I like Vcap Odam much more than Miflex . Just pulled out Miflex and replaced with Odam in my amp. Much better after break in. Everything improved from bass to highs.  More depth, more inner detail…..you get it. Miflex are forward sounding and not ... 
shielded vs unshielded pros and cons?
Point of clarification,“If using the common twisted pair type of IC design, then using all natural conductor coverings like silk and cotton with no shield will sound best in most audio systems. Phono cables must be shielded however.”I should have ... 
shielded vs unshielded pros and cons?
In my builds it is clear that shielding a cable using conventional methods like foils and braided copper tubing closed in and darkened the sound. Unshielded ICs sounded more open, detailed and nuanced in my experience. Now some designs bypass thes... 
Circle Labs A200 Integrated amplifier review - It will appeal to both tube and SS lovers……
If your particular source is built from the ground up to sound best using the balanced outputs, then I suppose it’s possible a little SQ is lost when not using a truly balanced integrated amp. This is the only scenario this would ever come into pl...

Here is a good article on damping factor. Damping factor can impact the control an amplifier has on the woofers. Higher damping is said to better control the bass giving it more articulation and tightness. Folks argue this from many different pers...

The A200 is a dual mono design, but it is not a true balanced design. The XLR input is not truly balanced and there for convenience.

Listening tonight to several artists including Tierney Sutton, Paris Sessions, I was struck by the realism of the music I was playing. The artists were right with me and the speakers just disappeared.  The music was so open and free creating a ver...

@hilde45,Yes, Colin is a small one man operation. As you can see he carries some highly respected brands such as daRTzeel, Tron, Lamm and Cessaro Horn speakers. These highly respected outfits decided Colin was a person they trusted. His site is ve...

@whipsaw That is a very well done review and I love how honest the designers are as well as the reviewer.   
Streamer/Server to replace Innuos Zenith
I did try a Roon Nucleus, Apple Mac mini, Nuc and the Zenith just walked all over them in terms of sound quality.  Now that is based on what sonic attributes are important to me. I value tone and a sense of ease to the music.  I am not a huge deta...

Regarding the output stage, in keeping with the desire to use as few parts/devices as possible the A200 uses just one pair of high current BJT’s. (bipolar junction transistor). The high current steering control stage does work in single ended clas...

@facten I use the Hapa Quiescence C of late as it matches well with my system. I also swap in my Acoustic BBQ  IC.  The Hapa line is very good indeed with real innovation at its core.

@jond You are correct about the output.  My mistake as I was thinking about the Class A preamp section.  The output is indeed class A/B.  My apologies. The technical explanation regarding the output is rather involved and I will ask Colin to expla...

Thanks Tvad. I should also clarify that this amp won’t sound like a SET tube amp in every way. It does not have quite the same delicacy, intimacy and 3D staging. It does deliver in the ways I mentioned in the review. Just want to be thorough in my...

Patience is hard right now. I get it. The sound will go south at around 35-50 hours for a short time.  After this all gets better up to 200 hours or so. They will open up, smooth out and bass will fill in more at full burn in. Just the way it is w...
