Should I upgrade my preamp?


There are no decent Audio stores close to my home anymore. I used to travel 50 miles to Paragon Sound in Toledo, Ohio. I could select a piece of equipment new (floor model) or used and bring it home to plug into my system and try it before I’d buy.  So, my question the group is, I’m thinking of up grading my preamp. I have always felt the preamp was the heart and soul of a system and the greatest change would come from changing the preamp. I’ve been watching used ARC preamps on eBay.  Would an ARC LS28 be to much of a stretch for my current system?  In the past I’ve enjoyed swapping out the single 6922 tube in the preamp and the change was always noticeable.  Currently I’m running a Dutch Amperex 7308 and my favorite so far. From top to bottom a very musical tube. What are your thoughts? 

 

Current system:

Denon DSD 1500 CD player

Audio Research LS2B MkII

Audio Research  PH3SE

Aragon 8008BB

 

Vpi Aries gen1 turntable

Vpi Line Conditioner

Graham 2.2 tonearm

Benz Micro Ruby ZH

 

Thiel 3.6 speakers

128x128dgb553

I am not of the camp that you must understand what is missing from your current system. When you perform a significant upgrade with high quality components, you find out what you were missing. When you are talking about components like ARC you can be certain of great results. The upgrade to an LS28 would be a great upgrade. I completely agree that the preamp is the heart snd soul and this is a great preamp. In addition it sets you up to hear marked improvements when you choose to upgrade any other of your components.

 

I have owned many versions of ARC preamps and phono stages. They are wonderful. They only stumbled a bit on the REF 1 and REF 2 preamps.

I have owned many ARC preamps including the LS2B, but not the MK2. I also feel the preamp is the heart of the system. Much more important than the amp. I currently own a Ref 5se which I dearly love. My Ref 5se was a demo. Buying a demo or even used can save quite a bit of money. And it is already broken in. The LS28 is a wonderful preamp and would be a significant upgrade. Get the se version if at all possible. Speakers would also make a big difference. 

 

My advice is to make a long term plan and work toward it. Upgrade one piece at a time. Maybe a preamp first and then speakers. You may not realize the full potential  of the new preamp at first. But as you upgrade other pieces you will. And you will not feel the need to upgrade it for a long time.

 

tomic601 Yes, I’ve been checking with Ann Arbor for several months now.

mrdecibel you are correct, it is DCD-1500, typo on my part. If I remember correctly, I bought this player in 1986. I’ve tried other CD players over the years and they either lacked in bass or the highs were to bright or tinny sounding and in some cases less detail. My system’s sound stage is not mid-hall depth, it’s more like the 10th row and very engaging. The preamp is 30 years old and to my ears it has lost some of its magic. So, is time to replace or recap or maybe look for a new CD/SACD player?

I forgot to mention speaker cables and interconnects are all Transparent Music Link Supers.

We moved a few years ago and my listening area is not good, my sound stage is very compressed now. 

Soix I grew up listening to tubes. When I was little, I remember watching my father build his first stereo preamp from a Dynaco kit. So, with ARC’s newer equipment moving away from the house sound that embraced tubes to something more neutral, with just a hint of tube sound. I hear your warning and it is my primary concern.

@ghdprentice ,1st, I would like to say I read the majority of your posts and enjoy your sentiment and opinions. However, you and I are very different listeners...and this is ok. I spent most of my life helping others build / upgrade their systems. You say you do not believe you must understand what your system is missing. Maybe the word understand is not the correct word. My experience shows the listener simply wants more out of their system, before the upgrade comes. This is the reason for the upgrade in the 1st place. To take a system, and simply exchange a new component for the sake of it, is not how I see it. A listener needs to know what his / her priorities are, with music and sound, in building a system, and I tried to help / teach this to the client. The 1st and foremost step in helping someone with their system build / upgrade, is to determine what sound / presentation do they want, to learn what their listening habits are, the music listened to, and of course, the environment they are in. I know you love AR tube gear, and SF speakers, and I understand why. This presentation might be fine for you, but not everyone. Admittedly, not my cup of tea, as I believe you might feel the same concerning my system. Why, because we both value certain aspects of recorded music reproduction. So, what is good for you, or me, is likely different than the next person. Most listeners I correspond with, are still so lost in achieving their holy grail. They have not figured out what they want...or know what is potentially available. A problem that exists ime, is that listeners do not know the difference between the reproduction of recorded music and live, unamplified music, and try to achieve that balance of both. I apologize for going on and on, but recommending anything to a listener who wants to upgrade, I need this information to help them further. Before I retired, I did have many happy clients, because I concentrated on what "their" likes, wants and desires were, and helped them get to that point by educating them to the best of my ability. Anyway, I hope this did not turn you sour in any way. Remember, ymmv, we are all different, and music listening should be fun. Listeners, mostly audiophiles, experience neurosis with this hobby, which is why I retired. Unfortunately, it is getting worse, imo, likely because of the world we live in. To the OP, good luck. Again, I apologize. My best, MrD.

 

@mrdecibel 

My experience with high end audio has been that each significant upgrade I have made of high end main stream audio components has resulted in a great improvement on my system. I agree that it is very helpful to know what sonic characteristics you value. But, you need an experience base to really understand what the choices are. In the case of a preamp and what we know about the poster, I think the ARC is a very safe bet for this person. Now if it was speakers or an amp, much more information would be required. 
 

I agree that we have different values… and that is fine.
