Tenor Hybrid v. VTL MB-450 Sig.


I am planning on replacing my VTLs with the Tenor stereo 150 hybrid . Since I will not be able to hear them first and since they are a substantial outlay over what my VTLs are worth, I am hoping that some of you may have heard both. Would you mind characterizing the differences that I should expect to hear? I have Merlin VSMMs, a First Sound preamp, and an Audio Logic 24mxl DAC. Other amps that I am considering are the Joule VZN-100s, or a CAT JL2. My pre-purchase buyers remorse is that they will be better but maybe not commensurate with the extra cost. I am aware of the higher cost/diminshing returns reality. However, from what I have read, these hybrids seem to be a huge step up. If I audition a piece and hear an improvement that meets my personal cost/benefit ratio, I buy it. So, with no personal experience with the Tenors, I am finding it is a bit difficult to make the leap to buy the most exp. piece of gear in my system. Any input you may have is greatly appreciated. By the way, JTinn and I have had several conversations about this subject. He had been very helpful and generous with his time. In this post, I am looking for more of a comsumer point of view.

This thread is amazing I love it!!

We have manufacturer's posting: 3+/-
TG audio/CTC engineering,
Merlin(btw Bobby we met a few years ago at Mario's place in White Plains- I still liked how that room sounded with the prototype JL2- that was my first experience with your speakers) and
Shunyata!

We have Brian the super cool guy from Essential Audio. I have never seen this much interest in a thread from so many people in the business.

On topic I am a Tenor fan, I feel they are possibly the finest amplifiers available, but clearly they are not for everybody for obvious reasons(price comes to mind). VTL's are great amplifier's as well, but not in the same league of performance as the Tenor's. There are a few questions you need to ask yourself before you jump in any one direction, how much are you willing to spend? It seems like it would be worth while to get your speaker upgraded if that is an option from Merlin. I spent a long day of listening with Bobby at Toys from the Attic a few years ago and was really impressed with what his speaker's are capable of- the tweaks and adjustments he made to the system all day were amazing(after 8 hours it sounded like a completely different system). I can understand why you like them and feel that it would be worth looking into upgrading them. If your still not satisfied and want to continue on down the upgrade path I would urge you to arrange an audition on the Tenor 150s hybrid dual mono amplifier. I have listened to the original 75watt otl's and the 300 hybrid mono's and what they do NO other amplifier can do better- transparency and resolution must be heard to be believed. If you are happy with your speakers and are looking for that last bit of performance the Tenor's would be the way to go- IMO and they would be able to power your speakers with aplomb(though I don't think that is a high priority for you). In any case the advice given to you on 1-16-04 from Grant at shunyata(aka Samuel) was the best advice I have heard in a long time- don't put a lot of stock in what any one says here, including me. Good luck with your voyage and please keep us up to date with what you decide.
Tubegroover, I didn't mean to sound condescending toward Jim2 nor to anyone else and apologize if I did. Truth be told, and Bobby knows it, I enjoy visiting his room at CES each year to play some tasty vinyl cuts...always fun... Some of my customers have Merlins, and they are treated with the utmost respect just as everyone else is...

I'm sure they are Brian, I was just surprised as it was coming from you who I hold in high regard in both your demeanor and taste. I just feel that Jim has received enough flack from everyone else, the point was well made prior to your post. Along with being a passionate Merlin owner he is also one hell of a great guy. Typed words without personal contact have a way of muddling things up a bit.
I think sometimes my words can have a little more bite to them than I intend. I am not much for BS and I try to call it as I see it. I think I remember being told I was wrong once. I don't recall exactly as I disregarded the comments.

I think this thread/string is a good example for people considering various components/opinions via the internet. Even those with a tremendous amount of experience in the hobby can offer opinions that don't entirely reflect what is so. That goes for experienced owners as well - me included. I must say that I have gotten pretty lucky with respect to equipment selection and what makes me happy. If there is any advice I can offer about selecting gear, or in this case - an amp, it's to try and spot trends of opinion from people you can discern have experience and similar tastes as yours. Would I ask Crump to recommend an amp for my use? Probably not. But he might be an ideal resource for someone else. And we're fortunate enough to have his experienced opinion. There are a few people whos opinion I consider a stone cold lock as it relates to my own perferences and tastes. And it is helpful to consider their opinions when wading through the chaff. That's my little nugget of pseudo-wisdom for the day.

