Modwright LS100 vs The followings


I am using a Modwright LS100. I think it sounds quite good, but I am wondering how does it compared to the followings:

1) Coincident Statement Line stage
2) ARC SP10
3) Doge 8
4) Supratek Chardonnay
I listen to SP10 at my friends place, it has a huge sound stage and very holographic. But the price in the used market keeps going up. Given the current market price, I am wondering is it is better to get a current production model.

Would any of this be a significant upgrade to the Modwright LS100?

@Thaluza, 
I do feel the innate differences between the 101D and 6SN7 are at play as factors. Very different tubes for sure.

Hi@gte357s,
Good question that I should have addressed in prior comments. I purchased my CSLS MK II new in 2009 and it came with the Shuguang 101d. This is a good sounding tube at very reasonable cost and is also reliable.

I switched to the Psvane W.E. Replica 101D in 2014. This is a "great" sounding tube.you can hear improvement across the sonic board/spectrum compared to the standard Shuguang 101D. This premium level Psvane is more expensive but IMHO worth the additional cost.

Good versus great , even more air, openness and inner detail and nuance. The Psvane W.E Replica has a fuller more meat on the bone presentation (Relatively speaking) yet remains remarkably transparent and more dynamic. I’ve had them so long I consider them my "standard 101D
