Wow gorgeous love the footers, rack
B interesting how it compares to Koda which is awesome pre
One would expect a synergy with the HD amps
Is it SS or toobs?
PS and off blog subject since u have monaco like me, how do u find the VPS ?
Wow. Congrats. I used to have the PLL and VPS. Great pieces of kit. What is the MSRP of the HD preamp if I may?
Howie
John, very interesting change for you moving from the Koda. Congrats.
Very interested to learn more about your impressions on how the two compare.
I used to own the PLL too ! I wish I never sold it and kept it for a 2nd system one day. Plus I've read the Nagra MPS really super charges it (similar to how it helped my VPS) US list price is "gulp" $59,500. Upon first listen to the HD pre you know why they are commanding such a high price.
Curious that I can not find the HD preamplifier on the Nagra site. Do you have the values of input and output impedance in the manual? (Yes, it is a mandatory question for Opus users ...)
I just looked in the manual, it's a "provisional" manual and the finished version to come later. It does not have the specs. My dealer did call Transparent who did contact Nagra on my Transparent Opus cabling. The output impedance is variable with the transformer based volume control. I think, don't quote me on this, it can vary from .4 ohms up to 80 ohms. My Koda was 75 ohms output impedance. So Transparent asked me to try it as is...then as I decide on a normal volume range they may fine tune the cable. They felt anything lower than what the cable is set at is ok, anything higher for sure needs to go back. So far I've never had the volume past 1 o'clock (-10 db on the Nagra HD Pre) so i am under the 80 Ohm max output impedance (which would be +6b on the Nagra HD Pre).
My Magnum Opus cabling from dCS to HD Pre did not have to go back. Koda was 50k Ohm input ....
If you are happy with Koda K 10,was interesting also K 15 that is in the same range of price of Nagra,even if my idea is to have same brand in top amp to have a better sinergy
Thanks. Fortunately the Vivaldi has several output levels, you will be able to easily optimize the best range in the preamplifier for your system. How many steps do you have in the preamplifier volume?
BTW, I found this picture of a sketch of the footers of your new preamplifier during the design project - really impressive.
Congrats John
The Have a pre amp must be out of this world to dislodge your Koda.
Is Nagra going to bring put a HD phono stage?
