I could not get rid of my 5998s fast enough. They were nos, but I could not turn my Elise past 1 o'clock without getting distortion.
Glad they are gone.

Well I've never found the DT 1990 wanting in any area, I would not call it my end game but I'm very happy with them, as to whether they are better than the T1, like you say, it's far too subjective, but I do know they pair very well with both Elise and Euforia .Regarding your own pair of T1, I read a lot about DT 1990 Pro lately and many claim it is better in some areas than T1. So I have no idea if these T1 are so good or I am just a fan of them because I found something particular for me in them. After all this hobby is somehow subjective and sometimes it is hard to advise or describe what for you sounds best.
Good luck burning in those hp's/cables, I always enjoy the process of burning in new gear, very much a journey of discovery, oh and as for Black Sabbath being "the best band in the world" I won't disagree! .
We have Black Sabbath fans here do we? Me too !
But I'll play you Temple of the King.
That's a clever Idea!It seems I've destroyed the "minimal" design of F.A, and oh boy how long I've waited for this.
With this occasion I realized I listen mosty around 20-25% of the volume with Qutest Output Level set to 3V. There are 21 markings, so 20 intervals which means 1 interval = 5%. Long live the White Permanent Marker!
I'm reviewing this thread in anticipation of my Elise being delivered next week. Quick question about the combo you reference above which is is its heat generation about the same as the stock tubes or different? I've read some info that suggests tube rolling can make a big difference in heat as well as sound sig..I was right when claiming that I'll remain a good amount of time on 7236/CV181. This combo is really very good for me and I have a that feeling of a "clinical precision". Fast, detailed, precise. Like a surgeon. LOL. Now listening to the latest Antimatter album called Black Market Enlightenment which is a delight. The percussion area is blessed with these 7236 which are really slamming.

We often have little grandchildren at the house I'm wondering if great sound and perhaps less than 300゚ C is a holy grail we can actually achieve. Also thinking of getting some type of square metal mesh to set around the the 4 tubes that won't obstruct heat dissipation but protect little fingers. Does anyone have experience trying that or similar approach?
Thanks
Thank you OctavianH for a clear and very helpful reply! Is it fair to say that none of the above variations in tube choice have a great impact on heat generation?. Also, if I were to roll just driver or power I've been told the driver is more impactful on sound signature but would appreciate your thoughts on this as well..Hi,
First of all welcome, I am glad that the Elise community is increasing. I will try to answer to your questions even if I am a newbie here compared to others. I use Elise since February 2018 and I have the MK2 model no. 145.
The heat generation is based on tube parameters and the amount of current the amp is capable to use. As far as I know the rule is that Elise can be used with tubes which not exceed 6.5A in total (all 4 tubes).
The stock tubes are 2x6SN7 as drivers (the ones in front) and 2x6AS7 as powers (or output tubes, the ones near the power transformer). The 6SN7 type are rated at 0.6A and the 6AS7 types at 2.5A which leads us to a 2x0.6+2x2.5=6.2A.
Now regarding the temperature of the tube when the amp is in usage, I guess a tube reaches somewhere at 150C but definitely you should be careful with children or pets if you plan to let them in the vicinity of the amp.
Since I do not have these problems in my house I never tried to add any protection.
When I was tube rolling, because lately I stick to the same tube combo for almost 1 year, I made a small chart which might help you:
Be aware that for some tube types you need adapters in order to be able to use them in Elise and some of the types can be plugged directly.
For example, from what I used:
1) drivers which work directly plugged: 6SN7, 6H8C
2) powers which work directly plugged: 6AS7, 6H13C, 6080, 5998, 7236
For the rest of them you will need to buy adapters from Ebay, where you can find a manufacturer which sells them at a decent price.
The name of the seller is xulingmrs and an example of such an adapter is:
https://www.ebay.co.uk/itm/1pc-Gold...463405?hash=item2ee98771ad:g:7PgAAOSw3KFWcjQm
Of course, you will need pairs of adapters.
Beside the tube types from my chart, the community is using also EL38, EL39 and EL11 (which work with the same adapter as EL12N), EL12 or EL12Spez. But here I'll let others provide more details since I do not quite use these EL tubes because all are too "sweet" for me. All of these require adapter.
EL tubes can be used in both "driver" and "power" position and many use EL11 as drivers and EL38 or EL39 as powers or you can also try EL3N / EL32 combinations. Some of us used double adapters and had 6 tubes in the same time, as long as the max current was not exceeded. An example is the 6xEL3N combo here on my amp:
And of course, if you want to go further, but I would advise to do this only after you get some experience, you can use more powerful tubes than these ones already presented with external heating and power supply. But please do not do this unless you are sure about what you are doing because it might damage the amp.
Elise is a very scalable amp and it reaches a very good performance when the rest of the line is on par. I have improved its performance a lot with upgraded cables, DAC, power filtering and so on.
I hope I have provided you correct and good information as an introduction to the amp. Feel free to ask more and I am sure that I or someone else will provide you the answer.
