Hey Cyril!

Great to see you in AS!

It's a great audio forum and I see quite a few familiar faces from AA over here as well.

This was after his earliest effort. You heard his latest version. His amps are more based in the earlier KSA 250 than the later Krell products.

Hey Myles.....Great to see you here in AS!

If I recall correctly, I think that both of BSC Audio's "Classic Series" & "5 Series" fixed class A bias amps are largely based on Bret's experiences with the fixed class A bias amps from the Krell KSA line (KSA 50/80/100/200) as well as the Krell KRS line (KRS 100/200), as opposed to the Krell KSA 250 fixed class A/B high biased amp or the Krell KSA 300 variable/sliding class A bias amp.

Good to see you on the Shark Philip... And thanks for all of the great comments, I did enjoy our time together immensely. I noticed elsewhere you were at the HK show? Did you manage to see the L5 Pre-production prototype in HK? Hoping you will attend 2015 CES? Let's chat soon.

Hey Bret,

Yep, I certainly had a blast when I last saw you in January 2014, and looking forward to spending time with you again come 2015 CES.

Actually, I did in fact get to see your pre-production prototype 5 Series L5 preamp at the 2014 Hong Kong High-End Audio Visual Show (8 to 10-Aug-2014), and it looked great.

Just like your amplifier, your L5 preamp was built like a tank and its aesthetics were bold, unique and positively eye catching. I have to say that there was certainly a great deal of entralled/enthused chatter amongst the show attendees regarding the amp & preamp aesthetics, and they sounded great despite the less than ideal sonic environment at the show. BTW, I also heard that your H.K./China distributor was receiving quite a lot of inquiries!

In addition to the L5 preamp aesthetics, a lot of attendees really liked the 3 chassis configuration all on 1 base, as well as the 3-band tone controls which many felt would be ideal given the sometimes small an odd-shaped listening environments over here in Asia, in addition to the fact that the tone controls could be entirely switched out of the audio circuit.

Pics look great snoopster, many thanks for the kind words. We will talk soon. B
 
I like threads like this. They serve to let me know what is out there in the sense of names to look at. (Not just me of course, many folks).
For me, it's nice to know whenever I need to replace my amp/receiver or something which with any luck at all is once every 10 years and with very good luck, once every 20 to 30 years.
What I really need is for someone to come out with a publication of some sort describing the different classes of amps and the differences pro and con between them in easy language because I would not know a class A from a class B, D or any other letter of the alphabet. Now there is the addition of SET amps which to me could stand for Search for Extraterrestrial amps for all I know.:)

These amps have black black backgrounds while taking micro dynamics to a whole new level. Bass is detailed, tight and fast. Vocals are to die for. Heat, so far, knock on wood, has not been an issue. The four boxes do not get more than warm.

The synergy with the Strads is as good as I remember it when I had Strads and Pass XA160.5's.

And the XS preamp is also outstanding.

Everything is breaking in - so I will update as time goes on.

But these amps are freaking amazing!

It's all about synergy Kev. If you recall, I experimented a lot with the Strads my first go around with them - and nothing could touch the Pass/Strad synergy. This included the infamous 2301's (which I still love and would like to own again one day....but after the XS150's, not sure why.) Those that heard it at my house, were amazed and some even sought out the combo for themselves.

The XS150's (and XS preamp) reduce background noise to inaudible levels, reduce any hint of grain, tighten up the bass, have wonderful PRAT and add a level of sweetness which is very nice indeed!

As I understand it, the a First Watt SIT-1's were used as the starting point for voicing the XS amps (a process which took Nelson and his team over 3 years). The SIT-1's are voiced very closely to world class SET amps.

At first listen, I can say the XS amps give me the magic of some of the best SET amps I've owned and heard, the power and control of solid state, with a dash of other magic not associated with anything else.

I'm hesitant to say, because no amp is perfect, but these appear to do it all.
