Description

For the enjoyment of music.  Lot's of changes over the years.  I typically won't buy something unless I can listen to it in my system.   Spending a lot of time recently searching out well recorded and interesting music via hi res downloads.   I have a really nice vinyl collection mostly Jazz and pop.  Digital I'm filling out my classical titles and more modern recordings.  Jan '16

The high required loading for the Allaerts may be a slight issue with a higher gain step-up. If you want to load the Allaerts at the 845Ohm, a 1:10 step up would be too much (ending up at 470Ohm loading). 1:7.5 would be about ideal (with about 17.5dB step-up gain).

Enjoy the Allaerts! I need to mount my MC1B again, as I have been running the Delos instead for the last 6 months.

I am surprised by the low stated gain of the VPS - 60dB including the solid state stage is still not a lot of gain. Good to hear it is sufficient for the Allaerts.

Have you tried using external step-ups (e.g. 1:10 with 20dB of gain) which would bring up the gain quite substantially from the 11dB of the internal step-up?

Jfrach - how is the Allaerts working with your Nagra VPS?

Interestingly I also run both an Allaerts and a Lyra (the Lyra Delos is my back up cartridge). Quite a difference in presentation although I like both.

Regards,

Rene
