Thanks for the review. Just curious, did you have to float the ground or are you using a 3 prong power cord? Did you upgrade the power cord and have you tried any tube rolling?
Review: TAD (TubeAudioDesign) TAD 150 Signature Tube preamp
Category: Preamps
Just wanted to add my review along with the other excellent review previously posted here, about the TAD 150 Preamp, as my system is different, in many respects, so it will hopefully offer a different prespective.
I had always been a staunch "NO PREAMP" audio guy for a loooong time. This is the first preamp that I have owned in over 10 yrs.
I just believed that the best preamp is NO preamp, so have always designed my system around either passive preamps (Reference Line 2b, which I still own) and by utilizing CD players with "direct out" capabilities. Past CD's of this type have been Mark Levinson No. 39, and Theta Miles, in that order, prior to my A.A.
Well, long story short, another audiophile friend of mine suggested that in many cases a good preamp can actually improve(?) some areas (micro, macro dynamics, midrange timbre, etc.) that you just can't get without using one, despite agreeing that going "direct" will probably yield the most "transparent" reproduction, so I thought, what the hey, I'll give one a try.
Being enamored towards tubes, ESPECIALLY, in any "front end" component, I started a small search around to see what was considered a good value, in tube preamps. I came across Paul G.'s TAD preamp after a recommendation, and after reading the many very positive reviews posted here and at other audio related sites. The design looked great and seemed to offer a lot of bang for the buck, as it were, so....
Let me first say that I was VERY skeptical that this preamp would actually "improve" the sound over my much beloved Capitole, so if anything, I went into this with slightly negative expectations.
Well, you know what I'm going to state here -- yes, after letting the preamp thoroughly break in with my XLO/Cheski burn-in disc, for about 100 hrs., I was ready for serious listening, and WOW!
First thing I heard was a very noticable improvement in the bass. This was completely unexpected, and I hadn't realized that the bass coming direct from my A.A. was a bit muddy & loose, compared to the now cleaner and tighter (but just as deep and authoritive) bass now reproduced via the 150 Sig.
Next was in the realm of dynamics, on both ends of the scale, micro and macro. This wasn't as big of an improvement as the bass, but was still noticable in a better "jump" factor on dynamic recordings, and more natural dynamic shadings, overall, in all recordings. All this without ANY increase in the background noise level -- still silent and "black" as ever.
The soundstage and stage depth were surely areas that would suffer, right? Nope. This is one of the great strengths of the Capitole, as it throws a HUGE, expansive stage, with tons of air and depth. No improvements, per se here, but I really was just hoping no loss would be incurred with the insertion of the TAD150, and this proved to be the case. No change. This was true when using both the excellent TAD1000 mono block amps and also with a Bel Canto EVO 200.2 that I had on hand.
So, what do we have? Better bass reproduction, better dynamic shadings, no losses anywhere else. Yep, this over- achieving preamp's a "keeper" in my system!
I must point out that I am by no means an expert when it comes to preamps, as again, i just haven't tried that many over the years, but I did have on hand a Counterpoint 1000? all tube design, which I borrowed from a good friend (and who's system I always felt was very musical), to compare to the TAD150. We both agreed (much to his dismay) that the TAD150 trounced the Counterpoint in all areas.
Quick, short list of other preamps I have owned over the years; Conrad Johnson PV11, Perreaux SM3, Carver ??, Reference Line 2b passive (still own & will use in vinyl playback system)
Bottom line ; anyone in the market for a great tube (or SS) preamp should look and listen to this preamp before spending any more or looking at anything used around this price point.
Very highly recommended! Kudos to Paul Grzybek!
