New preamp or other suggestions?


I'm really getting tired of the harsh sound of my system. At this point, I honestly would rather listen to music in my car than in my listening room. I've always chalked it up to a poor room layout (and that's not something that I can change), because this same system sounded UNBELIEVABLE in the dealer's showroom. For what it's worth, I've already treated the room with Echobusters panels, which helped quite a bit, but not enough to make the system sound really enjoyable.

Recently an audiophile friend suggested that a good tube pre might make the system more listenable. The current system is:

Source 1: CAL Icon MKII HDCD w/PowerBoss power supply
Source 2: Music Hall Fidelity CD-25 (stock)
Pre - Bryston BP-20 line stage (balanced to pwr amp)
Power - Bryston 4BST
Speakers - Thiel 3.6
Interconnect (pre to pwr, bal)-AQ Lapis or Nordost Red Dawn
Interconnect (CD to pre) - AQ Lapis, unbalanced
Spkr Cable - AQ Midnite X3

The system on the whole is currently lacking mid-bass (the terrible room strikes again) and has a harsh, in-your-face high end. Of the two sources, the CAL has a MUCH better bottom end, but is lacking detail and air at the top, and has a very "forward" presentation. The CD-25 has a much more detailed (and enjoyable) top and a wider soundstage, but light bass.

I listen mostly to pop, acoustic jazz and contemporary electric jazz.

My friend suggested picking up a used AR or CJ tube pre in place of the Bryston. Another friend suggested replacing the op-amps in the CD-25 with 627's to enhance its bottom end.

I'm a musician and not an audiophle, so I don't know if the advice I've received will fix the problem.... I'm also on a budget, but could swing $1-1.5K on a new/used pre if that would fix my problem.

Do any of you experts (and I mean that sincerely) have any ideas?

I have to agree with the above comments, you will most likely need to replace the Thiels. I have had numerous pairs of Thiels (1.5, 2.2, 2.3s) with basically the same results, they can sound very harsh. But if you love them you might want to give this a try. First replace your SS preamp with a tube preamp. This change helped quite a bit. Then get MIT cables, I think I used the MH-750. The combination of the tube preamp and the MITs got my 2.3 to sound pretty good. But ultamately for type of music I listen to (Jazz) I moved on to Virgos should sounds much better.
Okay, I'll take a stab here. I agree with most of what was said but you might consider as a cheap fix, new interconnects and/or speaker cable. I'm not sure Nordost or the silver Lapis is a good match with revealing speakers and your amp/preamp combo. I think Sean is on the right track with cables and just to add to his suggestions, you might pick up some Cardas Cross or especially Golden Cross and see if it doesn't make a difference. Buy here on A'gon and at the least you could resell them and get your money back. You didn't give your room dimensions but it sounds like the room may not be big enough for the bass output of the Thiels. Good Luck! Mike.
Two suggestions.

Thiel tend to be bright and from my point of view they fail to involve the listener. For the oposite scenario I suggest Sonus Faber italian speakers: Cremona (3-way) or Guarneri (2-way). Then a Supratek preamp. So life-like and natural.
How good is the current in your house? Next thing I would do is try very different cables.Thiels and Brystons both have a tendency to sound bright, and you got both of them. Your source components are weak too.I assume that you are not ready for a complete overhaul of the system.But if you do, I would get rid of everything you have, everything and assemble a totally new set-up.
You might try replacing the active preamp with a passive from Placette or Bent. It will clean-up your system. I've owned Thiels and they are demanding speaker. They need to be well fed to sound their best.
