Is 40w int. tube amp enough to feed MerlinVSM

Hi all,

I am happy user of the older version Merlin VSMse, where lately I just have an gear change of a German Made integrated tube amp made from LUA Sinfonietta and German Made CDP LUA Appassionato with Cardas Golden Reference cable all around. After the setup of the new system and run-in, I felt the sound is still rather thin, where now I am wonder that 40w per channel power is not enough to feed the Merlin. Any comments will be greatly appreciated.

Thanks.

Before I seeking help and advise from Bobby, I would first like to thanks all for your comment. To give a little more information of my system, my listening room is a 11' wide by 13' long feet room, and my speaker placement is about 1.5 feet behind and side wall so it is about 6 feet apart toe-in. I do have a older version of A/C bam with transformer from 220v to 110v (due to I am living in the far east 15 timezone away from you guy) just put it beside by my CD player on my glass top rack. Please note that I do not have the RC networks and the Z feet.

I am sure is it my personal preference problem of favoring thicker sound or what, as the system itself perform very musical with a very wide soundstage, however I just feel that it is not human enough with the touch sort of feeling.

i have a lot of things for you to do and try that will help you. rcs will make the sound more continuos and smooth if the amp is not terminated with a zobel. the feet will also make a big difference as will the sixth toe mod to change the footer position. the instructions could be sent to you where ever you live. you may also need the proper jumpers and an lignment tool. the distance from the side walls, rear wall and seating position would also help. what kind of wire, single run or internal bi-wire or shotgun?? what interconnects?
regards,

hi michael,
i would move the speakers in to 5 feet 6 inches apart (center to center) to reduce side wall reflections. do you have the alignment tool to set the speakers toe angle?
check on the termination of the amp with zobel or not.
the side walls will reflect much energy and i would damp the immediate and primary reflection points along with the rear wall with a wall hanging or hanging rug. most of what i see are room issues. and i would sit at 9 feet away or more if possible. is the floor carpeted? please also describe the jumpers as you may have an older pair and the new ones are very superior. are the terminals on the speaker edison price music posts or cardas patented binding posts with a single knob.
so in question, rcs, feet, jumpers, listening distance, side wall/rear wall reflections, alignment tool and where you have the bam hooked up. the bam will sound much fuller and more right in a tape loop or between a cdp and pre amp.
the bam has a capacitive input and will sound much better hooked up as i suggest.
let me know please.
