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!!

Hi Gunbei: The D60 should certainly liven things up a bit (probably a good thing that you held on to it). All of my digital equipment also sounds a bit muted (less detail) when it comes up from a cold start and offers more detail in approx. 3 days (though it does sound better in just 24 hours). I just mentioned, because of this, in the "CA Power" thread, that I always keep the digital stuff powered up (even when changing IC's - I am just very careful when doing so). Perhaps by Thursday or Friday (keep it powered up 7/24) you will be experiencing more detail. Another odd thing about equipment that has recently been shipped is that it seems to arrive with some type of charge to it (maybe static). This is very noticeable to me on recently acquired tubes (which attract dust like a magnet for a few days and then it wears off). Maybe this charge is generated by all of the machinery, sorting belts and scanners involved in transportation (I really don't know) but it is a real phenomena as when I clean the outside of the tubes with anti static wipes (that I also use on my eye glasses) it cuts the startup noise (created by the charge?) almost in half.
Greg: Any tips on how to get rid of the static quickly (other than submerging the gear in water:-). The sound from the tubes drives me nuts, when I start up the amp for that day and a half or so and I always wonder if it is harming the tweeters.
Whatjd: If the cable is not a part of the "stereo", can this still make a difference? I assume that our electrical panels are connected to a different earth ground than the cable (which is a cold water pipe as you mentioned), but will double check. The "cable" just runs from the outside box to the TV's (we don't even have the boxes as we have the basic service).
Gunbei: Excellent. Sounds like it was just a not so good connection or maybe static. I think that I remember the gun(s) that Greg mentions (seems to me that they had a piece of quartz in them or something like that). I will ask a few oldsters I know if they have one that I can try out.
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.
Hi Jim: It just dawned on me that the outlet that I am using at this time tests as having an open ground (which is none at all I think). We have another line going to the living room that also is not properly grounded. I have not gotten around to checking all of the outlets yet to see if it is just a loose connection (down the line including the breaker box) or if there is an actual break in the line itself (in this case a new one will have to pulled from the electrical panel). The last electrician that we had over (hired by the landlord) did not fix diddly (as my testing of his work with a RS line tester showed). One of the outlets that he installed was just hooked up wrong and did have a ground when I wired it correctly. We do need a "good" electrician as the wires are either all white or are the wrong color for what they are supposed to be and I will heed your advise as far as pro help goes (I have one outlet with 5 leads, two red and three white, for crying out loud).
