Power Amplifier - Maximum Resolution & Detail!


I am assuming some of you have experienced the following.... All else being the same in the chain, you replaced a power amplifier and started hearing more resolution and detail, perhaps a lil more in a track that you have heard a thousand times.

Ime, the higher you go up in price doesn't necessarily guarantee that you could experience the above mentioned. It seems to come down to the nitty gritty of the circuits under consideration, i.e., the black art of power delivery and analog circuit design.

What is a power amp you may have experimented with that provided the maximum detail and resolution at any price? (Not just perceived changes in tonal balance, etc).

I am hoping to shortlist a power amp based on some suggestions here for a future purchase.

 

P.S. If you are an ASR type of guy who thinks all power amps sound the same, this may not the right thread for you, I suppose...

@mbmi  I heard the AVA NP-1 at AXPONA and the system sounded sensational especially factoring in the cost. I own AVA M225s, have you compared the NP-1 to M225s? Would you disclose (or message me) the other amps in your stable? 

@deep_333 My #16 is likely a little less detailed than the 150 and 250. Doug said the 150 has some newer electronics that affect the top end. I think similar to the CODA S5.5 amp (mentioned above) in that aspect.

My #16 works great with the NS5000 in almost all respects, except that it is not an uber detailed amp (some people think it is). I think we maybe after the same type of amp for the NS5000. Since the speaker sounds so good (coherent), I want all the details in the recording to come out of the speaker. That is where my interest for the SimAudio North Collection comes from (an uber detailed amp). 

Doug said that the real magic comes from the $8k Voltage amp that is hooked up to the 150/250 amp. That cannot be used for the #16 amp.

Destination HiFi in LA has the 150 for demo. I never made it down for a listen.

CH Precision M1.1 did exactly this for my system. I was not expecting such a dramatic improvement with just an amplifier change, but it was there.

If maximum resolution and the best circuit design is what you are after, perhaps consider a power amplifier from Gilbert Yeung. No one makes a better power supply and every one is hand built to order, so even if you have any special requests, they can be accommodated. A base set of 150w into 8 ohm monoblocs (300 into 4) would be $14k.
