SET amp comparable to First Watt SIT 1?


I’m currently planning to change my speakers to high efficiency horn from modern high end speakers (B&W). The speakers would be Volti horn speakers.

For amp, A friend of mine has First Watt SIT-1, which sounds great to my ears, but I have always been interested in tube SET, especially 300B. The problem is there are too many choices around, and I have read several online reviewers stated that 300B amps don’t sound as good as First Watt SIT 1, except extremely expensive ones with NOS WE300B.

Any suggestions?

My budget is around 7-15K. I don’t mind second hand ones, but I wish I could compare it with my friend’s SIT 1 before I decide to take it or not, so second hand unit is probably not an option.

Hello Phil,
I'm inclined to believe my EMLs were from a better batch than yours based on your comments.  I've alternated between my Takatsuki and EML XLS the past few years.  In my amplifier the EML have been simply stellar,  workhorse reliable and as quiet as any 300b I've used. There were subtle distinctions between the the KR and EML with the latter a bit more vibrant, open, alive and engaging. I certainly trust your judgement and listening impressions,  but again different set of ears,amplifier, system and room environment. IMO both are top tier choices. 

Tmare, 
I was actually suggesting you talk with the builder of  the  Volti and see what he may suggest in terms of Your room and musical tastes. I'm sure that he would provide worthwhile insight regarding his two speakers and your objectives.

You may have already considered a Line Magnetic  product, if not here is a couple for your consideration.
There are many reviews on line, that you should be able to get an idea of the characteristics of each amp.

Phil, Charles, et al.

I am a fan of the Takatsukis, but have not heard the Balloon KR 300b. That said, I can attest to the longevity of the Takatsukis. I have been using the same pair for about 5 years without any issues. I was fortunate to source a couple of pairs from Japan at a reasonable cost when they were first released. I have also found the dealers in Japan to be very accommodating - but the current price is steep and not negotiable.

While we tend to talk about output tubes and their variations, recently I have been trying different 6922/7308/etc. driver tubes and have been impressed by the impact - at least in my amplifier (custom made Ancient Audio 300b SET). I am currently using a carefully matched pair of Amperex white label, PQ shield 6922s. The difference is not subtle.

Gary,
You and I go back quite far with our mutual admiration of the superb Takatsuki. I have come to suspect my amplifier may be a little tough on some 300b tubes. In the past 4 1/2 years I had to replaced 2 individual Takasuki tubes (done without any hassle per my Japanese source AMS Tram). The EML XLS is a heavy duty constructed 300b and seems very well suited in my amplifier. Reports say this durable 300b has a life span capacity of 40,000 hours ( similar to the discontinued AVVT SL 32).

A friend of mine has a very upscale and accurate tube tester. He tested my EMLs when they were brand new 3 1/2 years ago. He recently tested them and they measure "exactly" the same and they are used frequently in my system. This is a very rugged tube that also sounds superb in my amplifier. The Elrog 300b is sublime in sound quality but too fragile for my particular amplifier.

I don’t want to bother those people with my ignorant questions,
@tmare, ignorant questions are the best ones! Never, ever worry if you are bothering the manufacturer by asking them; that should be part of why they are there!! Otherwise you might want to rethink how much support you're going to get.

I have owned OTL amps and like many of their characteristics, but I've never heard one, especially using massed output tubes, that has the sheer transparency, speed, holistic tone and spatial precision of Audion SET overall, and especially the Golden Dream monoblocks
Funny- my experience has been the opposite. Our amps have a risetime in the output section of 600V/mS, where the typical SET might be about 10V/mS. So its not only audible but measurable. Usually that's a pretty good indication that its actually real. In addition to the speed, our amps have more bandwidth as well.

Now what is going on with a specific amp on a specific speaker might really affect the outcome of your perceptions (for example a low impedance at high frequencies that one amp can drive while the other can't might make that latter seem slower even though its not). So its a good idea when doing comparisons to make sure that both amps, whatever they are, are in proper operating condition and are also a reasonable match for the speaker being used (that is, if you really want to find out what the differences are between the amps being compared).
