Thanks for Jay Lee and Thomas Tan's great review.
This Willsenton R8 is in hot sale.
Please trust that we wish to sell it at the lowest price.
But something changed, that we have to sell the R8 at a higher price.
Jay Lee make the review on Apr 4, 2020, at that time, the Exchange Rate is about 1 USD=7.1 RMB, but the Exchange Rate is 1 USD=6.5 RMB on Dec 31, 2020, the exchange rate loss alone is nearly 10%, and the exchange rate is still getting worse.

The Willsenton factory had to raise the price in Jan 1, 2021. The main reason is that the Prices of raw materials copper, iron and aluminum increase by 20% to 60% in these months in 2020.

This Willsenton R8, since it is in hot sale, many improvement have been made.
For the packaging, the first version package is small, now it is big a lot and safer.
The Tube cage cover get better too, the finish of first verison of tube cage cover is spraying plastics, current the finish of first verison of tube cage cover is spraying plastics piano lacquer, looks nicer and top grade.

We sell R8 at price $768.68 USD between Apr 4 and Dec 31, 2020. We Raised the price to $800 and $893.18 USD between Jan 1 and Feb 16, 2021.

After we raised the price on Feb 16, 2021, the Prices of raw materials copper, iron and aluminum increase by 20% to 80% again.
We still have not raised the price again.
The Willsenton R8 is well-know, so, we list the price changing note here.
The other Brands hifi tube amplifer raised 20% to 35% already have not note.
I am not sure when or if the Willsenton R8 will raise the price agian, if the Factory Can't bear the cost and raise the price agian, we will note to everyone here.

We hope you can understand and support, and we are sure that the Willsenton R8 will be the best buy tube amplifier none the less at the new price.
