones include remote control, too, for the sofa spud market, of course. ;)

    I used to bristle at such gizmos being called a preamplifier, but since they're installed ahead of the amplifier... no harm, no foul. B)

    IF one doesn't need impedance matching (buffering), additional voltage gain or current drive between source and power amplifier, a good passive can be as good as it gets, IMO. I use one that's built around one of Dave Slagle's older transformer volume control modules (FWIW).

    I probably won't make an immediate decision on that one, maybe by end of the month, I'm evaluating to much with the crossovers and such. I'll have the second utopia back together next week, I'll use them to evaluate the pres.

    I've tried several passives over the years and found that a few of my favorite CDs are recorded at such a low level that achieving a decent volume is nigh impossible. How do you overcome that?

    Short answer -- you can't (other than a switch to a CDP with higher output) without added gain.

    Comment: Your problem strikes me as very odd, though, for two reasons.
    1) CDs, especially in more recent years, tend not to be mastered at low average signal levels.
    2) CD players tend to have high analog output voltage relative to the old "line level" standard.

    That's the down side. If your source output is low
    Or your amp input isn't very sensitive you have a problem.
    My passive is a home brew, direct connection in and out.
    The alps pot just shunts signal to ground.
    The only real fix is to increase the pot value or
    Add a resistor between the pot and ground.
    As far as running the signal through the pot,
    I never liked the result. VR3's pre is as good as passive gets.
