So damn hard deciding which tube preamp to buy!

Ok, Mom just approved $25k or so for a linestage tube preamp with a fully functional remote. I must spend within 24 hrs. Please help me.  

The AVM PA 8.3 - Seriously.  With a tube output stage, two sets of RCA & XLR inputs with tone control and the phono stage is $23K.  Add in SS output stage for a subwoofer and it comes in right at $25K.  

This is truly a world class preamp.  It is unbelievably quiet. Neutral to warm and AVM delivers a massive soundstage.  I have had the flagship monos that go with this here and they easily could be mistaken for VAC or VTL gear, just 1100 watts.  It is worthy of the price.  

Know that Udo (the owner of AVM) was at Burmester for a long time and has an incredible track record.  

Within 24 hours...why don't I believe you?

Well jumia, life is full of choices and you must take a chance and take that leap of faith.

S.A.Lab Samson valve preamplifier would be a good choice at that budget: http://en.salaboratory.com/samson-preamplifier.html

S.A.Lab builds all the transformers in house. Separate power supply. Remote. 3 outputs. Balanced and single-ended connection support. Bypass input for your home theater. Available in any real Ferrari paint finish you like. It's great.

Heads up that I'm a S.A.Lab dealer.
