Business Changes

Marihart Audio will be changing from high end audio sales to doing strictly acoustics for the home and business.  Due to weak sales and me just getting tired of trying to compete in a very small market I am calling it quits.  We have already purchased a fair amount of gear for the acoustics business and will be getting some more in for our roving demo.  So as of this moment, the majority of our new and used gear is going on US Audio Mart for sale.  I am also closing down the shopping cart over the next few days so that it and its tabs will disappear from this website.  I will maintain a presence here on the website, and will email my old and new customers of the gear going up for sale before it goes on US Audio Mart.  Thank you everyone who supported the Audio business for the last 8 years-and yes I really am calling it quits this time.

Sierra Nevada Audiophile Society Meeting April 12

SNAS will be having its monthly meeting on Saturday, April 12th, at 1 PM at Derek Hughes’ home. Please call 530-320-1576  for directions or the meeting email info.  We will be launching the new SNAS website, with Dave Dodds giving us a preview and the how to on the website.  It is very interactive and has public and private sections so we can load reviews in the public domain and post our pics and favorite albums, etc. in the private section.  It will be able to do a lot that the old site had no clue of.
Also we will have a Margules system featuring Acoustic Zen Adagio Jr. speakers and wiring for your listening pleasure.  A totally different sound than the previous system with the Brodmann’s.
Hope to see you there!!!

Marihart Audio, PMI Engineering and MSR Acoustics

We are proud to announce that Marihart Audio has become dealers for MSR Acoustics line of products, and has PMI for your more involved acoustical engineering problems.  MSR has a complete lineup of pre-engineered products for your audiophile and home theater needs.  These are engineered for specific range of standard room sizes and are reasonably priced so you can get the most out of your system.  As a dealer I can give recommendations and help choosing the right set for you.
For your more complex room arrangements and home theaters PMI offers engineering solutions and in home consultation to find solutions for your problems and needs.  Literally anything is possible-do you want a home theater that doesn’t look like one-no issue.  Do you want complete room isolation from the rest of the home-no problem.  Both? Again no issue.  Marihart Audio will do the initial meeting and take measurements and pictures.  Later Tony Grimani (one of the top engineers in the USA) or one of his engineers will meet with you to nail down details and finish engineering.  PMI has a host of superb contractors they use for acoustical installation and finish work.  Marihart Audio has a set of pictures I can send you demonstrating these concepts and the quality of the workmanship.
We also help the homeowner with acoustical issues caused by hard surfaces-tile floors, lots of windows, and combinations thereof.  There are solutions out there that help tame excess reverberation in the home that are unobtrusive and very effective.  How we can help can be determined by a free in home appointment  by Marihart Audio.
We look forward to this new phase of our business, and helping people find solutions to their in home issues.
For more info please check out: for acoustical treatments and for the engineering, design, and execution.

Guide to Cable Selection

I am writing this because there is a lot of confusion about cabling and how to put it together.  When you want to upgrade your cabling please do not go the route of replacing one cable at a time.  This puts you into a serious issue of trying to get dissimilar cables and cable companies to play well together.  I have tried this for years with little satisfaction.  And I am not alone in this discovery.  Please get a complete loom (speaker cables, interconnects for all components, and even power cables) from a dealer and try that.  You will get a much better picture of how that brand sounds in your system.  And you may be in for a big surprise in that the lower cost stuff may sound better than using that one really expensive speaker cable or interconnect with your old stuff.  I believe that the reason for this is that the capacitance and inductance of a set of cables from the same manufacturer are very similar, and that all manufacturer’s cabling varies widely on this issue.  The amplifier, preamp, and source equipment are much happier looking at similar capacitance and inductance than widely varying ones (as would happen with different manufacturers).  A good dealer should know what pairings work best within a manufactuer’s products and can make recommendations to fit your budget.  If he doesn’t know-get another dealer-that’s his job.

What is the Sound of No Phase Shift? Notes on the Exemplar eXception

Nov 16, 2013
One problem all designers of high end gear face is that all (with few exceptions) capacitors induce some degree of phase shift in the signal.  This is a major issue when caps are almost always used in the output stages of amplifiers.  This issue has been almost never addressed to my knowledge in the industry (one of its dirty little secrets?).  They have addressed how much latent energy is held by a cap ( see C1 capacitor upgrades-Conrad Johnson), but little on phase shift.  This recently came to my attention through John Tucker of Exemplar because of capacitor phase shift research done in Japan.  The end result was that all poly and teflon caps phase shifted except for one commercial cap made in France.
Enter the Exemplar eXception integrated amp.  A new design by John Tucker-it utilizes these caps and other proprietary technology developed here by John and in Japan to give one phase shift free sound.  I have been listening to it in my system for the last 3 hours-running through its paces-after giving it an all day warm up.  I have never heard an amp that is as neutral, non-existent as this amp.  There is only music-nothing else.  Dynamic, warm, fluid, black background, timbre accurate, doesn’t begin to describe what I hear.  On Copland’s Fanfare for the Common Man (Telarc) the cymbals are fluid yet one can clearly hear the shimmer and metal in the instrument, the brass sounds exactly like brass, the kettles’ skin and wood resonate clearly, all with lots of air and depth.  On Patricia Barber’s What a Shame (Café Blue) she is in the room, the wood in the stand-up bass giving the instrument shape and depth, the guitar’s attack forming in the air in front of me. And on and on.  Perhaps my heavily modified Cary SLI-80 may give it a run-but there is a speed that the eXception has that I know the Cary can’t quite match.
On to Info on this Amp:   50 W/ch both channels driven at 8 ohms, high current solid state outputs with tube preamp, remote, silver aluminum face with 6 inputs, can be custom modified on inputs, comes with mute, and cinema bypass.  Retail is $4950.
Nov 20,2013
Dave Sykes and I auditioned the eXception against a reference system using the Pass Labs XP-30 preamp, XA-100.5 monoblocks, and XP-15 Phonostage, with an Exemplar Audio 93 for CD’s.  Wiring was Zu Audio’s best, and speakers were the Zu Definition Mark IV.  We listened to the Pass gear first, letting the eXception warm up, then put on the eXception.  The results were quite surprising as we both felt that the Exemplar piece quite held its own against the Pass gear.  On some cuts the bass was actually tighter than the Pass, highs were just as defined most of the time, occasionally there was a slight edge on the high brass and violin notes-but still well defined.  Timbre accuracy and harmonics were generally exceptional-not indicative of an integrated costing 1/6 as much as the reference system.  Both had superb depth and air, with a huge soundstage.  Remember, the eXception we had here was a beta test unit, not the production model which has higher resolution and a faster power supply.
As a result, I ordered the eXception and should have it in a couple of weeks.  It is by far a giant slayer-if you want world class sound at a budget price-this is it.  I do recommend using it only on speakers with 90db sensitivity or better.
