Hello Lloyd,
Welcome to Audio Circle.
I recently posted a system which includes the Adagio EXtreme speakers, ModWright SWLP w/ tube rectification, Level 2 Custom Jolida JD100 CD player and Acoustic Solid table. (The SWLP will be here in the morning and will take over the duties that the SWL 9.0 and modified Jolida phono stage have been handling). The amplifiers I have been using in this system have been a modified version of these KMP-60 amplifiers but not to the full standards of the Bella 60. The KMP-60 was the platform for my Bella EXtreme 60 units as I will be having the ASL factory OEM the chassis for me (much later in the year) as the KMP has been discontinued in the US market.
I would not recommend them in stock form as they do require some modifications to bring out their potential. We have discussed the Bella 60 amps but it is hard for me to describe the sonic characteristic of the 6C33 tube.
I truly like the sound of the Bella 60's but then again, I have voiced them to fit within
my "house signature" to fit in my lineup. I have also been using these, in rotation with some other amplifiers in the Bella EXtreme line, to voice the EXtreme Adagio speakers. I am in teh process of finishing up a pair of full Bella 60 to be used in this reference system with teh chassis made of African Rosewood. YOu have probably seen the pictures on my website on the Bella EXtreme 60 page.
http://www.bellaextreme.com/bellaextreme60.htm Starting tomorrow, I will be running the same ModWright SWLP w/ tube rectification and EXtreme Adagio speakers that you will be running in your system all sitting on the same Sistrum rack that you should see by the end of the week.
Give me a buzz tommorw and we can further discuss the Bella 60 amplifiers and what they bring to the table.
