I know well Silvercore and Thoress because one my friend was the Italian distributor in Milan for both,so i listen many product and many time.
I think the best product of Silvercore is tube amp 833.
I had passive preamp and trans mc pro.I was near to buy 833 but then he stop the distribution
The passive preamp and trans mc pro are the best product i listen in their categories.
One time i tried preamp at home of my friend with ML 32 and 33,and was better then preamp ML 32.
Less depth and dynamic,but the sound come out from his Wilson X1 more easy and natural.
833 has a sound very transparent,natural with good image.One my friend sold his Audio Note Japan Neiro Silver,i had 2,8 watt with 2A3 and very natural sound and magic mid mainly in the voices,and prefer 833.I think at this price,from 8 to 11K euro,depend on accessories,there is anything better.
Instead the best product of Thoress i think is the phono.Tube phono with no noise,6 inputs where you can ask the company which impedance you need for every input,one can be also MM.
The sound is very natural,transparent,and open,don't seems a normal tube.
Very interesting the possibility of the phono equalization curves,where old records can sound like an OMR if you adjust them
At this price at around 8.500 euro in Italy sure there is nothing better.
Also Integrated amp and mono amp are very good and very natural sound.Not very dynamic and with low power but sound is very good.
2 very good company with top products and a good price
