Vfet / SIT Amplifiers

Well I’ve an Absolute Audio Labs SIT-A15 SE power amp being built for me presently. Supposedly greater treble and bass extension than First Watt SIT3 and predominantly negative 2nd order harmonics which should give a more expansive sound stage than the SIT3 also, due to use of Tokin SIT’s. I’ll pair with a icOn 4PRO Unbalanced passive pre and Accurate Ultimate D1000 DAC. The pre has 3db gain and DAC very high output so it should be a favourable pairing. I believe this will be a significant upgrade over my Existing Pass Mini Aleph and 15W rather than 10W is nice also. ;)

mjw25a,

FW_SIT3 2nd harmonic is significantly dominant over the rest of the higher order harmonics. I do not believe that any more dominance of the 2nd would add any benefit. I have studied this quite a bit...on the bench with a proper audio analyzer and most importantly side by side comparison with other vfet amps.

I can't wait for your impressions of the new amp. Based on the few photos I see on the net it looks like a nice project and of good quality too. 

Please share your impressions.

Yes, thought it might be of interest as it’s a current production (albeit very low numbers) amp which can be purchased right now. I believe only about 5 made per year.

Hello guys,

I need your informed opinions please 😊

I will soon acquire an Sony ta-N7b power amp (my dream), it was completely restored about a year ago in Paris Seine et Marne. (excepted big filter capacitors)

I'm also on a second hand speakers opportunity, it's a pair of Pioneer/Tad S-2ex.

Do you know this speakers ?

Would that be a good match with the Sony? 

I thank you in advance.

Friendly.

You're right about the B-2, I'm not sure what condition the amp was in. I need to get her properly restored and redo the test. As for the TA-N7, the C-1 and the B-3s, I was told they were fully restored by my tech bloke, so I believe they really were restored. I can't be sure, of course, but I have no reason not to believe him.
