Shall I add a preamp to my setup?


I newly setup a system with Thiel CS 3.7 speaker, driving my Sim audio Titan 5 channel poweramp, source with Simaudio cd5.3, I am very excited with the 2 channel performance, but it seems lack of warmth of vocal and extension of high, not enough airly extensions, base is fine. I doubt my weakest link is the Sherbourn PT-7010A pre/pro, all the above new gear has pretty much break my bank, I wonder if I should squeeze the rest of bank reserve for a descent 2 channel preamp in order to solve the problem.....the other choice is a better CDP, can someone walked thru the similar path give me some advice?

Conrad Johnson Met1 6 channel hybrid tube preamp added warmth and imaging to my denon ht setup. Might be just the thing to compliment the Titan.

Tube pre with pass through, huh?

That shouldn’t be too difficult a thing to come by these days as many makers are putting that into their designs for the HT systems everyone is doing now.

Personally, I feel the two, stereo and HT should remain separate things for consistency’s sake… I’ve been unable to make a pair of tube mono blocks sound like solid state nor do I care too… then with some pass through preamps, they need to be on, and there’s that added pair of interconnects too. In any case, it should be a simple task to find one I suspect.

I have a Thor preamp… they ain’t being made now. The designer took a powder on us… but they are a stellar item sonically speaking. Some of them were made with pass throughs for HT.

Mark Mickelson had one for a time too…. Then went to a VTL 7.5. In his review of the VTL 7.5 he compared it to the Thor saying it was no better sonically but offered more versatility. I would think the VTL 6.5, would offer a great deal of the 7.5s performance for far less… but that’s sheer speculation.

I would also think the aspect to look for in a tube preamp is it’s inclination to the musicality aspect, over the speed and resolution facet… which is what I suspect you seek. I wasn’t terrigbly impressed by the new CJ preamps I heard. They sounded far more akin to solid state than to tube designs. I hear some of the older CJ pres were far more about the warmth and midrange though.

I’m really at a loss to add much here for you to investigate in this regard. I will say, having owned a BAT VK 5i, that either it or the VK5i SE should certainly do what you want and are well within your price range with lots left over… if you don’t mind buying older gear.

Perhaps VAC should also be on your short list, and maybe even Quadd… with $6K in hand for a preamp I’d still look at the VTL stuff, then VAC… and probably ART Audio & ARC… but that’s just me.
I am new at Tube amp, how long do I need to change the tubes, how will I know if its done? Any other advice on handling a tube will be appreciated.
BTW, is it dangerous to buy a tube preamp used? Particularly not knowing the remaining life of the expensive tubes.
Buying anything used isn't entirely dangerous regardless the the item. It does have it's ups & downs though. Using some prudent judgement, and doing some howmework/research on the seller and the intended item is a must however.

I bought what I thought was a 3 year old BAT VK 5i from a seller who I believe is no longer a member here. it turned out it was closer to ten years old in fact. The misrepresentation of it's age was of course, an issue. Once new tubes were installed in it though, I was very pleased with it's performance overall and held onto it for a couple of years until the upgrade bug bit me... and then I bought my Thor and sold the BAT.

Tubes in general last a pretty long time. Some say thousands of hours! 3000 and up isn't unheard of, some tubes life expectancy go upwards of 10,000, 'New' or NOS of course.

Used tubes can do pretty well too. it's all about what you want to do and can afford I guess. Getting some used tubes is an easy and cheaper way to find out what suits you too. here, again, the seller's reputation is most important. There are several here and off Audiogone which are most competent and trustworthy.

Age of the component is a factor too, though if the maker is still in business it is less an issue than if no original support is available, natuarlly.

My own preffs tell me to not buy vintage & antique gear, but some swear by it. Again, this is a matter more of preffs than actual betterment and remains quite subjective, IMO. I've lost the ability to properly serivice electronics so for myself, support is key.

I also limit myself to buying electronics that are but shortly used, if at all possible... 2-3yrs. max., and less if possible. The build quality of anything is gonna reflect in it's longevity and performance too. Again, by the time I sold my BAT preamp it was over ten years old and played flawlessly and sounded great!

Keeping in mind your situation, preffs, experience and so forth, it may be best to buy something inexpensive right off to see what is what in the tube world. Something with some popularity too, so reselling it if not to your liking won't be a big deal. Any of those companies I've listed above are worth investigating and you'll not go far wrong... if at all.

Sticking with a preamp whose tube array is current or plentiful is also a good idea. Like the 12AT, 12AX, 12AU, 6DJ8, 6922, 7308, 6sn7, etc. and they all have their own sonic signatures... which is good for you can buy & try out the same 6922 from any number of makers and customize the sound to your preffs.

Lastly more tubes inside the unit doesn't mean better all the time... it does mean more money to outfit it all the time though... but that'll only happen due to whims or every 4 or 5 years, depending on how much you play the thing. 4hr. per day = <1500 hours per year.
