Panasonic SA-XR70S - On It's Way To Colorado

I do offer a power cable based on a twisted pair of 14 AWG NIRTO wire with Teflon insulation. It is designed just for the Panasoinc. It uses WattGate connectors and is only $70.00 for 6 feet.

That is what I would go for myself, hard to top that for that amount of $$ even if you DIY. The Nitro power cords are very good, IMO.

Good lord, I guess Wayne gets 1000 dollars from me this Christmas season, buy your wife/girlfriend/whatever something really nice

Thanks Daryan,

It will probably all go for hockey gear. My 16 (will be 17 next month

) yr. old son plays in a Midget level travel team for DU. So far this season, I have had to shell out for new breezers, helmet, 2 uniform jerseys, track suit, socks, TWO sticks and four blades. He has four games and two tournaments coming up in the next four weeks.

He is going to start playing inline hockey for his High School in January.

Youth hockey certainly has a way of making one's wallet very thin, very quickly.

I heard from Wayne recently. My pimped out SA-XR70 should be finished soon and will hopefully ship back to me next week.

I also added a Nitro Power Cord with Furutech Rhodium connectors to the mix.

My fingers are crossed as to the sound quality.

I wouldn't have to many worries. After reading some of the reviews on his work from some dude named Tyson on this site, it sounds like a real winner. My xr-45 is there now! And to add to this, if the work is half as good as the customer service, it will sound outstanding!

I have a tracking number from Wayne.

Its on the way back from Colorado to NJ.

Got my XR70 back from Wayne in good shape.

Have it hooked up breaking in playing FM music now. Also got a Nitro PC with Furutech connectors.

Wayne did a really nice job on the mod package.

Will report more after it breaks in for a few weeks.

Thanks Wayne

Got the XR70 hooked up to the digital out of my computer EGO WaveTerminal 2496 soundcard.

Sounds great. Dead silent no noise. Played mp3 & cd's.

Really sounding good with all digital connection.

This modded Panny XR70 is really nice.

XR70 has been running in for several weeks now. Sound quality has been up & down a bit. Recently has really smoothed out.

I picked up a used BPT 2 from AudioGon and connected it up yesterday. Improvement was incredible. Sound became holographic.

This is a great sounding system.

Steven,

I am glad the Panny has finally broken in most of the way. The new caps, wiring and connectors do take some time.

Power conditiong is VERY important to any audio product that uses a switching power supply.

That is why I picked up the Equi=Tech line. I do feel it does a better job for digital gear than the BPT.

With the Equi=Tech, you could plug your source (your computer I believe) into the second set of filtered outlets and isolate the two switching supplies from each other and anything else in your system.

Prices start at $750.00 for the SON of Q Jr. I do offer a very good discount off that for AC members. Please contact me by PM for pricing.

How so?

All of the outlets of a BPT Transformer are tied together. There is no isolation of one outlet from another. Anything plugged into the BPT that uses a switching power supply will polute everthing else that is plugged into it.

The Equi=tech uses filters that isolate two separate duplex outlets from the other outlets. So you can have two different switching power supplies plugged into it and they will not have any effect upon each other or anything plugged into the other outlets.

Hi Wayne - thanks for the response!

I haven't finished going through the Equi=tech website yet, but BPT lists "Separate noise filters on each duplex outlet to reduce component interaction" on their website.

I would presume that in both the BPT and Equi=tech units, the "filter" means the addition of a capacitor to each duplex, correct? Is there another (better) means of this filtering, short of completely separate toroids for each duplex?

Thanks again!

I am afraid the capacitors on the BPT do pretty much nothing for isolation. If you look over in the LAB, Occam does a very good job of explaining how a capacitor across the INPUT, filters out high frequencies but does NOT isolate components.

DIY Power conditioner

In fact, the capacitors across each outlet are superflous. As all the outlets are connected together, one capacitor would work for all the outlets. Having one across each outlet just changes the value of capacitance.

The Equi=tech power conditioners have two separate filter networks consisting of inductive, capacitive and resistive elements to isolate any load plugged into them.

In the picture above you can see the filter networks as the two silver blocks on the left hand side.

Ok, I finally got through that long, but informative thread... thanks for the pointer!

Ok, so I'm sensing another one of those trade-offs that every designer has to make... namely the inductive part of the isolation network. From what I've read, inductors can limit dynamics of high current draw components, namely amps. So you are potentially trading this for greater isolation between duplexes, correct? Is there something else that alters or eliminates the tradeoff?

Thanks again for the education, Wayne! (And Paul and Josh via the previously mentioned thread)

A lot depends on what amps you are using and how bad your power is.

None of the digital amps are high current draw. The benefit of the isolation far outweighs any minor current limitation. In mgalusha's case, his circuit for his streeo is on the same feed his office computers are on. They create quite a bit on noise on the line. His system sounds best with his Odessey Mono-blocks plugged into the conditioner.

The BPT has an inductive filter before the transformer. So EVERYTHING going through it will be limited. The Equi=Tech has two after the transformer just to isolate digital compaonents.It has three circuits with no additional filter for high current draw items.
