Good luck with the tour!  Always great to see these so we can get impressions.  The new 2.5 pcb sounds like a big upgrade

I'm interested in joining this tour.  I was on the last preamp tour which never quite made it.  I am near south Bay Area, CA.

Hi All,

I'm kicking off this tour and will ship out the tour unit tomorrow.

The tour unit is a brand new unit that uses the new V25 board internally and is in every way the updated LDR3.V25 model but for labeling on the rear panel since we are still in the process of fabricating new panels for the new V25 models.

The tour sequence is listed below and kicks off in Florida, then off to a few midwest states, then Oklahoma, Colorado, Washington, California, Louisiana and finally back home to Flordia.

Thank you all in advance for your participation and I look forward to your feedback and any questions.

Enjoy!  :thumb:

Due to some folks being away from home I'm shuffling the deck a little in order to keep the tour train rolling.

WC is up next and will be getting the unit from audiogurujax.

Have a nice 4th of July everyone!

How is the preamp tour progressing? Any comments on the sound?  :scratch:

We got off to a glacial start where the 1st participant kept the unit a long time and then he and the next participant were out of town over the July 4th holiday so shipping was held up and then there was a car breakdown and so on and so forth. That's how you chew up a month. I'm told the unit is on it's way to participant #2. No posts yet from participant #1 although I heard via PM that he was very impressed.

I am actually hoping it gets delayed until arrival some time in September by the time it gets to me.  :green:

Will continue to check in and waiting to hear about people's feedback on this!

I'm sure we can juggle the order around to fit your timing preference.

A quick update on the tour.
After a very slow start we are now rolling with the tour.
WC has had the unit since July 20 and will be sending it onwards to rklein by the end of this week.

  • My finest audio piece ever!!

WC

Well I had a week with the tour preamp before sending it off to rklein. I am currently running everything through a Marantz SR-6005 AVR which serves as a preamp. I am currently changing my whole system around. I hooked up the preamp out to my Pass ACA DIY amps. For inputs I used my Technics SR-1200 turntable through a Vista Phono1 preamp, a Schiit Modi DAC fed via USB from a Raspberry Pi running Volumio, and the Marantz AVR preamp outputs to check out Home Theater Operation. My speakers are Boston Acoustics HD-9s.

I listened to a varied selection of my music which is mainly rock and folk. For the albums I listened to just check out the What are you listening to? thread in the Music Circle.

I don't listen to my turntable all that often since it normally sounds like I am hearing the sound underwater when playing it through the Marantz. So I was planning some upgrades in that area (have a new arm and wiring on order). Playing it through the Tortuga preamp was a definite improvement. The sound was much clearer and more detailed.

Most of the time I listened to ALAC files streamed to the Raspberry Pi from iTunes on a PC. The sound was very clear and detailed, but without the air of sibilance that I experienced with the iTube2 I had in my system for awhile. Definitely made music listening enjoyable.

I tried running through the preamp with a signal from the Marantz preouts as a HT bypass application and set the volume to 99. It worked and sounded great.

I did have a few issues with the unit. If you have an appleTV like I do, you either have to change remote settings or unplug it like I did. The remote worked OK after that. It took me a little time and checking out the Tortuga website to figure out how to operate the controls. Once I got the hang of it, it seemed to work fine. I didn't delve to deeply. I just changed the volume and the switched inputs.

All in all I liked the preamp board and I am looking at picking one up as soon as Morten gets the Uart serial control all figured out and released. I intend to add it to DAC/DSP/streamer DIY build that I am currently working on. I am going to use an Arduino to control the preamp and DAC with an LCD screen and a pair of eductors.

Here is a picture of it in my system:




Morten, thanks for the tour and the chance to hear this in my system.
