I am also very curious about what we can expect in terms of bass response vs the SR1-A and CA-1A in these new headphones.

Just need to shout out Danny (@SageM) for the excellent customer service and warranty coverage RAAL Requisite provides. I recently had an issue with my VM-1a. One of the power tube sockets started red plating all the time, swapping or replacing tubes didn't make the issue move but rather it...

So I know everyone has moved on to TI-1a excitement, but I want to come back tot he VM-1a and 6SL7 vs 6SN7. I did find some time today to swap in a spare Tung-Sol 6SL7 I had on hand. The increase in gain is immediately noticeable of course, and it did feel like there is some small benefit in...

Very interesting and good to know both are safe and suitable to use. I am definitely going to have to try a 6SL7 now myself. I hadn't even noticed that the labeling on the amp didn't match the pdf spec/manual and actual tube so thanks @FLTWS for spotting that! I don't think I need any...

Good to hear you are still enjoying! I am really continuing to love mine as well. Granted I was coming from a Jotunheim R as my main listening amp rather than a HSA-1B but the difference is so big and the VM-1a really lets the SR-1a reach their full potential in my opinion. Everything is warm...

I didn't have a kill-a-watt on hand to measure power usage, but have now borrowed one. In Triode mode once warmed up I get readings around 160-200 watts. In Ultralinear 160-200ish as well. I saw some short spikes up to around 220-240 in the first few minutes or so after turning on. Seems...

It shows! The headroom on the VM-1a vs the Jotunheim R is a big improvement for sure. I've been listening mostly in triode the rest of today on non-classical music with a higher average volume level and it's clear that the VM-1a really makes the SR1a shine in a way that the Jotunheim R while...

Hi new forum member here, but long time occasional lurker. I just recently bought the SR1a and a Jotunheim R a few weeks back, and now have also received a VM-1a just today. I wanted to report that I also got the Mullard tubes with mine. I'm just beginning to listen and burn in the VM-1a but...

Thanks for the advice, I am more than confident Raal will offer me great support, but I have wanted to make sure I'm having a real issue with the Jotunheim R before bugging them. In a classic audiophile move I decided I was excited enough about the SR1a so far that I should just buy a second...

New poster but long time occasional lurker here. I just got my SR1A and Jotunheim R this week and was having some clipping/distortion issues myself which seemed to be the Jotunheim. I discovered your thread and it's been very helpful. I tested the same Eroica track and immediately heard the...
