Titan 2000 what do you think about this amplifier

destroyer X · 9th June 2008, 08:28 PM

I would like to know opinnions about.

I think it is too much complex....i have suspections that may not sound fine because of double simetrical into the input.... the ones i have tried into my house, made this way, have not sounded fine to my ears.

What do you think.

Files are big.....but high resolution.

And the amplifier is extremelly interesting.

regards and enjoy folks.

Yes, to complic.but nice.

Btw. do you have schematic or SM. for Peavey PV-1.3K

A bit like current feedback NAD 372, nice one.
I bet that if stable it will sound more than nice.

Open loop bandwidth of 53kHz,enough???

I'm no engineer, but isn't this basically a Le Classe A with extras? Some cascodes, buffering, regulated supply and CCS.

or not.... i have some suspections that will not help sonics... but as i have not listened ... so....i cannot know the way it will sound.

I can imagine... because of the input style (alike Leach).... the double simetrical design..... i dislike that sound.... i could listen in many amplifiers using the idea.... not good to my ears....BUT.... in my country almost all amplifiers are copies of Leach Amplifier, using the input differential topologie...double simetrical input... double complementary differential amplifiers...here they use zeners (27V) to control the voltage to them.

I was curious.... will not assemble to listen.... too much dense...too much complicated... a very hard work only to kill my curiosity about... reason why i have posted...maybe someone could have listened or assembled.

My schematics are the same you can find into Jan Dupont site...i use to download my schematics there.... and the ones he had not i have already sent to him.

Carlos

I've built it long ago and it's collecting dust right now.
Which doesn't mean it's not a fine amp.
There's a thread somewhere with a few pictures of the naked amp.

Very powerfull and pretty good sounding but a bit outdated compared to a classD amp.

That is big!
Too big for me.
I mean, 7.65 MByte of file download.
That is juust too much for me, Lineup

I've fiddled with a more basic current feedback, le Classe A alike headphone amp. I recently changed the input bipolars (BC550/560) to JFETs (2SJ74/SK170). I've also tried 2SA970/SC2240. Changing the input transistors, together with emitter resistors and some other resistor values to get proper operation, changes the sound a lot. Where the bibolars are clear and analytical (especially the Toshiba's), the JFETs are warmer, more "musical" and a bit grainy.

Carlos, did you ever try JFET input in a symmetrical amp?

Netlist, when you call it outdated, what do you mean? How would you describe it's sound, what sonical flaws did you find?
