     :'(  Just fired up the 5W SECA version , OK power low but I was shocked sounds better than the 30W A/B .
    Detail on classical music and image was amazing, the bigger amp better on TRex "Born to Boogie".
    Hi Dave it will be good on Jazz, so I have to dig out "Jazz and the Porn Shop" sorry not naked ladies Pawn Shop.
    Then try sound track on that movie " Yesterday" or on YT " Hippo Sings Lion Sleeps Tonight" Nephew loves it and he will be 1yr old soon. He loves music , great. B)

    What I need is a 30W SECA. Oops... I already have a pair of them!  :)
  • uglymusicuglymusic
    I'm sure the 5W SECA would be fantastic into a pair of horns.

    Right. Where do I start.?

    The amp we built (joint effort  :)) is the mix or hybrid version, so both P/P & SECA into a lovely little heatsink chassis from Amazon, eBay etc that costs just 50 quid and measures 210mm wide x 70 high and 250 deep. 

    I've had it running for a couple of days now, and three words sum it up. Powerful, refined & poised

    This thing doesn't sound like it looks. The soundstage is wide and deep with excellent tight tuneful bass, expressive mids, and a beautiful shimmering top end. 

    The thing I like most about this amplifier (and this applies to Cols other designs too) is that whatever type of music you are playing, there is nothing in the mix that is forced or aggressive sounding even on poorer recordings, yet every instrument sounds realistic, natural and engaging like real thing. Lovely stuff. 

    Anyway, enough of my ramblings. More tunes required  B)

    From Mervyn.

    "A diminutive kit amp is an excellent example to show off Colin Wonfor's ingenuity and unsung skill as an audio engineer. It is a basic no frills stereo amp with no on/off switch or on light to speak off. I have the 15W A/B class version with an 80va transformer which is in the middle of the range between a 5W SECA pure Class A one and the 30W A/B version (using an 120va transformer). There is also a 5W SECA sliding into 30W A/B amp and the option to add an Alps volume control to all amps making a standalone stereo amp. Ideal for an office or bedroom system but with the right matching gear also capable of producing a very accomplished main rig sound where budgets are tight.   


    Even from cold the staging and musicality staple features off all Colin's amp stand out immediately. Yes it is a little rough around the edges but this is from a brand new amp with no run-in time on the caps or electronics. But despite its mere 15W this amp was capable of driving my Ruark Crusader 2 three way 88db speakers no mean feat without any hardness or strain. The stereo imaging is quite stunning for such a small piece of kit and the famous EWA bass is more than adequate being deep and taut. Resolution is excellent and the amp has a very fluent fast delivery.  Capable of dealing with all music genres it may not look much cosmetically but boy does it sing. Complex classical symphonies are coherent and logical and simpler jazz or folk recordings come to life with rock solid imaging and placement. Equally vocals sound real and alive. Sound staging is both wide and deep giving you a real involvement in the music making and a 'you are there' experience - quite an accomplishment for a small black box. Whilst unfair a comparison with my existing EWA A40 amp does not markedly embarrass the kit amp. Of course the A40 has more a refined sophisticated signature and a more airy sound but otherwise the lower class kit amp holds it own very well. "

    It seems none of the options offered work on Vanilla Forums. I had to hack the HTML code to get them to work.

    I like it. But I'm habitually confused.

    Sometime in the future I need to talk to you about this. But I think I need to build something simpler first.
