Pass labs upgrade path

I would say you’ll get more out of a preamp upgrade. By the way the volume control on Bricasti is a lot better than I thought it would be when I tried it on my M3.
Just thought to mention it in case you need an interim preamp if you sell before you buy.

   Welcome back. 

Thanks. Good to be back. 

Oy.

It depends how much power you need, how big is the room 

what most people don’t know Thst inside there are many upgrade paths as in parts quality Thst can be bettered  for example  Vishay naked resistors in smaller1/2 watt type , worlds best Belleson regulator's these dramatically lower the noise floor .

ever capacitors ,especially output caps  . For they donot use the absolute best ,that-is reserved for their top efforts. Myself even upgraded the transformer even the internal wiring . It depends how far you-want to go .this is the most cost effective . I have modded everything in. My system and have been doing my own loudspeaker upgrades on the Xovers for years , being an ex dealer , my technicians showed me , and did you know as a rule only 25% of the cost goes into the product on average ,the restR&D overhead and markup including packaging , that’s why modding brings such high sonic  returns for the monies ,that’s how Modwright became so successful.
