RIP, Paul... I learned a lot from you!

Pancreatic cancer does not have great recovery rates... very sad!

Life is too short! Enjoy every day!

NY Audio Rave / Paul Kaplan - passed away
« Last post by Levi on July 15, 2019, 06:53:21 AM »

Hope you are all well.

It is of deep sadness to learn that our long time friend Paul Kaplan has passed away.

Martin has informed me yesterday that Paul has been battling cancer.  This is all I know.

Sad news. 

Thank you,

Wondering the other day if you had a chance to do anymore work on your speakers?

Just curious.

Another update concerning my system improvements etc.

First, one of the gents had to have a hernia operation, so he could only bring his $4,000.00
Lampizator DAC. He loved the system with the Lampizator, so the Modi 2 needed some
more modding. Such has been done, and is much improved.

Besides the power supply caps being replaced (one is not polypropylene), and output
capacitors (originals are polyester/mylar) to polypropylene, I replaced the stock jacks
with Vampire all copper jacks. All three made a substantial improvement. Near world class dac.

Dan came up and loved my system. We are now looking for an output capacitor
since the one's I am using have not been available for some time. Looking at two brands that
could be promising to modify his possible Modi 2 as well.

So the weakness in my system was the source. The computer, NAD 521bee with analog section
bypassed still doesn't make it. But the modi 2 is really beginning to sound world class.

Maybe I will get more into the NAD and see what else can be done there.

Amplification and Preamplification / Re: Watts vs Current
« Last post by steve on July 14, 2019, 08:21:27 PM »
I'm a complete novice when it comes to anything electric so am asking.
What makes a low wattage amp high current? And is a high wattage amp
high current in order to be high wattage or can you have a high wattage amp
with low current?
Just trying to figure something out. I've been told that a high current amp is good.

ps: If this has been discussed before, please point me in that direction

Hi Don,

I believe many prefer higher current as linearity improves at lower current levels.
I say this because for just about any speaker, the limiting factor for current is the
signal voltage divided by the voice coil dc resistance, any inductor dc resistance, plus
speaker wire resistance and amplifier output resistance. Of course, there is inductance
with all resistances I just mentioned, so the current will be lower still.

What makes a low wattage amp high current is a combination of amplifier supply voltage,
power supply capacitance, and current that the output devices are safely capable of passing.

It is pretty difficult to have a high power amplifier with a low current rating, but it depends upon
what you mean by "low current" rating. I know that sounds like a cop out, but there are so  many
variables to deal with. As the speaker impedance rises (say 16 ohms), the current requirement
lowers, yet with higher voltage amplifiers, high power can be obtained.

I hope this helps Don.

I am on the list and will be trying them with The Monoliths fully active speaker when I get them.

Comparison is to a pair of Parasound A23 amps on the planar drivers.

I am looking for people who would be interested in trying these amps and posting their findings.