Kevinkwann, you ask an interesting question. It reminds me of a conversation I had with Bobby around the time I heard about that 6th toe mod. As I recall, it was not based on rocket science but rather, "I wonder what would happen if we tried this today..." I suspect that sort of engineering accounts for much of the best gear in the industry today. I suppose it's the sort of thing that people with a passion for their product do. Whether or not it's commonplace for floorstanding speakers to have extra thick baffles the entire running length of the front, I am not certain. I don't build speakers or pretend to. I just know what I like. In any case, I am obliged to warn you of throngs of Merlin fanatics headed your way armed with slingshots and tubes. :)
Hi Kevin,
I ask you to read my last post again as it explains that the resonance issue was actually dealt with prior to the review in Stereophile. Flying changes to the production of the VSM were made in advance of the review but the review sample did not have the changes because of the time issue. The truth of the matter is that the resonance is not measurable unless extreme output (well above 100 dB) is generated making this a non issue for 99.9% of the listeners. That is why this matter was dealt with after the cabinet material change and not before.
Regards,
Bobby@merlin
Bye the way Kevin, did you ever do the sixth toe mod to your speakers? This will make a really big difference for you and actually further reduce energy build up in the VSM while providing more stable footing. The additional bass extension and fullness makes a really big difference to the ambient energy and size of the presentation. The ERS and tuning puck makes the sound more uniform so you can really hear into the music core to a greater degree. Additive noise in the way of RFI and EMI can add a false fizzle to the sound and once this is removed, the resolution, smoothness and purity are enhanced.

Bobby@merlin
I just re-read your post, Bobby.

D'OH!

I will endeavor to improve my reading skills.
In any case, fwiw, I think your VSM speakers
are among the most transparent and dynamic on
box speakers on earth. Those who "think"
the Sound Labs can achieve anywhere near the
dynamic nuance and capability are kidding themselves.
Or just don't know better.
Hi Bobby. I'm not a Merlin owner. I'm merely a Merlin admirer. I'm always amazed when I hear good things about speakers that cost far more, Rockports being a good example, but that don't have nearly the capability. The Rockports I've heard (Hyperion, Antares), for example, swallow dynamic nuance and suppress the dynamic and leading edge excitement inherent in live music. Merlin gets these aspects of reproduced music right.
Kevin, it's interesting you mention that about the Sound Labs. I came across a local guy that has a pair of Sound Lab M1 speakers and he was nice enough to invite me over this weekend. One question he asked me on the phone was "Do you listen loud?" I have never heard the Sound Labs but have always heard nice things about them. It'll be an interesting comparison.

Hi Kevin,
Sorry, I thought you were an engineer friend that owned the speakers in CA. Many thanks for your kind thoughts and feel free to contact me at any time if there is something that I can do for you. We would be pleased to have you in our Merlin family.
Regards,
Bobby
Hey guys, was just reading 6moons.com CES show report and from what I read in thier comments about the Merlin/CAT suite, apparently Merlin has any macro dynamic issues licked! :-) No complaints about dynamic compression or the ability to not play loudly... apparently it was a wee bit too loud when 6moons staff members visited! D'oh! :-0 Of course it doesn't hurt when you got 400lbs of 150W CAT JL3 triode monoblocks muscle to help deliver those clean, clear, and robust SPLs. :-) ;-)

You can see what they have to say at this link:

On a more serious note, I'm sorry if we made things difficult for any neighbors (there were no complaints though from them during the show).... at one point during the show, I recall Bobby playing the Tony Degradi Trio CD (which has some amazing dynamics) at some rather "robust" SPLs and I was getting ragged on by Bobby, Kenny, and Lee becuase I was snoozing in the nice big comfy chair in one corner of the room while this was going on. Thing is, if the sound in the room was not as clean, clear, natural, and uncompressed as it was, I would have not been 'power napping' in the corner chair, but would have been heading over to the preamp to turn it down or walking out of the room.

I wish I had a picture of you while you were sleeping. Shoes off, totally exhausted from four days of music and banter. Thanks for your help and company.

Just tell those guys you are trying to get your Zen on. They'll understand...
