Confused By A Transport Upgrade


Dear Forum Members:

I just got a used Theta Pearl CD transport on monday. The change in sound from my previous transport[CD player actually] is so dramatic, I don't know what to make of it. In the course of trying to building a nice musical system I've experimented with different speaker cables and interconnects and isolation tweaks, but nothing has made such a dramatic change as adding this transport.

My system is comprised of Sim Audio Moon I-5 integrated, Musical Fidelity E60 CD player, Bel Canto DAC 1.1, Sonus Faber Concertinos and ProAc Tablette Signature 50s. I have added these pieces incrementally starting with the MF E60 three years ago, then the Concertinos a year and a half ago. The Moon I-5 arrived last August. I just received the Bel Canto and the ProAcs last month.

Since the beginning my system has always been on the bright side. In order to combat this characteristic I have experimented with different interconnects and digital cables eventually settling on the relaxing Cardas Golden Cross and L-15. I also upgraded DH Labs Silversonic T14 speaker cables to Analysis Plus Oval Nines. These changes have helped somewhat, but still the occasional nasties remained.

The Theta Pearl is a solid piece of gear using the Pioneer stabile platter mechanism with the CDs inserted label side down. Before hooking it up, I played 3 CDs I'm pretty familiar with through the MF just so I could have a fresh taste of the 'ol transport before getting down to business with my new toy. When I started playing the first CD in the Theta I was shocked at the Jekyll and Hyde difference between the two players. In comparison to my MF E60, the Theta is leagues softer, and fuller in the midrange, almost to the point of sounding muffled. CD after CD I kept thinking to myself that I had lost a ton of detail and information.

Now here's my question. Have I become so accustomed to a thin sounding, overly bright, and falsely detailed system so much so, that a well regarded transport such as the Theta Pearl sounds, dare I say wrong to me? I've been searching for a non-fatiguing system for so long, and now that I have it, I yearn for the lifelike energy that some of my CDs exhibited when played through my $500 MF. While it was often thin and bright sounding, it sometimes created spookily real instrumentation and voices.

I'm now contemplating a reverse change in my interconnects, speaker and digital cables. I have a run of Kimber Illuminations D60, so I'll see what that does. Will it restore some life in my system? Maybe all the Cardas are wrong in this setup. Should I change the AP Oval 9s to Silver Ovals?

What have I done wrong? Help!!

Zerostat 59.95 at Audio Advisor. Don't tweak a system without one (unless you live in a way humid climate)

Thanks for the product name Pls1. I will try to find it elsewhere though as I have decided not to do business with AA in the future.
Whatjd, Interesting comment. I just moved and after the satelite was installed I noticed the system didn't sound quite as good. I kind of chalked it up to " it's a new room, just getting used to it" I also noticed the other day while mowing the lawn that the ground wire for the satelite is tied into the house ground. How can I isolate this? The system runs on 2 dedicated lines, but the ground is common.I definately have to put a meter on it to see if it has d.c. Thanks in advance for any help you can offer.
For anyone that read my comments...do proceed with caution.
Star grounding, and other thoughts that have been mentioned
on grounding, are all trying to take care of system ground
noise(or worse), or trying to get rid of ground loop
problems. The concern, however, is to not cause a different
ground potential between components that could result in
a shock potential. So, what to do? Even though I have
a background in consumer electronics..and electrical repair
in the Air Force...I cannot, via internet long distance,
make sure that anything anyone does is safe. My problem
in my system was that the cable feed was grounded to my
electrical conduit comming into my house..and that my cable,
like many, had quite a bit of DC voltage on it. I removed
their grounding strap...ran a real earth ground for the
cable input..and installed the Mondial Magic behind my
TV for good measure..and my Stereo(there's an old term)
sounds much, much better for it. For David and all above,
do proceed with caution and/or get some advice/help from
someone that understands....ie: find an electrician that's
into the high-end...if you can. The only advice that I
think is proper....deal with getting ground concerns taken
care of before they are attached to your electical feed..not
after...ie: get that cable feed or satelite feed earth
grounded to bleed off any DC or other noise before it is
introduced to your electrical system...rather than the
"cableguy" just attatching it to your electrical..all that
is doing is making sure there is a common ground..and no
difference of potential..ie: shock concern..but it is not
addressing if or if not the cable or satelite has anything
on it's ground that should not be there/or bleed off before
the feed is introduced to your system in the first place...
But...and that's a BIG BUTT...I cannot over state how many
of you out there have systems that sound a GREAT deal poorer
than they should because of ground noise/DC voltages on the
circuits you have your system connected to.
I would second Whatjd's comments and add to them. I have a Digital Music Express satellite set up to receive their 110 channels of music. In addition to the grounding issues, I have the receiver on a seperate AC line with heavy AC filtering. However, what was necessary to keep the pile of RF and other electrical grunge out of my system was converting the coax digital out to ATT optical with a Theta Linque. This stops any electrical grunge from getting into my main system. It makes a big difference.
