Puriss A1000A. Class A amp for serious listening

[entsurgeon]

Checkout the size of the amp in relation to the dvd player and the ipod

And the wall socket and the 5" deep drawer.

I have requested Mr Jha-ji via pm to consider some listening session for Delhi/ NCR audiophiles. Maybe at Sid's place. Waiting for his response.

Maybe after he makes a slimmer & lighter version, this could be possible, as shipping this Beast in current avtaar would be a Task in itself

Akshay pls do so ASAP for many would be glad to listen to your creation

I have a question.
Do a CD player or a pre-amp have output stages based on Class A/ Class AB?

To get the best out of a Class A power amp should the source output stages in the chain be based on Class A?

My understanding is if the source audio signal coming from a Class AB output stage then it will already have crossover distortion in it and just gets amplified going through Class A power amp with the crossover distortion induced from the source.
May be what I asked is a dumb question

Sorry mate, would have been nice to meet you....if only I had known.

Hey, Santosh and Amit came on consecutive days and not the same day. If you check Santosh's post, it has been done on the earlier day.

Yup, I am planning to work on the A600A soon. As rightly pointed out by denom, it would be quite a task sending this amp.

The performance of a system is as good as its weakest link. The pre-amplifier, if present in the chain, is of great importance and it should certainly be class A, preferably a discrete design. However that doesnt mean that every class A pre-amp would sound better than any class AB design. The design would decide what sounds better. However a pre-amp designed to match with a power amplifier is the best bet.

There is no such thing as Class for a source. The classification into A, B, C, D is only for amplification.

I dont have technical knowledge as some other members here but in some websites I have read that the CDP has a Class A output stage

I think its the output stage what Ravi is refering to

Venkat, Ravi's question was about the output stage and a CD player can definitely have a Class A output stage.

That is because this particular CD player incorporates a linear amplifier inside the player, and the Class A refers to the amplifier and not to the player.

Hi Akshay,

This looks absolutely great, and totally professional (btw, I'm the guy that bought your old Sansui integrated).

Do you have a 4 ohm resistive reading for the amp, when used as a monoblock, by any chance? Just wanted to know if it doubles the wattage into 4 ohms..thanks!

Hey Abhijit,

Great to hear from you. the amp o/p at 4 ohms is 90watts continuous.

Cheers.

 

[abhijitnath]

Am slightly lost..I thought as a monoblock using balanced ins, it pushes 100 wpc into 8 ohms per channel. What would be the corresponding 4 ohm setting?
I'm guessing you mentioned the 4 ohm setting in stereo.

Sorry to have misunderstood your question. The power o/p at 4 ohms, used as mono-block would be 180watts continuous.

Brilliant. Will stop by one of these days

Hi Abhijit,

Do drop in sometime soon as the amplifier is due for delivery soon and would not have another unit for auditioning immediately.

Cheers.

Kanwar, I am moving (have moved) all your posts and related posts to a different thread. These posts were seriously derailing this thread. You and others can continue the discussion there. The link is http://www.hifivision.com/amplifiers/16623-should-amplifiers-transparent.html.

Please do not add any of this discussion here. BTW, there are many threads that have already discussed this in detail.

Cheers

does it mean this thread is closed?..

No. What it means is that this thread is limited to discussions on the Puriss Amp. The pros and cons of amplifiers per se, can be discussed in the other thread.
